Overclocking the nvidia gtx 750 card. Maxwell in afterburner: review of the Gigabyte GeForce GTX750 Ti video card. ⇡ Cooling system - efficiency and noise level

The overclocking potential of the GM107 GPU on the new Maxwell architecture turned out to be so impressive that the vast majority of manufacturers did not fail to release overclocked versions of video cards. One of the fastest such models was in our test laboratory.

Characteristics. Equipment. Appearance

On February 18, NVIDIA introduced the new energy-efficient Maxwell architecture, the GM107 graphics processor and the first video cards based on it - and the GTX 750. Reviewers were most impressed not so much low power consumption new video card (only 60 watts) or its performance per watt, how much is the excellent overclocking potential of the core. It is not surprising that simultaneously with the announcement of the GTX 750 Ti, all famous video card manufacturers presented original models with increased frequencies (at the time of the release of the new product, eight of them were announced at once).

Moreover, if, for example, in the case of the Radeon R9 290(X) we can only talk about a formal increase in frequency by 30, 50 or 80 MHz at best, then the company was clearly not modest with overclocking. Thus, from nominal frequencies of 1020-1085/5400 MHz, EVGA overclocked its FTW version to 1189-1268/5400 MHz, Palit released StormX Dual with frequencies of 1202-1281/6008 MHz, ASUS set frequencies to 1072-1150/5400 MHz, MSI - 1085-1163/5400 MHz, Gainward - 1202-1281/6008 MHz and so on. However, the highest factory overclocking of the GPU was found in GTX video cards 750 Ti 2 GB (GV-N75TWF2OC-2GI), which we will study and test today.

Packaging and accessories

The front side of the compact box, made of thick cardboard, depicts the head of an owl with a very menacing look, as if emphasizing the most serious intentions of the product. Next to it, in addition to the video card model, there is information about overclocking its core and support for Ultra HD resolutions (4096 × 2160 at 60 Hz).

Traditionally, the more informative reverse side is reserved for a description of the features of the cooling system, printed circuit board elements and system requirements.

The video card package is minimalistic: an adapter cable for additional power, a CD with drivers and an overclocking utility, brief instructions on installation. All.

The video card is manufactured in China and should come with a three-year warranty. The recommended price is 169 US dollars, the actual retail price at the time of writing this article is from 5,600 rubles.

PCB design and features

Cooling system - efficiency and noise level

The video card itself matches its cooling system. Simple, compact and effective WindForce 2X.

The aluminum radiator is pierced three times with an eight-millimeter heat pipe, which is pressed into its center, at the same time acting as a base and in direct contact with the GPU crystal.

However, judging by the imprint of the GPU crystal on the base, the tube does not cover its entire area. It would probably be more correct to use two six-millimeter tubes, soldered to each other at the base and extending in different directions. But as it's done, it's done. Let's hope this is enough.

The entire structure is cooled by two Power Logic fans (model PLD08010S12H) with eleven translucent blades.

The actual size of the impeller is 74 mm. The fan speed is automatically adjusted in the range from 1500 to 3650 rpm by changing the voltage.

To check the temperature conditions of the video card as a load, we used five test cycles of the very resource-intensive game Aliens vs. Predator (2010) with maximum graphics quality in a resolution of 2560x1440 pixels with anisotropic filtering at 16x level, but without activating MSAA anti-aliasing:

To monitor temperatures and all other parameters, MSI Afterburner version 3.0.0 beta 19 and GPU-Z utility version 0.7.7 were used. All tests were carried out at an average room temperature of about 25 degrees Celsius in a closed housing system unit, the configuration of which you can see in the next section of the article.

Considering the extremely low heat dissipation of the new GM107, we had no doubt that WindForce 2X would cope with cooling this video card at any frequency. And so it happened.

Auto mode

Only 54 degrees on the GPU at peak load at 1346 MHz and maximum speed fans 1915 rpm. By increasing the speed to a maximum of 3650 rpm, the temperature can be reduced by another 6 degrees Celsius.

Maximum speed

But is it necessary? After all, at maximum speed the cooler begins to make noise, and at automatic mode its adjustment is simply not audible even against the background of a very quiet system unit. So for the noise level we give WindForce 2X an excellent rating.

Overclocking potential

To reduce the dependence of video card performance on the speed of the 32-nm platform six core processor with a multiplier of 48, a reference frequency of 100 MHz and the Load-Line Calibration function activated, it was overclocked to 4.8 GHz by increasing the voltage in the BIOS motherboard up to 1.38 V:

Hyper-Threading technology is activated. Moreover, 32 GB random access memory operated at a frequency of 2.133 GHz with timings 9-11-11-20_CR1 at a voltage of 1.6125 V.

Testing, which began on April 4, 2014, was carried out under the operating system Microsoft Windows 7 Ultimate x64 SP1 with all critical updates as of the specified date and installation of the following drivers:

• Motherboard chipset Intel Chipset Drivers - 9.4.4.1006 WHQL from 09/21/2013;
• DirectX End-User Runtimes libraries, release date: November 30, 2010;
• Video card drivers for AMD GPUs - AMD Catalyst 14.3 Beta v1.0 from 03/17/2014;
• Video card drivers for NVIDIA GPUs - 335.23 WHQL from 03/10/2014.

Taking into account the relatively low performance of video cards tested today, they were tested only at a resolution of 1920x1080 pixels. For the tests, two graphics quality modes were used: “Quality + AF16x” - the default texture quality in the drivers with 16x level anisotropic filtering enabled, and “Quality + AF16x + MSAA 4x” with 16x level anisotropic filtering enabled and 4x level full-screen anti-aliasing. IN individual games, due to the specifics of their game engines, other anti-aliasing algorithms were used, which will be indicated further in the methodology and in the diagrams. Anisotropic filtering and full-screen anti-aliasing were enabled directly in the game settings. If these settings were not available in games, then the parameters were changed in the control panel Catalyst drivers or . There it was forcibly disabled vertical sync. Apart from the above, no additional changes were made to the driver settings.

The video cards were tested in two graphics tests and thirteen games, updated to latest versions as of the start date of material preparation:

• 3DMark (2013)(DirectX 9/11) - version 1.2.250.0, tested in the Cloud Gate, Fire Strike and Fire Strike Extreme scenes;
• Unigine Valley Bench(DirectX 11) - version 1.0, maximum quality settings, AF16x and (or) MSAA 4x, resolution 1920x1080;
• (DirectX 11) - version 1.1.0, built-in test (Battle of Sekigahara) on maximum settings graphics quality and when used in one of the MSAA 8x modes;
• Sniper Elite V2 Benchmark(DirectX 11) - version 1.05, used Adrenaline Sniper Elite V2 Benchmark Tool v1.0.0.2 BETA maximum graphics quality settings (Ultra), Advanced Shadows: HIGH, Ambient Occlusion: ON, Stereo 3D: OFF, Supersampling: OFF, double sequential test run;
• Sleeping Dogs(DirectX 11) - version 1.5, used Adrenaline Action Benchmark Tool v1.0.2.1, maximum graphics quality settings for all points, Hi-Res Textures pack installed, FPS Limiter and V-Sync disabled, double sequential test run with total anti-aliasing at Normal level and High level;
• Hitman: Absolution(DirectX 11) - version 1.0.447.0, built-in test with graphics quality settings at Ultra, tessellation, FXAA and global illumination enabled.
• Crysis 3(DirectX 11) - version 1.2.0.1000, all graphics quality settings to maximum, blur degree - medium, glare on, modes with FXAA and MSAA4x anti-aliasing, double sequential pass of a scripted scene from the beginning of the Swamp mission lasting 110 seconds;
• Tomb Raider (2013) (DirectX 11) - version 1.1.748.0, used Adrenaline Action Benchmark Tool, quality settings at Ultra level, V-Sync disabled, modes with FXAA and 2xSSAA anti-aliasing, TressFX technology activated, double sequential pass of the test built into the game;
• BioShock Infinite(DirectX 11) - version 1.1.25.5165, used Adrenaline Action Benchmark Tool with High and Ultra quality settings, double run of the test built into the game;
• Metro: Last Light(DirectX 11) - version 1.0.0.15, the test built into the game was used, graphics quality and tessellation settings were set to High, Advanced PhysX technology was turned off, tests with and without SSAA anti-aliasing, double sequential pass of the D6 scene.
• GRID 2(DirectX 11) - version 1.0.85.8679, the test built into the game was used, graphics quality settings were set to the maximum level for all positions, tests with MSAA4x anti-aliasing and without him, eight cars on the Chicago track;
• Company of Heroes 2(DirectX 11) - version 3.0.0.13106, double sequential run of the test built into the game with maximum graphics quality and physical effects settings;
• Batman: Arkham Origins(DirectX 11) - version 1.0 (update 8), quality settings at Ultra level, V-Sync disabled, all effects activated, all DX11 Enhanced functions enabled, Hardware Accelerated PhysX = Normal, double sequential pass of the test built into the game;
• Battlefield 4(DirectX 11) - version 111433, all graphics quality settings are on Ultra, double sequential playthrough of a scripted scene from the beginning of the TASHGAR mission lasting 110 seconds;
• Thief(DirectX 11) - version 1.4 build 4133.3, graphics quality settings to the maximum level, Paralax Occlusion Mapping and Tessellation technologies activated, double sequential pass of the benchmark built into the game.

As you can see, in some games the maximum graphics quality settings were not used in order to maintain FPS at at least the minimum level acceptable for the game.

If games implemented the ability to record a minimum number of frames per second, then this was also reflected in the diagrams. Each test was carried out twice; the best of the two values ​​obtained was taken as the final result, but only if the difference between them did not exceed 1%. If the deviations exceeded 1%, then testing was repeated at least once more to obtain a reliable result.

Performance test results and analysis

• 3DMark (2013)

At nominal frequencies, the original one in 3DMark (2013) is 6-12.7% faster than the reference version of the same video card model and slightly faster than the MSI GTX 650 Ti BOOST. The AMD Radeon R7 260X is not its competitor here at all, however, no one expected this. When overclocked, the new product seriously increases its performance, but it reaches the level of the HIS Radeon R9 270 iPower IceQ X 2 Boost Clock only in the least resource-intensive testing mode.

• Unigine Valley Bench

In the Unigine Valley test the situation is different.

Thanks to the seriously increased GPU frequency, it is 12.3% faster than the regular GTX 750 Ti, but at the same time does not exceed the MSI GTX 650 Ti BOOST. Only additional overclocking of the core and memory of the video card brings it to first place, albeit with a very slight lead over the original HIS and MSI video cards.

• Total War: SHOGUN 2 - Fall of the Samurai

Total War: SHOGUN 2 - Fall of the Samurai runs faster on video cards with graphics AMD processors, so even the cheapest video card in today’s testing does not look like a “whipping boy” in this game.

At the same time, the performance level of HIS Radeon R9 270 iPower IceQ X 2 Boost Clock was not achieved by the video card even at frequencies of 1275-1354/6560 MHz.

• Hitman: Absolution

The situation is similar in the game Hitman: Absolution.

• Crysis 3

A special feature of the Crysis 3 test is the confident performance of the MSI GTX 650 Ti BOOST, which outperformed the overclocked GTX 750 Ti.

The culprit of today's “triumph” is 1-2 FPS faster than the reference version of the same video card model and even the same amount faster than the AMD Radeon R7 260X. Note that for Crysis 3 at maximum quality settings, all today's video cards are depressingly weak.

• Tomb Raider (2013)

The situation is slightly better in the game Tomb Raider (2013).

The balance of power between video cards does not change.

• BioShock Infinite

In this game, in terms of average frames per second, the GTX 750 Ti at factory frequencies is 9-11% ahead of NVIDIA and slightly faster than the MSI GTX 650 Ti BOOST. Moreover, the overclocked version is quite a bit inferior to the HIS Radeon R9 270 iPower IceQ X 2 Boost Clock.

• Metro: Last Light

As in Crysis 3 or Tomb Raider, in Metro: Last Light, even without activating Advanced PhysX technology and with simplified graphics quality settings, the performance of the video cards tested today leaves much to be desired.

• GRID 2

It’s also fast in the GRID 2 game, but it’s still far from the performance of the HIS Radeon R9 270 iPower IceQ X 2 Boost Clock even when overclocked. In general, the balance of power has not changed.

• Company of Heroes 2

In Company of Heroes 2, video cards based on AMD GPUs are in the lead.

While the first (and at that time senior) accelerator of the NVIDIA GeForce GTX 700 series was released in the spring of last year, the younger video cards, GTX 750/750 Ti, appeared only in the spring of this year. Nevertheless, these solutions became the first NVIDIA accelerators based on GPUs with the new Maxwell architecture, which aroused quite a lot of interest. We have already met the faster of these cards, the Palit GeForce GTX 750 Ti StormX Dual accelerator. The solution turned out to be quite interesting, with an original design, a good level of factory overclocking and an enhanced cooling system. Today it’s the turn of the younger representative of the pair that discovered the Maxwell architecture – the Palit GeForce GTX 750 video card.

Palit GeForce GTX 750 StormX (2042 MB GDDR5) – characteristics
For obvious reasons, NVIDIA video cards GeForce GTX 750/750 Ti look like twin brothers. They are based on the same 28nm GPU GM107 with Maxwell architecture. The nominal GPU frequency is 1020 MHz, the frequency in Boost Clock mode is 1085 MHz.

The differences here lie in the number of active computing units: the GTX 750 disables one of the five multiprocessors included in the GM107. As a result, the GTX 750 has 512 universal shader processors, 32 texture units and 16 raster operation units, while the GTX 750 Ti has 640, 40 and 16 units, respectively.

Both accelerators work with GDDR5 video memory, but for the GTX 750 Ti its clocking is 5400 MHz, and for the GTX 750 – 5000 MHz. At the same time, in the reference versions of cards for the GTX 750, a capacity of only 1024 MB is available, while for modifications with the Ti suffix - both 1024 and 2048 M. However, third-party manufacturers, of course, can operate with this parameter at their discretion , which we see in the example of the Palit GeForce GTX 750 StormX (2042 MB GDDR5) under consideration. The bus width in both cases is 128 bit, provided by two 64-bit memory controller units. At the same time, the recommended price of the GeForce GTX 750 is approximately 20% lower than that of the GTX 750 Ti, which, looking ahead, approximately corresponds to the differences in their performance levels.

The first and, in fact, the only difference between the characteristics of the Palit GeForce GTX 750 StormX (2042 MB GDDR5) video card in question and the NVIDIA reference version, as mentioned above, is the amount of video memory equal to 2048 MB instead of 1024. Theoretically, when used high resolutions coupled with “heavy” graphics settings, this feature can bring some performance gains. In addition, the memory operating frequency was increased quite slightly - from 5000 to 5010 MHz, although this is hardly worth taking into account.

It is quite natural that Palit GeForce GTX 750 StormX (2042 MB GDDR5) is not the only representative of the corresponding Palit line. The company also has a version of the GeForce GTX 750 KalmX (2048MB GDDR5), equipped with a passive and therefore absolutely silent cooling system, and the GeForce GTX 750 StormX OC (1024MB GDDR5), equipped like the reference 1024 MB GDDR5, but with significantly overclocked GPU and video memory.
Palit GeForce GTX 750 StormX (2042 MB GDDR5) – design and device
Palit GeForce GTX 750 StormX (2042 MB GDDR5) received quite simple system cooling.

It consists of a small aluminum heatsink mounted on the GPU and an 80mm fan with a shroud that covers the entire surface of the printed circuit board.

Thanks to this design, the fan simultaneously blows on the radiator, memory chips and power elements of the power converter.
The design of the Palit GeForce GTX 750 StormX (2042 MB GDDR5) PCB is completely identical to what we saw in the Palit GeForce GTX 750 Ti StormX Dual, but differs from the NVIDIA reference design.

The fundamental difference is that for some reason Palit decided not to install, as in the standard, two DVI video outputs, implementing only one - fully digital DVI-D, and instead of digital-to-analog DVI-I they installed D-Sub (VGA) , thus realizing only the analogue component of the output.

Another, albeit completely unprincipled, difference: in the NVIDIA reference design, the card has contact pads on the reverse side for four more memory chips, inherited from the older GTX 750 Ti, originally implemented, apparently, so that low-capacity chips could be used.


One way or another, 2 GB of memory of the Palit GeForce GTX 750 StormX (2042 MB GDDR5) is accumulated using four GDDR5 Samsung K4G41325FC-HC04 chips, each with a capacity of 4 GB.
Otherwise, there is only a barely noticeable rearrangement of elements, although in fact printed circuit board the card still has its own – original.
The component power converter is built according to a three-phase circuit.

Two directly power the GPU computing units, one generates voltage for video memory. Considering the power consumption of the card, it does not require additional power; all needs are covered by the slot PCI Express, therefore there is no corresponding connector on the PCB, although there are still contact pads for it.
Packaging and accessories
The Palit GeForce GTX 750 StormX (2042 MB GDDR5) is packaged in a fairly large (considering the size of the video card) box, enclosed in a dust jacket with a pleasant color design.

The delivery package is as simple as possible and consists of a user manual and a disk with drivers and software.
Since the board does not require additional power, and one of the card's video outputs is a D-Sub connector, neither power adapters nor DVI-I to D-Sub adapters were required.
Operation, temperature conditions and overclocking
At low loads, the cooling system of the Palit GeForce GTX 750 StormX (2042 MB GDDR5) video card operates quietly enough to go unnoticed against the background of a running computer. While maintaining the GPU temperature at 30˚C, the fan rotates at 30% of the maximum speed. The noise level is only slightly above the hearing threshold of 20 dBA.
When reaching the maximum possible load level, achieved using the Furmark utility, the GPU temperature eventually increases to 57°C. To maintain it, the fan had to accelerate to a speed of about 38% of the maximum.

However, this had a rather insignificant effect on the noise level emitted by the card - its value reached 26 dBA. This is a quite comfortable level for long-term gaming, so there are no complaints about the product in this regard.
In terms of overclocking capabilities, the Palit GeForce GTX 750 StormX (2042 MB GDDR5) demonstrated very good results. Thus, the graphics processor was accelerated from the standard values ​​of 1020 MHz for normal mode and 1085 MHz for Boost Clock mode to 1154 and 1219 MHz, respectively. The video memory also overclocked remarkably well, managing to reach 5882 MHz compared to the standard value of 5010 MHz. Naturally, all this while maintaining complete stability.

In real games, the GPU temperature did not exceed 50 °C and the video card still behaved quite quietly. In general, in the same real games, such overclocking allowed us to achieve a performance increase of about 12%. The result is quite pleasant, considering that to achieve it it was not necessary to increase the supply voltage of the components or put up with the deterioration temperature conditions, increased noise levels and other difficulties.
It’s great that the video card comes with a proprietary Thunder Master program, with which you can do overclocking yourself, without resorting to the help of any third-party utilities.

It is important that the software allows you to save up to five settings profiles, perform comprehensive monitoring of component operating modes, and also update the BIOS.

It is also possible to flexibly configure the algorithm for adjusting fan speeds depending on the temperature of the GPU.

Test bench and application configuration
The video card performance was tested with the following set of equipment:

• CPU: Intel Core i7-4770K ([email protected] GHz, 4 cores (8 threads), 8 Mb L3), LGA 1150;
• motherboard: MSI Z87-G45 Gaming, Intel Z87 Express;
• RAM: 2x8 GB, Transcend TX2400KLN-8GK, 2400 MHz, 11-13-11-29;
• cooler: Corsair H60 cooling system;
• power supply: Aerocool Templarius Imperator 1150W;
• Chassis: Cooler Master LAB.

The other day the GeForce GTX 750 Ti video adapter based on the new Maxwell architecture was officially presented. The newcomer aroused great interest, demonstrating good performance for his price category performance with very low power consumption. When overclocked, this video accelerator successfully competes with lower-end 256-bit graphics solutions, heats up slightly and does not require an additional power connector at all. However, the latter was still implemented in some models. Among such unique ones with additional power supply was ASUS GTX750TI-OC-2GD5. Will this help raise the overclocking bar? Let's find out now.

Following tradition, we start by inspecting the packaging. This is a small box with a standard ASUS design.

There are no additional accessories. Inside, besides the video card itself, there is only a disk with software and brief instructions.

Externally, the new model is no different from a typical representative of the budget segment with two fans made by ASUS. There are no visual differences from the R7260-1GD5 or GTX650TI-1GD5.

In this testing, we could not ignore the recently reviewed MSI N750Ti TF 2GD5/OC video adapter. Comparing its results with ASUS will help determine the importance of memory frequency during identical GPU overclocking. MSI will also act as a reference representative with Boost at 1150 MHz. All other participants are also borrowed from the previous review. The honor of the Radeon R7 260X series will be defended by two recent heroes of our review section - Gigabyte GV-R726XOC-1GD and MSI R7 260X 2GD5 OC. The GeForce GTX 650 Ti Boost will be performed by Inno3D iChill HerculeZ 2000 at specially adjusted frequencies, so that the final Boost indicators are close to the frequencies of the standard version. Similarly, the standard version of the GeForce GTX 660 was obtained from the MSI N660 TF 2GD5/OC. The most powerful participant is the Radeon R9 270 (ASUS R9270-DC2OC-2GD5).

Below are the official frequency data. The graphs show the full range of NVIDIA core operating frequencies, including peak Boost values.

Test results

Energy consumption

conclusions

The reviewed ASUS GTX750TI-OC-2GD5 video card demonstrated good temperature and noise characteristics at nominal values, but not as outstanding as those of the MSI N750Ti TF 2GD5/OC. The performance of both of these cards at factory frequencies is as close as possible. There is a trend where ASUS is a little weaker. But this difference is so tiny that it does not play any practical role. GPU overclocking is standard. It only confirms our assumption that all variations of the GeForce GTX 750 Ti that will be released have the same potential. So the performance gain will largely depend on the memory potential. And here ASUS loses to its rival. The GTX750TI-OC-2GD5 is approximately 10% inferior to the mentioned MSI N750Ti TF 2GD5/OC video adapter in terms of maximum frequency memory, which results in a performance lag of 3-7%. Still, ASUS holds its own against the Radeon HD 7850. And the power consumption figures are even better than those of MSI. So the ASUS GTX750TI-OC-2GD5, although it does not reach the level of the best representatives of the GTX 750 Ti series, is still a worthy candidate for purchase.

This video card is the first to be assembled on the Maxwell architecture. It consumes much less energy than all previous models and is highly efficient. It has also attracted fans of overclocking video cards, as it has good capabilities for this. Many manufacturers took advantage of this and released several versions of it at once.

For example, we can highlight EVGA - they released 4 models at once, and ASUS - 3. And of course, Gigabyte, MSI and Palit did their best, we will discuss them a little later.

Specifications

additional characteristics

Manufacturers

Gigabyte GeForce GTX 750 Ti OC 2 GB (GV-N75TWF2OC-2GI)

Gigabyte released three versions of the card, but this one is the best, and has the fastest core frequency.

It is made in China and comes with a 3-year warranty. The retail price started at 5,600 rubles.

The model is compact and at the same time attractive. The fan has translucent blades, which is pleasing to the eye.

The design is slightly spoiled by the heat pipe that goes up, but that's okay, because you can ignore it.

The Nvidia version has three outputs: DVI-I, DVI-D and one mini HDMI, while Gigabyte has DVI-I and DVI-D (both Dual-Link), as well as two full HDMI connectors version 1.4a.

The last two make it possible to output images in UltraHD.

This card does not need additional power, but when compared with the reference card, Gigabyte installed a connector for additional power. This was not difficult to do, since the original printed circuit board is used, which already has contacts for it.

The power of the power supply that is required is slightly increased from 300 to 400 W.

The video card has 2 GB of GDDR5 video memory. It operates at a clock frequency of 5400 MHz.

Gigabyte GeForce GTX 750 Ti OC has a fairly simple, convenient and effective cooling system.

The maximum temperature of the GPU, which was recorded during tests, was 54 degrees, despite the fact that the fan was running at maximum speed in automatic mode.

The graphics core was decently overclocked at the factory, and there was no hope for any further overclocking, but we still managed to add 60 MHz to the graphics processor, and raise the video memory to 1160 MHz, despite the fact that the image remained at a decent level, without defects .

MSI GeForce GTX 750 Ti Gaming 2 GB (N750Ti GAMING 2GD5/OC)

MSI tried even harder and released 4 video cards at once. Each of which has a different amount of video memory and frequency.

The card manufacturer is China. It comes with a 2 year warranty. Sales in Russia started at a price of 5,400 rubles.

Any fan of MSI products will recognize the style of the card. Its entire front side is hidden under two fans.

The output panel has one DVI-D, one D-Sub and one HDMI quite old version 1.2.

You need a power supply with a power of at least 400 watts

The initial processor clock frequency is 1085 MHz. In boost mode, it is possible to increase up to 1163 MHz.

The model has 2 gigabytes of video memory. It operates at a frequency of 5400 MHz.

The video adapter has a stripped-down version of the MSI Twin Frozr IV cooling system. Its simplicity lies in the fact that instead of four heat pipes it has only two.

Graph. the processor heated up to 54 degrees, given that the cooler was operating at maximum speed.

The core can be overclocked to 185 MHz, and the video memory to 1240 MHz.

The final frequencies of the video card: 1270-1348/6640 MHz, and in boost mode we got an excellent result - 1414 MHz. Very good considering that after overclocking the temperature remained the same.

Palit GeForce GTX 750 Ti StormX Dual (NE5X75TT1341-1073F)

This company pleased us with only two video adapters. The most effective among them is StormX Dual.

It is produced, of course, in China. The retail price started at 5,200 rubles, and the warranty period is 2 years.

The design is certainly not the best, but it still looks acceptable. The entire front part is covered with plastic.

It has the following outputs: DVI, D-Sub and mini-HDMI.

The GPU operates at a frequency of 1202-1281 MHz. Video memory frequency – 6008 MHz. Volume – 2 GB.

The installed cooling system is StormX Dual.

The cooler is quite effective; the GPU temperature did not rise above 64 degrees during tests.

When overclocked, the results are slightly modest. It was possible to achieve an increase in the graphics processor by 55 MHz, and an increase in the video memory frequency by 640 MHz.

Final video card frequencies: 1257-1336/6648 MHz.

Comparison with other video cards

The table shows comparisons with such reference options as NVIDIA GeForce GTX 650 Ti BOOST, NVIDIA GeForce GTX 650 Ti and AMD Radeon R7 260X.

Overclocking

Using MSI program Afterburner you can increase the base frequency to 1155 MHz.

The video memory frequency can be overclocked to 6524 MHz. At the same time, energy consumption will also increase, so a balance is needed.

Overclocking also increased the heating of the GPU to 69 degrees.

Benchmark tests

Based on the tests carried out in 3DMark, we can say that video cards from various manufacturers don't make much difference. GeForce GTX 750 Ti is in the lead Palit GeForce GTX 750 Ti StormX Dual is in the lead.

Tests in games

Tests were carried out at maximum resolution in several popular games and the following results were obtained:

Conclusion

We can confidently say that the video card has fulfilled its task. Energy consumption was reduced by almost half and productivity was increased. Although there are power restrictions, we still managed to overclock quite well.

It is certainly not a gaming video card and is even a little expensive for its performance. If its cost was within $100, it would be much more successful.

Hello dear friends!
As a supporter of the best, I am not used to denying myself, so I assembled the computer myself and only from expensive components. True, not all hardware came out of the top category; due to a limited budget, I had to temporarily switch to AMD Athlon II X4 750K and a cheap mother from ASRock. The processor and mother were purchased on a budget budget so that they would be enough for a more expensive video card and SSD. At that time I was more interested in games, so a good video card remained a priority, as well as solid state drive. I approached the choice of a video card very sharply - below 7 thousand is not a video card. Therefore, the then-fresh GTX 560ti, with good factory overclocking and cooling, was chosen. And even now, after more than three years, I don’t understand how you can play on budget video cards. Now the computer has an R9 280X, some will call it a budget option, preferring the 780 from NVidia. But the 780 is not affordable for everyone, unlike the 280X.

In this article I want to look at a budget video accelerator from MSI - GTX 750ti TF. Actually, the review is not being done for the sake of the review, but to prove to myself and others like me that there is “life” below 7,000 rubles. It’s not for nothing that video cards are released at such a price.

Packaging and accessories

Packaging is made in standard style and color for the Gaming series of video cards. On back side The advantages of this series are briefly described.

The package contains another black box with the Gaming series logo. It contains a booklet about the Gaming product series, a software disc, a user manual and a card about the advantages of a dual BIOS video card. DVI-VGA adapters and molex--6pin are not, since they are not needed - the card has enough power supply PCI-E bus, and the monitor can be connected via VGA.

The video card itself lies securely in an antistatic bag, protected by foam rubber.

Appearance and Design
The video card is made in black colors, with a red insert along the length of the plastic casing, and the Gaming logo in the middle.

The length of the video card is only 250 mm, don’t be afraid - it will fit in almost the shortest cases.
The width of the board is 37 mm, so it can easily cover a couple of slots on the motherboard.

On the reverse side you can see a metal stiffener, designed to increase the resistance of the video card board to bending under the weight of the cooling system. It looks a little dubious, not in terms of strength, but in terms of necessity - the CO of the video card is not so heavy as to strengthen the PCB with additional metal.

To connect the monitor, a not entirely standard set is used - HDMI, DVI-D and even D-Sub, which will significantly simplify connecting the monitor; you won’t have to go to the store if you forgot the adapter.

Cooling system

The video card is equipped with an MSI Twin Frozr IV cooling system. It consists of a pair of heat pipes, with direct contact with the processor crystal.

The aluminum radiator consists of 36 plates and is pierced by a pair of copper U-shaped tubes of various thicknesses - 6 and 8 mm. MSI claims a doubled heat transfer rate due to proprietary SuperPipe heat pipes.

The radiator is cooled by a pair of Power Logic fans with a diameter of 94 mm and marked PLD10010B12HH. The fans themselves are made using Airflow Control technology - specially curved edges of the blades direct a larger volume of air directly to the heat pipes, thereby allowing heat to dissipate much faster.

The fans are connected to a 4-pin power connector.

Printed circuit board

The printed circuit board is made in black color scheme. In the middle is the NVIDIA Maxwell GM107-400-A2 graphics chip.

The video memory capacity is 2 GB. The memory itself is composed of four GDDR5 chips manufactured by SKhynix H5GC4H24MFR - 512 MB each.

The uP1608TK PWM controller from uPI Semiconductor is responsible for managing the power of the GPU.

The board for the MSI N750ti was based on some more energy-intensive card, since there is an empty slot for an additional power connector. Additional power as such is sufficient for the video card via the PCI-E line. To the left of the missing connector is the BIOS switch. The video card supports Hybrid BIOS technology, and the second position of the switch allows you to use UEFI BIOS.

The power supply system is four-phase - three phases for the graphics processor, one for the video memory and circuits.

Despite its low cost, the MSI video card is built using all proprietary technologies used in more expensive models from this company. Solid CAP capacitors with an aluminum core, ultra-low ESR resistance and a guaranteed ten-year service life are used. Economical Hi-c CAP capacitors with increased energy efficiency up to 93%, new SFC coils (Super Ferrite Choke) with a ferrite core with super conductivity, increased energy efficiency by 20% and energy capacity by 30%. In addition, they should be 35 degrees Celsius cooler during operation.

Overclocking and tests

We start by identifying the video card by the system, GPU-Z helps.

The video card was overclocked using MSI Afterburner. 1260 MHz for the graphics core and 6020 for the memory frequency turned out to be stable. All attempts to raise the memory frequency higher led to artifacts in tests at best, and system freezes at worst.

Unigine Heaven Benchmark 4.0 (DirectX 11)

The video card passed this test without any problems in normal mode and without any hiccups during overclocking.

But the video card passed this graphics test only without overclocking. When overclocking, literally after 10 seconds of the first test the video card froze.

All tests in games were carried out on high settings at a resolution of 1920x1080, the latest driver revision is 344.48.

The video card, despite its price, shows very good results. But it’s worth considering one important point - the settings in the games were not ultra. I wanted to test it on ultra to know what it was capable of, but after the first game I changed my mind about making fun of myself and the card - it was just a slide show. But even at high settings, almost any game looks great, considering its price and low requirements for the power supply.

conclusions

I have definitely proven for myself that you can play well for up to 7 thousand rubles. The question is how long will this card last? Is there any point in buying it? Exit of each new game raises the bar for requirements for video accelerators in computers. The next new and long-awaited game may present you with a choice - play at low FPS and graphics from past years, or go and fork out for a good video card. Everyone decides this for themselves.

As for the MSI GTX 750ti, this is an excellent video card for the money - it does not require a powerful power supply, is quiet and moderately productive (taking into account overclocking). And no need to think about my bias, I just really liked the video card. I happened to run various video cards from different manufacturers on my system - some don’t run at all, others make noise when heating up, and others need a powerful power supply. The only doubt that is not in favor of choosing the MSI GTX 750ti is its price. For its price and even a little cheaper, you can look at quite fast video cards that will show more playable FPS with the same settings. You don’t have to look far for examples - from the same NVidia GTX 660 and AMD R9 270. However, everyone is free to choose what they like, there is no doubt about one thing - MSI know how to make video cards and make them well.
