Overclocking nvidia geforce gtx 750 ti. Video cards. Comparison with other video cards

Nvidia is the undisputed leader in the budget video card market. Their products are replete with options available at low prices, but have not lost their relevance. One such example is the Nvidia Geforce GTX 750.

The video card is powered by a 28nm GM107 processor based on the Maxwell version architecture. The core size is 148 square millimeters. The base core frequency is 1020 MHz. The frequency in Turbo mode is 1080 MHz.

Memory capacity – 2 GB GDDR5 type. Memory bus – 128 bits. The effective memory frequency is 5400 MHz. Bandwidth – 86.4 GB/s.

Based on these characteristics of the GTX 750, we can conclude that even despite its low cost, it is an excellent option in terms of price and quality ratio. The power of the video card will be enough to run modern games and programs.

GTX 750 review

This video accelerator is the best option for building an inexpensive computer. The main thing to do when assembling a PC is to decide on the processor and power supply.

Power consumption of GTX 750 – 55 W. From this it follows that the best option would be a 300 W power supply. Even if there is powerful processor, the specified volume will be sufficient.

How to overclock an Nvidia Geforce GTX 750 video card for mining

Due to the rapid growth in popularity of cryptocurrency, people are increasingly wondering whether mining is possible on the GTX 750.

Although this model has the status of an office one, you can mine cryptocurrency on it. Overclocking will help in this matter Nvidia video cards GeForce GTX 750.

To do this, you will need three main overclocking programs:

1. MSI Afterburner.
2. GPU-Z.
3. Funmark.

The first utility is responsible for the overclocking process, the second allows you to monitor performance.

The first step is to increase the "Power Limit" settings to 110% in MSI Afterburner. Next, we increase the “Core Clock” indicator by 30-40 MHz, but no more.

Using Funmark, we check the performance of the video accelerator using a stress test. If no failures are detected, then you need to proceed to increasing the “Memory Clock” indicators to 150-170 MHz in Afterburner.

The result of increasing the characteristics will be displayed in the GPU-Z program. This overclocking will be enough for cryptocurrency mining.

Game test results

To test the GTX 750 in games, we selected the most popular and demanding options to date. These include:

• Crysis 3;
• Battlefield 1;
• Tomb Raider;
• Grand Theft Auto 5;
• The Witcher 3;
• Assassin's Creed: Origins;
• Watch Dogs 2.

At maximum settings in FullHD format, the average FPS is 14-40 frames per second. To get the optimal number of frames, you need to configure your video card Nvidia GTX 750 for games. The program can help with this GeForce Experience, which allows you to produce automatic setup for any game.

Comparison of manufacturers

To get a complete picture of a video card, you need to take a closer look at its manufacturers, their characteristics and price.

Latest drivers

To obtain maximum performance from the operation of the video card, you need to download drivers for Nvidia Geforce GTX 750 from the manufacturer’s official website. You can also do this on our website by following the link.

It is important not to forget to update the drivers for the Nvidia Geforce GTX 750 video card. New driver versions are released every 2-3 months. Each version improves performance in games, most often new ones.

GeForce GTX 750 Ti review | GPU Boost and Overclocking

Factory clocks and GPU Boost

We already know that the base clock speed of Nvidia GPUs does not provide insight into how the processor will perform under load, since GPU Boost technology is used under certain conditions.

The parameters of the base frequency and frequency in GPU Boost mode can be set by the card's partners in the firmware. Therefore, depending on the cooler and the card itself, there may be discrepancies within the Boost frequency range, even if the products have the same base clock speed. The following chart shows Gigabyte at its most modest limit. However, the card can support this frequency without fluctuation. The other three cards, which do not have auxiliary power connectors, show some changes in this indicator.

Overclocking? Yes, but minor

After extensive stability tests on partner cards, we came to the conclusion that the highest stable GPU Boost frequency is ~1.3 GHz. At this point the TDP limit introduces its limitations. Unfortunately it is set to 100%. Until Nvidia removes the barrier to setting higher power limits, you won't be able to squeeze more performance out of this graphics card (it's limited by the PCI Express limit of 75 W).

In terms of performance, the Gigabyte and MSI models turned out to be very close. The GTX 750 Ti Gaming OC was able to achieve a higher peak frequency, but the latter dropped very often due to TDP limitations. Gigabyte's solution demonstrates more balanced behavior. Additionally, the card runs at a fairly low temperature of 46°C despite overclocking.

First we'll compare the base clock settings with the observed GPU Boost clocks:

It is clear that the higher the overclocking frequencies, the more often the card lowers them. In practice, this means that you will not receive any special advantages during the game. Let's compare the increased frequencies with the normal ones in the games Metro: Last Light and Crysis 3, the indicators of which we normalized and brought to the average value.

Increasing the base frequency by about 14% (11% in GPU Boost mode) gives about a 7% increase in speed in games. At the same time, energy consumption barely fits into the power budget, and GeForce GTX 750 Ti does not exceed TDP limits. Short bursts (102%) are immediately compensated by lowering the clock frequency. But by limiting the power limit to 100%, we got a fairly modest speed boost, regardless of whether additional power was required from the auxiliary connector or not. Before overclocking further, Nvidia needs to fix the power limit in software.

GeForce GTX 750 Ti review | GPGPU: floating point speed

Single precision is good. Double precision is bad

Nvidia Kepler GPUs offer double-precision compute performance at 1/24 FP32 compute speeds. Maxwell is even worse in this regard - 1/32. Of course, this is all theory. It is better to double-check this parameter in realistic tests.

The Folding@Home benchmark is especially suitable for comparing graphics cards with OpenCL. This time we will have to do without CUDA indicators, since the Maxwell-based card was not recognized correctly. You'll have to check this setting later.

How big is the difference between single and double precision calculations? Our test results showed a ratio of 8:1 per GeForce GTX 750 Ti(Maxwell). This is noticeably lower than GeForce GTX 760(Kepler) - 4:1 in our test (Explicit Solvent).

However, GM107 is different high rate single precision calculations. The new model in this regard can compete with much stronger graphics adapters. For double precision calculations, the computational throughput is a bit lacking.

Single-Precision or SP tests

Double-Precision or DP tests

It's hard for us to make any specific conclusion regarding the capabilities of the GM107 in FP64. We can say that the speed of calculations with double precision is bad, but with single precision it is good. In any case, the artificial restrictions that block cheap desktop graphics cards from making it to workstations still irritate us.

GeForce GTX 750 Ti review | GPGPU: Bitcoin, Litecoin, LuxMark and RatGPU

The following subjects do not cover all aspects of general-purpose computing (our test suite also includes Photoshop, WinZip, and video editing tests that we were unable to complete). Still, they give a good idea of ​​Maxwell's improvements over Kepler, as well as where Nvidia stands relative to AMD now.

BTC Mining

While the company hasn't provided details on the improvements, we do know that Maxwell is much faster at hashing than Kepler, which is reflected in its win over GeForce GTX 680 And GeForce GTX 770. However, in BTC mining GeForce GTX 750 Ti loses Radeon R7 260X and some other mainstream AMD graphics accelerators.

Naturally, Bitcoin is not the only cryptocurrency that relies on hashing. For example, MaxCoin is part of the SHA3 family, and is supported in new version CudaMiner. We became curious about the position GeForce GTX 750 Ti towards GeForce GTX 650 Ti and we ran the following SHA2 test in Sandra 2014:

DirectX Compute Shader registered a significant increase, but throughput via CUDA is simply amazing. Maxwell likely improved integer processing, which was slow on Kepler. We hope Nvidia will talk more about the capabilities of the new architecture.

LTC Mining

Bitcoin mining on CPUs and GPUs is practically irrelevant today only because it is simply impossible to compete with specialized ASIC and FPGA devices. But for at least a little while longer, Litecoin remains a viable option. Using the script ( key function password-based output) in the proof-of-work algorithm instead of Bitcoin SHA-256 complicates the development of special equipment. So the GPU is still at the helm, even though, due to ongoing difficulties, investment in components often exceeds the income from currency mining.

Historically, Nvidia cards have been competitively inferior to Radeons, which is why we're seeing them sell for $700 and up. However, improvements to the Maxwell architecture allow 60-watt GeForce GTX 750 Ti overtake 140-watt GeForce GTX 660 and get closer to Radeon R7 265(150 W), which after the premiere has not yet gone on sale, but is expected to cost $150. On the performance scale (in kH/s (kH/s)) per watt, Nvidia is ahead of AMD. Today, four cards with GM107 chips in a mining system will be able to outperform, while you will spend less money on the cards themselves and on electricity bills.

LuxMark 2.0

LuxMark is another AMD stronghold, where the compute performance of its GPUs tends to be significantly higher than that of competing Nvidia solutions. In fact, Radeon cards are so far ahead of Nvidia that the latter does not even comment on these indicators, stating only that the company's gaming cards are not optimized for computing tasks.

But again, for a 60-watt card GeForce GTX 750 Ti I did an excellent job. It still lags behind Bonaire chip cards in this price segment. But compare its score (943) with the GeForce GTX 580 (893). In case you forgot, the 580 is a former flagship with a power consumption of almost 250 W!

GeForce GTX 750 Ti review | Professional Applications

AutoCAD 2013: 2D Performance DirectX (Cadalyst)

Despite the close results of all tested video cards, the model with the Maxwell chip showed a slight advantage. This test shows that 2D functions no longer access directly hardware(except for blitzing and stretching), which causes bottlenecks to arise in other platform components. However, there is enough performance for any occasion.

AutoCAD 2013: 3D Performance DirectX (Cadalyst)

U GeForce GTX 750 Ti quite an interesting position in Cadalyst 3D. Improved single-precision performance is evident. After all, DirectX uses SP primarily in its libraries, and all the vertices and their transformations are useful most often in this simple 3D presentation.

Autodesk Inventor 2013: DirectX

We again use the extreme problem with 1000 cubes. Contrary to what we saw in Cadalyst, GeForce GTX 750 Ti performed quite as expected, given the position of this card on the market.

Maya 2013: OpenGL

Finally, we have a benchmark that measures OpenGL performance. It is computationally intensive and memory dependent. The point is that theoretical performance doesn't reflect real-world behavior, and less powerful graphics cards often achieve better results, which is always interesting.

• Motherboard: Asus Maximus VII Hero (BIOS v 0904);

• Helper utilities:
• GPU-z v. 0.7.9;
• Heaven Benchmark 4.0;
• MSI Afterburner v4.0.0 Final;
• MSI Kombustor 2.5.

Testing tools and methodology

To overclock video cards, as well as monitor temperatures and fan speeds, the proprietary MSI Afterburner v4.0.0 Final utility was used.

The stability of the accelerators during overclocking was checked using the MSI Kombustor 2.5 utility (GPU Burn-in mode, 1920 x 1080). The obtained frequencies were additionally checked by runs of the Heaven Benchmark v 4.0 test with an extreme level of tessellation and graphics tests from the 3DMark 2013, 3DMark 11 and 3DMark Vantage packages.

To check the temperature conditions of video cards in conditions close to everyday conditions, Heaven BenchMark v was used. 4.0 (quality: ultra, tessellation: extreme, AA8x, 1920 x 1080).

The noise level was measured using a TM-102 digital sound level meter with a measurement error of no more than 0.5 dB. The measurements were taken from a distance of 0.5 m. The background noise level in the room was no more than 28 dB. The room temperature was 26 degrees Celsius.

Standard frequencies and overclocking

Test Inno3D GeForce GTX 750 Ti OC

This model comes with factory overclocking: base overclock to 1046 MHz core versus 1020 MHz for the reference version of the GeForce GTX 750 Ti, in Boost mode – 1111 MHz at a voltage of 1.150 V versus 1085 MHz. The memory frequency is left unchanged – 1350 MHz.

In no-load mode, frequencies dropped to 135/202 MHz, temperature GPU during such operation was 29°C, and the noise emitted by the cooling system can be called very low.

Under load, GPU Boost 2.0 technology gives the graphics card the opportunity to show its character. The graphics core frequency was 1189 MHz, and the temperature did not exceed 68°C. The installed fan coped with its task at an impeller rotation speed of 1050 rpm, and the noise emitted was minimal.

How are things going with overclocking? It was difficult to find stable frequencies of the video core and memory, but my attempts were rewarded: 1196 MHz and 1600 MHz, respectively; in gaming applications the clock frequency reached 1334 MHz. Not a bad result.

It is worth noting that, despite the possibility of increasing the voltage by 31 mV, overclocking took place at the standard value, since as the voltage increased, the power consumption of the video card increased, and it, in turn, reduced the clock frequencies.

Now we present a graph of the dependence of temperature and noise on the fan speed of the Inno3D GeForce GTX 750 Ti OC video card.

KFA2 GeForce GTX 750 Ti test

This model did without factory overclocking, its core frequency in normal mode was 1020 MHz, in Boost mode it was 1085 MHz versus 1033 MHz at a voltage of 1.131 V. The memory frequency remained the reference one - 1350 MHz.

When idle, the video card dropped frequencies to 135/202 MHz. The temperature dropped to 30°C and the noise emitted was low.

When turning on a “heavy” game, the video card came to life, and thanks to GPU Boost 2.0 technology, the core frequency increased to 1176 MHz. It is worth noting that installed system cooling did not allow the GPU to warm up above 56°C. At the same time, the noise emitted was low and was recorded only when the side wall of the case was open.

Let's move on to acceleration. And here everything is not bad: the core and video memory frequencies were 1240 MHz and 1675 MHz, respectively, and in Boost mode even 1381 MHz. An excellent result for such a baby!

At the end, it is worth giving a graph of the dependence of temperature and noise on fan speed, which will more clearly show the efficiency of the cooling system.

Test Palit GeForce GTX 750 Ti KalmX

The Palit video card is deprived of factory overclocking for the sake of the performance of the passive cooling system, so the frequency formula looks like 1020 MHz for the core and 1350 MHz for the memory.

Its idle frequencies dropped to 135/202 MHz, and the GPU temperature was fixed at 31°C. I think there is no point in writing about the noise level, it simply doesn’t exist.

Let's move on to the load. Everything is not bad here: the second version of Boost ensured that the video core operated at a frequency of 1163 MHz, the memory functioned at the required 1350 MHz.

In this state, I was unable to warm up the GPU above 57°C. The result is impressive considering the fact that KalmX's original passive cooling system operated without additional airflow in a closed case.

It should be noted that it was decided to test the acceleration without additional airflow in order to determine the efficiency of the CO. The video card achieved a core frequency of 1240 MHz (Boost 1305 MHz), the memory did not disappoint - 1700 MHz. A worthy result, considering the fact that in applications the GPU frequency was 1366 MHz.

In this case, there is no point in showing a graph of the dependence of temperature and noise on fan speed, since the Palit GeForce GTX 750 Ti KalmX worked in passive mode. One has only to say that the highest temperature value was recorded in game The Witcher 2: Assassins of Kings and was equal to 62°C at reference frequencies, in other cases its value was in the range of 55-58°C.

Zotac GeForce GTX 750 Ti OC test

In turn, the Zotac GeForce GTX 750 Ti OC model comes with factory overclocking, as indicated by the “OC” suffix. The base core frequency was increased from 1020 MHz to 1033 MHz (in Boost mode - from 1085 MHz to 1111 MHz) at a voltage of 1.137 V. At the same time, the video memory frequency remained untouched - 1350 MHz.

When idle, the accelerator dropped frequencies to 135/202 MHz, and the GPU temperature was set at 30°C. The noise level emitted by the fan can be described as low.

Under load, thanks to GPU Boost 2.0 technology, the video core frequency increased up to 1176 MHz. At the same time, the cooling system did not allow the graphics processor to warm up above 64°C, operating at 45% of its capacity. maximum power. This approach ensured fairly quiet operation of the video card.

But what testing without overclocking? After an hour and a half of all sorts of games and tests, the process stopped at 1258 MHz for the core (in Boost mode - 1336 MHz) and 1725 MHz for memory. And thanks to GPU Boost 2.0, the core frequency was several points higher and amounted to 1358-1387 MHz.

At the end, it is worth giving a graph of the dependence of temperature and noise on the speed of the cooling system fan.

GeForce GTX 750 Ti performance

Performance in gaming applications has been examined repeatedly in the laboratory. Here are just a few links:

The baby KFA2 GeForce GTX 750 Ti is not a simple video card and can give other full-size solutions a head start. Due to its small size, this model will be an excellent choice for building compact systems, and coupled with an efficient and quiet cooling system, you can forget about its existence when watching a movie on your HTPC.

Looks like an interesting character graphics accelerator Palit GeForce GTX 750 Ti KalmX with a passive cooling system, which turned out to be balanced, with a high-quality element base and silent CO. It can be recommended to users who want a productive solution in their systems that provides proper cooling and does not distract from their favorite game with noise: just put it in and forget it. And the extended three-year warranty can be considered a plus.

But the Zotac GeForce GTX 750 Ti OC model stands apart. Interesting appearance, excellent factory potential, high quality element base, a good package and, at first glance, a slightly inferior cooling system to its competitors in efficiency. But if you take a closer look, everything is in order here, because a temperature of 65°C (or even 70°C) cannot be called critical. There is no need to talk about the level of noise emitted - at low fan speeds the video card is practically silent, and it is in this state that it operates in automatic mode.

Nefedov Peter aka Go.d-bq

We express our gratitude to:

• Regard Company for providing Inno3D GeForce GTX 750 Ti OC, KFA2 GeForce GTX 750 Ti, Palit GeForce GTX 750 Ti KalmX and Zotac GeForce GTX 750 Ti OC video cards for testing.

On February 18, NVIDIA introduced the new energy-efficient Maxwell architecture, the GM107 graphics processor and the first video cards based on it - the GeForce GTX 750 Ti and GTX 750. Reviewers were most impressed not so much by the low power consumption of the new video card (only 60 watts) or its performance per watt. excellent overclocking potential of the core. It is not surprising that simultaneously with the announcement of the GeForce 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 with the overclocking of the GeForce GTX 750 Ti the companies were clearly not modest. Thus, from nominal frequencies of 1020-1085/5400 MHz, EVGA overclocked its FTW version of the GeForce GTX 750 Ti 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 overclocked GPU was found in the Gigabyte GeForce GTX 750 Ti 2 GB video card (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 (4096x2160 at 60 Hz).

Traditionally more informative back 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

The Gigabyte GeForce GTX 750 Ti turned out to be a compact, neat and at the same time quite attractive video card. Its dimensions are 190x133x38 mm. The sleek contours of the thin plastic fan frames and the fans themselves with translucent blades give the product a finished and sophisticated look.

The heat pipe extending upward somewhat spoils the overall picture, but in the end you can ignore it. The turquoise color of PCB, often used in Gigabyte products, is what I personally like most in printed circuit boards. But this is a matter of taste. All this, of course, is great, but you will rarely see the video card itself, so let’s move on to its equipment.

Unlike the reference version of the NVIDIA GeForce GTX 750 Ti, which has DVI-I, DVI-D and one mini HDMI outputs, Gigabyte has DVI-I and DVI-D (both Dual-Link), as well as two full-fledged connectors HDMI version 1.4a.

Thanks to the presence of the latter two outputs, the Gigabyte GeForce GTX 750 Ti can output images with Ultra HD resolution (4096x2160 pixels) at 60 Hz.

As noted above, the GeForce GTX 750 Ti uses 60-watt power via the PCI-Express bus, so the reference versions of this video card are not equipped with a connector for additional power. Another thing is the Gigabyte GeForce GTX 750 Ti, during the development of which the engineers did not skimp on power and installed one six-pin connector on the video card.

However, on standard printed circuit board, which is used here, has a contact pad for this connector, so the modification in this case turned out to be minimal.

The power supply system has not undergone any amplification (since the advent of the GeForce GTX 650 Ti); it uses two phases for the graphics processor and one for memory with power circuits.

The GPU crystal, measuring 12x13 mm, is placed on a substrate without a protective frame. It was not present on the reference version of the GeForce GTX 750 Ti, so it is strange that manufacturers of serial video cards did not bother to protect 1.87 billion of the most modern transistors. Our GM107 is an A2 version and was released in Taiwan in the 8th week of 2014 (mid-February).

The base GPU frequency in 3D mode has been increased by 195 MHz, or 19.1%. In boost mode, the frequency can increase to 1294 MHz, and according to monitoring data, it rose to - attention - 1346 MHz! Impressive, isn't it? To date, no commercially produced video card operates at this frequency in 3D mode. When switching to 2D mode, the frequency drops to 135 MHz. The ASIC quality of our Gigabyte GeForce GTX 750 Ti processor is rated at 70.4%.

As for video memory, everything is standard here: 2 GB, GDDR5, FCBGA packaging, SK Hynix chips (labeled H5GC4H24MFR-T2C), effective frequency - 5400 MHz, theoretical bandwidth - 86.4 GB/s.

Let us add that when the video card switches to 2D mode, the memory frequency is reduced to 810 MHz.

GPU-Z will tell us all the characteristics of the Gigabyte GeForce GTX 750 Ti.

We supplement the review of the video card with a link to its BIOS - and straight to the cooling system.

⇡ Cooling system - efficiency and noise level

The video card itself is matched by 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 fans Power company Logic (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 Gigabyte GeForce GTX 750 Ti video card, we used five test cycles of the very resource-intensive game Aliens vs. Predator (2010) at maximum quality graphics 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 fan speed of 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 in the automatic adjustment mode it is simply inaudible even against the background of a very quiet system unit. So we give the Gigabyte WindForce 2X an excellent rating for its noise level.

⇡ Overclocking potential

Understanding that the Gigabyte GeForce GTX 750 Ti was already seriously overclocked on the core at the factory, we did not hope for any further possible increase in frequencies, but we were still able to squeeze an additional 60 MHz out of the GPU. The video memory was an order of magnitude more pleasing, overclocking to 1160 MHz without loss of stability.

The final frequencies after overclocking the video card were 1275-1354/6560 MHz.

At higher frequencies under the same testing conditions, the Gigabyte GeForce GTX 750 Ti began to heat up slightly more: the GPU temperature increased by 2 degrees Celsius, and the fan speed increased by a few tens of revolutions per minute.

Note that at some points the frequency of the overclocked GPU increased to 1406 MHz. On air. Quiet air...

The compact and inexpensive board from Palit Microsystems Ltd is also equipped with an exclusive cooling system with a Palit TurboFan Blade air supercharger, the design of the blades of which was borrowed from turbojet engine fans. This design allows you to increase air flow at current speeds and thereby effectively combat overheating, demonstrating low noise levels. Among other things, the manufacturer has also improved the component base: replaced the standard capacitors with more reliable solid-state ones, used ferrite cores and modified the pulse-width modulator.

Conclusion

It cannot be said that the test results revealed something new for us. The result was predetermined by the given frequency characteristics. There was hope for possible overclocking potential, but there were no surprises here either. We have many similar video cards, with good cooling and sufficient performance for a mid-range system. Today, while developers are just looking at gaming platforms, and there are no particular reasons for increasing the load on video adapters, models based on NVIDIA Maxwell will be relevant for at least a couple of years.

However, there are significant differences between our competitors, despite having an identical platform. Enthusiasts and overclockers should pay attention to the MSI GeForce GTX 750 Ti TWIN FROZR: there is a wide choice here software and a module for switching between two BIOSes. All this will allow us to more effectively solve the tasks. And for those who are not inclined to experiment, we can offer the Gigabyte GeForce GTX 750 Ti - a reliable device from a renowned manufacturer with high pre-overclocking.
