In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 Gainward 2GB Edition are noticeably better than the AMD Radeon HD 7770 Sapphire GHz OC Edition.

The HD 7770 has a 65 MHz higher core clock speed and 8 more Texture Mapping Units than the GTX 750. This results in the HD 7770 providing 11.3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7770 has a 65 MHz higher core clock speed than the GTX 750 and the same number of Render Output Units. This results in the HD 7770 providing 1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 was released over a year more recently than the HD 7770, and so the GTX 750 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7770.

The GTX 750 has 1024 MB more video memory than the HD 7770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 750 also has superior memory performance overall.

The GTX 750 has 1.6 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the GTX 750 is marginally better than the HD 7770.

The GeForce GTX 750 Gainward 2GB Edition has 512 Shader Processing Units and the Radeon HD 7770 Sapphire GHz OC Edition has 640. However, the actual shader performance of the GTX 750 is 804 and the actual shader performance of the HD 7770 is 626. The GTX 750 having 178 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 7770.

The GeForce GTX 750 Gainward 2GB Edition requires 55 Watts to run and the Radeon HD 7770 Sapphire GHz OC Edition requires 80 Watts. We would recommend a PSU with at least 400 Watts for the GTX 750 and a PSU with at least 450 Watts for the HD 7770. The HD 7770 requires 25 Watts more than the GTX 750 to run. The difference is not significant enough for the HD 7770 to have a noticeably larger impact on your yearly electricity bills than the GTX 750.

GPU Mini Review

Mini ReviewGeForce GTX 750 Gainward 2GB Edition is a special edition of the fast-middle-class GeForce GTX 750.

This edition comes with a custom cooling cooling solution which by itself will allow a slight performance boost, as GeForce GTX 750 benefits from the GPU Boost 2.0 technology.
Furthermore, it comes overclocked out of the box in the central unit that was raised from 1020MHz to 1085MHz, while the Turbo Boost is now of 1163MHz, instead of 1085MHz. The operating memory clock was increased to 1275MHz.
Further overclocking can be achieved easily, as the GPU has great OC potential.

Furthermore, the frame buffer was doubled to 2GB though this will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product.

Benchmarks indicate its performance is around 5.5% better than the reference NVIDIA GeForce GTX 750 and thus this card is slightly faster than Radeon R7 260X.
Radeon HD 7770 Sapphire GHz OC Edition is a special edition of the fast-middle-class Radeon HD 7770. See the standard version for more information about it.
The differences include increased memory and core clocks, from 1125MHz to 1250MHz and from 1000MHz to 1150MHz, respectively. A new quiet and efficient cooling system is also available.
Benchmarks indicate a 9,5% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) will run at the highest settings but not at extreme resolutions (due to the limited memory size).
