In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 EVGA Superclocked 1GB Edition are significantly better than the AMD Radeon HD 5770 512MB.

The GTX 750 has a 365 MHz higher core clock speed but 8 fewer Texture Mapping Units than the HD 5770. The lower TMU count doesn't matter, though, as altogether the GTX 750 manages to provide 4.9 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 GTX 750 has a 365 MHz higher core clock speed than the HD 5770 and the same number of Render Output Units. This results in the GTX 750 providing 5.8 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 three years more recently than the HD 5770, and so the GTX 750 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5770 when running the latest games.

The GTX 750 has 512 MB more video memory than the HD 5770, 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 3.4 GB/sec greater memory bandwidth than the HD 5770, which means that the memory performance of the GTX 750 is marginally better than the HD 5770.

The GeForce GTX 750 EVGA Superclocked 1GB Edition has 512 Shader Processing Units and the Radeon HD 5770 512MB has 800. However, the actual shader performance of the GTX 750 is 894 and the actual shader performance of the HD 5770 is 340. The GTX 750 having 554 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 5770.

The GTX 750 transistor size technology is 12 nm (nanometers) smaller than the HD 5770. This means that the GTX 750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5770.

The GeForce GTX 750 EVGA Superclocked 1GB Edition requires 55 Watts to run and the Radeon HD 5770 512MB requires 108 Watts. We would recommend a PSU with at least 300 Watts for the GTX 750 and a PSU with at least 450 Watts for the HD 5770. The HD 5770 requires 53 Watts more than the GTX 750 to run. The difference is significant enough that the HD 5770 may have an adverse affect on your yearly electricity bills in comparison to the GTX 750.
