In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 Ti Zotac OC 2GB Edition are marginally better than the AMD Radeon HD 7850 XFX Ultra OC Edition.

The GTX 750 Ti has a 71 MHz higher core clock speed than the HD 7850, but the HD 7850 has 24 more Texture Mapping Units than the GTX 750 Ti. As a result, the HD 7850 exhibits a 20.6 GTexel/s better Texture Fill Rate than the GTX 750 Ti. 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 Ti has a 71 MHz higher core clock speed than the HD 7850, but the HD 7850 has 16 more Render Output Units than the GTX 750 Ti. As a result, the HD 7850 exhibits a 14.5 GPixel/s better Pixel Fill Rate than the GTX 750 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 Ti was released over a year more recently than the HD 7850, and so the GTX 750 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7850.

The GTX 750 Ti has 1024 MB more video memory than the HD 7850, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 7850 has 67.2 GB/sec greater memory bandwidth than the GTX 750 Ti, which means that the memory performance of the HD 7850 is much better than the GTX 750 Ti.

The GeForce GTX 750 Ti Zotac OC 2GB Edition has 640 Shader Processing Units and the Radeon HD 7850 XFX Ultra OC Edition has 1024. However, the actual shader performance of the GTX 750 Ti is 971 and the actual shader performance of the HD 7850 is 849. The GTX 750 Ti having 122 better shader performance is not particularly notable, as altogether the HD 7850 performs better when taking into account other relevant data.

The GeForce GTX 750 Ti Zotac OC 2GB Edition requires 60 Watts to run but there is no entry for the Radeon HD 7850 XFX Ultra OC Edition. We would recommend a PSU with at least 400 Watts for the GTX 750 Ti and a PSU with at least 500 Watts for the HD 7850. The HD 7850 has been recommended a PSU with 100 Watts more than the GTX 750 Ti. The difference is significant enough that the HD 7850 may have an adverse affect on your yearly electricity bills in comparison to the GTX 750 Ti.
