In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 Crossfire are noticeably better than the Nvidia GeForce GTX 650 Ti Power Edition OC 1GB.

The GTX 650 Ti has a 193 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 7750. This results in the GTX 650 Ti providing 12.4 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 650 Ti has a 193 MHz higher core clock speed than the HD 7750, but the HD 7750 has 16 more Render Output Units than the GTX 650 Ti. As a result, the HD 7750 exhibits a 9.7 GPixel/s better Pixel Fill Rate than the GTX 650 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 Ti was released less than a year after the HD 7750, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7750 has 1024 MB more video memory than the GTX 650 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7750 also has superior memory performance overall.

The HD 7750 has 57.6 GB/sec greater memory bandwidth than the GTX 650 Ti, which means that the memory performance of the HD 7750 is much better than the GTX 650 Ti.

The Radeon HD 7750 Crossfire has 1024 Shader Processing Units and the GeForce GTX 650 Ti Power Edition OC 1GB has 768. However, the actual shader performance of the HD 7750 is 696 and the actual shader performance of the GTX 650 Ti is 763. The GTX 650 Ti having 67 better shader performance is not particularly notable, as altogether the HD 7750 performs better when taking into account other relevant data.

The Radeon HD 7750 Crossfire requires 110 Watts to run but there is no entry for the GeForce GTX 650 Ti Power Edition OC 1GB. We would recommend a PSU with at least 500 Watts for the HD 7750.
