In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640 v3 Zotac 2GB Edition are noticeably better than the AMD Radeon HD 5670 Asus 1GB Edition.

The GT 640 has a 271 MHz higher core clock speed but 4 fewer Texture Mapping Units than the HD 5670. The lower TMU count doesn't matter, though, as altogether the GT 640 manages to provide 1.2 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 GT 640 has a 271 MHz higher core clock speed than the HD 5670 and the same number of Render Output Units. This results in the GT 640 providing 2.2 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 GT 640 was released over three years more recently than the HD 5670, and so the GT 640 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5670 when running the latest games.

The GT 640 has 1024 MB more video memory than the HD 5670, 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 5670 has 23.9 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the HD 5670 is slightly better than the GT 640.

The Radeon HD 5670 Asus 1GB Edition has 400 Shader Processing Units and the GeForce GT 640 v3 Zotac 2GB Edition has 384. However, the actual shader performance of the HD 5670 is 155 and the actual shader performance of the GT 640 is 402. The GT 640 having 247 better shader performance is not particularly notable, as altogether the HD 5670 performs better when taking into account other relevant data.

The GT 640 transistor size technology is 12 nm (nanometers) smaller than the HD 5670. This means that the GT 640 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5670.

The Radeon HD 5670 Asus 1GB Edition requires 64 Watts to run and the GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts. We would recommend a PSU with at least 400 Watts for the HD 5670 and a PSU with at least 350 Watts for the GT 640. The HD 5670 requires 15 Watts more than the GT 640 to run. The difference is not significant enough for the HD 5670 to have a noticeably larger impact on your yearly electricity bills than the GT 640.
