In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 FTW 2GB Edition SLI are noticeably better than the Nvidia GeForce GTX 770 Zotac AMP! Edition.

The GTX 770 has a 144 MHz higher core clock speed than the GTX 670, but the GTX 670 has 96 more Texture Mapping Units than the GTX 770. As a result, the GTX 670 exhibits a 78.1 GTexel/s better Texture Fill Rate than the GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 770 has a 144 MHz higher core clock speed than the GTX 670, but the GTX 670 has 32 more Render Output Units than the GTX 770. As a result, the GTX 670 exhibits a 27.6 GPixel/s better Pixel Fill Rate than the GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 770 was released over a year more recently than the GTX 670, and so the GTX 770 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 670.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 670 has 2048 MB more video memory than the GTX 770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 670 also has superior memory performance overall.

The GTX 670 has 166.9 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the GTX 670 is massively better than the GTX 770.

The GeForce GTX 670 FTW 2GB Edition SLI has 2688 Shader Processing Units and the GeForce GTX 770 Zotac AMP! Edition has 1536. However, the actual shader performance of the GTX 670 is 2704 and the actual shader performance of the GTX 770 is 1846. The GTX 670 having 858 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 670 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 770.

The GeForce GTX 670 FTW 2GB Edition SLI requires 450 Watts to run but there is no entry for the GeForce GTX 770 Zotac AMP! Edition. We would recommend a PSU with at least 600 Watts for the GTX 770, but we do not have a recommended PSU wattage for the GTX 670.
