In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 EVGA FTW+ 4GB Edition SLI are noticeably better than the Nvidia GeForce GTX 770 Palit JetStream 2GB 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 160.2 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 EVGA FTW+ 4GB Edition SLI has 1344 Shader Processing Units and the GeForce GTX 770 Palit JetStream 2GB Edition has 1536. However, the actual shader performance of the GTX 670 is 1457 and the actual shader performance of the GTX 770 is 1846. The GTX 770 having 389 better shader performance is not particularly notable, as altogether the GTX 670 performs better when taking into account other relevant data.

The GeForce GTX 670 EVGA FTW+ 4GB Edition SLI requires 340 Watts to run but there is no entry for the GeForce GTX 770 Palit JetStream 2GB Edition. We would recommend a PSU with at least 650 Watts for the GTX 670 and a PSU with at least 550 Watts for the GTX 770. The GTX 670 has been recommended a PSU with 100 Watts more than the GTX 770. The difference is significant enough that the GTX 670 may have an adverse affect on your yearly electricity bills in comparison to the GTX 770.
