In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 PNY 2GB Edition are massively better than the AMD Radeon HD 6790 XFX 1GB Edition.

The GTX 670 has a 75 MHz higher core clock speed and 72 more Texture Mapping Units than the HD 6790. This results in the GTX 670 providing 68.9 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 670 has a 75 MHz higher core clock speed and 16 more Render Output Units than the HD 6790. This results in the GTX 670 providing 15.9 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 GTX 670 was released over a year more recently than the HD 6790, and so the GTX 670 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6790.

The GTX 670 has 1024 MB more video memory than the HD 6790, 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 57.9 GB/sec greater memory bandwidth than the HD 6790, which means that the memory performance of the GTX 670 is much better than the HD 6790.

The GeForce GTX 670 PNY 2GB Edition has 1344 Shader Processing Units and the Radeon HD 6790 XFX 1GB Edition has 800. However, the actual shader performance of the GTX 670 is 1317 and the actual shader performance of the HD 6790 is 336. The GTX 670 having 981 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 HD 6790.

The GTX 670 transistor size technology is 12 nm (nanometers) smaller than the HD 6790. This means that the GTX 670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6790.

The GeForce GTX 670 PNY 2GB Edition requires 170 Watts to run but there is no entry for the Radeon HD 6790 XFX 1GB Edition. We would recommend a PSU with at least 500 Watts for the GTX 670 and a PSU with at least 500 Watts for the HD 6790. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
