In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7790 Sapphire OC Edition are marginally better than the AMD Radeon R7 260X v2 PowerColor OC 1GB Edition.

The HD 7790 has a 20 MHz higher core clock speed and the same number of Texture Mapping Units as the R7 260X. This results in the HD 7790 providing 1.1 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 HD 7790 has a 20 MHz higher core clock speed than the R7 260X and the same number of Render Output Units. This results in the HD 7790 providing 0.3 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 R7 260X was released less than a year after the HD 7790, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7790 has 1024 MB more video memory than the R7 260X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7790 also has superior memory performance overall.

The HD 7790 has 6.4 GB/sec greater memory bandwidth than the R7 260X, which means that the memory performance of the HD 7790 is marginally better than the R7 260X.

Both the Radeon R7 260X v2 PowerColor OC 1GB Edition and the Radeon HD 7790 Sapphire OC Edition have 896 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the HD 7790 is 941 and by the R7 260X is 941. Knowing that the shader performance of the HD 7790 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R7 260X v2 PowerColor OC 1GB Edition requires 105 Watts to run but there is no entry for the Radeon HD 7790 Sapphire OC Edition. We would recommend a PSU with at least 500 Watts for the R7 260X and a PSU with at least 500 Watts for the HD 7790. 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.

Benchmarks Indicate a 1% Performance Boost over the Reference Radeon R7 260X v2.
Radeon HD 7790 Sapphire OC Edition is a special edition of the performance Radeon HD 7790.
This edition comes with a cooling solution that uses a dual heatpipe system. It also comes overclocked out of the box in the core-clock to 1050MHz and on the memory clock to 1600MHz, though the latter might prove useless, as this card might not benefit from extra bandwidth.
Benchmarks indicate a 4% performance boost when compared to the reference card.
