In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260X XFX Double D 2GB Edition are very slightly better than the AMD Radeon R7 260X v2 PowerColor OC 1GB Edition.

The R7 260X has a 70 MHz higher core clock speed and the same number of Texture Mapping Units as the R7 260X. This results in the R7 260X providing 3.9 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 R7 260X has a 70 MHz higher core clock speed than the R7 260X and the same number of Render Output Units. This results in the R7 260X providing 1.1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the Radeon R7 260X XFX Double D 2GB Edition and the Radeon R7 260X v2 PowerColor OC 1GB Edition were released at the same time, so are likely to be quite similar.

The R7 260X 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 R7 260X also has superior memory performance overall.

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

Both the Radeon R7 260X XFX Double D 2GB Edition and the Radeon R7 260X v2 PowerColor OC 1GB Edition have 896 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the R7 260X is 838 and by the R7 260X is 784. Knowing that the shader performance of the R7 260X is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R7 260X XFX Double D 2GB Edition requires 115 Watts to run and the Radeon R7 260X v2 PowerColor OC 1GB Edition requires 105 Watts. We would recommend a PSU with at least 500 Watts for the R7 260X and a PSU with at least 500 Watts for the R7 260X. The R7 260X requires 10 Watts more than the R7 260X to run. The difference is not significant enough for the R7 260X to have a noticeably larger impact on your yearly electricity bills than the R7 260X.
