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

The R7 260X has a 145 MHz higher core clock speed and the same number of Texture Mapping Units as the R7 260X. This results in the R7 260X providing 8.1 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 R7 260X has a 145 MHz higher core clock speed than the R7 260X and the same number of Render Output Units. This results in the R7 260X providing 2.3 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the Radeon R7 260X v2 MSI OC v2 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 memory bandwidth of the Radeon R7 260X v2 MSI OC v2 2GB Edition and the Radeon R7 260X v2 PowerColor OC 1GB Edition are the same, which means the R7 260X and the R7 260X have equal limitations when it comes to graphical data transfer.

Both the Radeon R7 260X v2 MSI OC v2 2GB Edition and the Radeon R7 260X v2 PowerColor OC 1GB Edition have 896 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the R7 260X has 8.1 GTexel/s better Texture Fill Rate and 2.3 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the R7 260X takes the edge.

The Radeon R7 260X v2 MSI OC v2 2GB Edition requires 105 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 two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
