In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260X v2 PowerColor OC 1GB Edition are significantly better than the AMD Radeon R7 250E.

The R7 260X has a 230 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon R7 250E. This results in the R7 260X providing 32.1 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 230 MHz higher core clock speed than the Radeon R7 250E and the same number of Render Output Units. This results in the R7 260X providing 3.7 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 Radeon R7 250E was released less than a year after the R7 260X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon R7 250E and the Radeon R7 260X v2 PowerColor OC 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R7 260X has 24 GB/sec greater memory bandwidth than the Radeon R7 250E, which means that the memory performance of the R7 260X is slightly better than the Radeon R7 250E.

The Radeon R7 250E has 512 Shader Processing Units and the Radeon R7 260X v2 PowerColor OC 1GB Edition has 896. However, the actual shader performance of the Radeon R7 250E is 348 and the actual shader performance of the R7 260X is 784. The R7 260X having 436 better shader performance and an altogether better performance when taking into account other relevant data means that the R7 260X delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon R7 250E.

The Radeon R7 250E requires 55 Watts to run and the Radeon R7 260X v2 PowerColor OC 1GB Edition requires 105 Watts. We would recommend a PSU with at least 400 Watts for the Radeon R7 250E and a PSU with at least 500 Watts for the R7 260X. The R7 260X requires 50 Watts more than the Radeon R7 250E to run. The difference is significant enough that the R7 260X may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon R7 250E.
