In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390X PowerColor Devil 8GB Edition are marginally better than the AMD Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition.

The R9 390X has a 40 MHz higher core clock speed and the same number of Texture Mapping Units as the R9 390X. This results in the R9 390X providing 7 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 R9 390X has a 40 MHz higher core clock speed than the R9 390X and the same number of Render Output Units. This results in the R9 390X providing 2.6 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 R9 390X was released less than a year after the R9 390X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition and the Radeon R9 390X PowerColor Devil 8GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 390X has 6.4 GB/sec greater memory bandwidth than the R9 390X, which means that the memory performance of the R9 390X is marginally better than the R9 390X.

Both the Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition and the Radeon R9 390X PowerColor Devil 8GB Edition have 2816 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 R9 390X has 7 GTexel/s better Texture Fill Rate, 2.6 GPixel/s better Pixel Fill Rate, and 6.4 GB/sec greater memory bandwidth, so should have a marginally faster performance than the R9 390X.

The Radeon R9 390X Sapphire Nitro w/ Back Plate 8GB Edition requires 375 Watts to run and the Radeon R9 390X PowerColor Devil 8GB Edition requires 275 Watts. We would recommend a PSU with at least 750 Watts for the R9 390X and a PSU with at least 750 Watts for the R9 390X. The R9 390X requires 100 Watts more than the R9 390X to run. The difference is significant enough that the R9 390X may have an adverse affect on your yearly electricity bills in comparison to the R9 390X.
