In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390X XFX Double Dissipation Black 8GB Edition are massively better than the AMD Radeon R7 360 v2.

The R9 390X has a 40 MHz higher core clock speed and 128 more Texture Mapping Units than the R7 360. This results in the R9 390X providing 141.4 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 and 48 more Render Output Units than the R7 360. This results in the R9 390X providing 53 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 360 v2 and the Radeon R9 390X XFX Double Dissipation Black 8GB Edition were released at the same time, so are likely to be quite similar.

The R9 390X has 6144 MB more video memory than the R7 360, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 390X also has superior memory performance overall.

The R9 390X has 280 GB/sec greater memory bandwidth than the R7 360, which means that the memory performance of the R9 390X is massively better than the R7 360.

The Radeon R7 360 v2 has 768 Shader Processing Units and the Radeon R9 390X XFX Double Dissipation Black 8GB Edition has 2816. However, the actual shader performance of the R7 360 is 685 and the actual shader performance of the R9 390X is 2609. The R9 390X having 1924 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 390X delivers a massively smoother and more efficient experience when processing graphical data than the R7 360.

The Radeon R7 360 v2 requires 100 Watts to run and the Radeon R9 390X XFX Double Dissipation Black 8GB Edition requires 300 Watts. We would recommend a PSU with at least 500 Watts for the R7 360 and a PSU with at least 750 Watts for the R9 390X. The R9 390X requires 200 Watts more than the R7 360 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 R7 360.
