In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 460 2GB are significantly better than the AMD Radeon R7 360.
The RX 460 has a 40 MHz higher core clock speed and 8 more Texture Mapping Units than the Radeon R7 360. This results in the RX 460 providing 10.6 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 RX 460 has a 40 MHz higher core clock speed than the Radeon R7 360 and the same number of Render Output Units. This results in the RX 460 providing 0.6 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 RX 460 was released over a year more recently than the Radeon R7 360, and so the RX 460 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon R7 360.
The Radeon RX 460 2GB and the Radeon R7 360 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The Radeon R7 360 has 96 GB/sec greater memory bandwidth than the RX 460, which means that the memory performance of the Radeon R7 360 is massively better than the RX 460.
The Radeon RX 460 2GB has 896 Shader Processing Units and the Radeon R7 360 has 768. However, the actual shader performance of the RX 460 is 1075 and the actual shader performance of the Radeon R7 360 is 685. The RX 460 having 390 better shader performance is not particularly notable, as altogether the Radeon R7 360 performs better when taking into account other relevant data.
The RX 460 transistor size technology is 14 nm (nanometers) smaller than the Radeon R7 360. This means that the RX 460 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon R7 360.
The Radeon RX 460 2GB requires 75 Watts to run and the Radeon R7 360 requires 75 Watts. We would recommend a PSU with at least 350 Watts for the RX 460 and a PSU with at least 500 Watts for the Radeon R7 360. 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.
