In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 5500 8GB are significantly better than the AMD Radeon RX 460 2GB.

The RX 5500 has a 580 MHz higher core clock speed and 72 more Texture Mapping Units than the RX 460. This results in the RX 5500 providing 152.8 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 5500 has a 580 MHz higher core clock speed and 16 more Render Output Units than the RX 460. This results in the RX 5500 providing 36 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 5500 was released over three years more recently than the RX 460, and so the RX 5500 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the RX 460 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 RX 5500 has 6144 MB more video memory than the RX 460, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RX 5500 also has superior memory performance overall.

The RX 5500 has 224 GB/sec greater memory bandwidth than the RX 460, which means that the memory performance of the RX 5500 is massively better than the RX 460.

The Radeon RX 5500 8GB has 2048 Shader Processing Units and the Radeon RX 460 2GB has 896. However, the actual shader performance of the RX 5500 is 2456 and the actual shader performance of the RX 460 is 1075. The RX 5500 having 1381 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 5500 delivers a massively smoother and more efficient experience when processing graphical data than the RX 460.

The RX 5500 transistor size technology is 7 nm (nanometers) smaller than the RX 460. This means that the RX 5500 is expected to run very slightly cooler and achieve higher clock frequencies than the RX 460.

The Radeon RX 5500 8GB requires 120 Watts to run and the Radeon RX 460 2GB requires 75 Watts. We would recommend a PSU with at least 450 Watts for the RX 5500 and a PSU with at least 350 Watts for the RX 460. The RX 5500 requires 45 Watts more than the RX 460 to run. The difference is significant enough that the RX 5500 may have a slight adverse affect on your yearly electricity bills in comparison to the RX 460.
