In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 5500M 4GB are significantly better than the AMD Radeon R9 M395X 4GB.

The RX 5500M has a 652 MHz higher core clock speed but 40 fewer Texture Mapping Units than the R9 M395X. The lower TMU count doesn't matter, though, as altogether the RX 5500M manages to provide 28.5 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 5500M has a 652 MHz higher core clock speed than the R9 M395X and the same number of Render Output Units. This results in the RX 5500M providing 20.9 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 5500M was released over three years more recently than the R9 M395X, and so the RX 5500M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the R9 M395X 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 RX 5500M 4GB and the Radeon R9 M395X 4GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 M395X has 160 GB/sec greater memory bandwidth than the RX 5500M, which means that the memory performance of the R9 M395X is massively better than the RX 5500M.

The Radeon RX 5500M 4GB has 1408 Shader Processing Units and the Radeon R9 M395X 4GB has 2048. However, the actual shader performance of the RX 5500M is 1506 and the actual shader performance of the R9 M395X is 1259. The RX 5500M having 247 better shader performance is not particularly notable, as altogether the R9 M395X performs better when taking into account other relevant data.

The RX 5500M transistor size technology is 21 nm (nanometers) smaller than the R9 M395X. This means that the RX 5500M is expected to run slightly cooler and achieve higher clock frequencies than the R9 M395X.

The Radeon RX 5500M 4GB requires 85 Watts to run and the Radeon R9 M395X 4GB requires 125 Watts. We would recommend a PSU with at least 450 Watts for the RX 5500M. The R9 M395X requires 40 Watts more than the RX 5500M to run. The difference is significant enough that the R9 M395X may have a slight adverse affect on your yearly electricity bills in comparison to the RX 5500M.
