In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M365X 4GB are massively better than the AMD Radeon R4 7050B.

The R9 M365X has a 72 MHz higher core clock speed and 32 more Texture Mapping Units than the Radeon R4 7050B. This results in the R9 M365X providing 20.6 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 R9 M365X has a 72 MHz higher core clock speed and 12 more Render Output Units than the Radeon R4 7050B. This results in the R9 M365X providing 7.8 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 M365X was released less than a year after the Radeon R4 7050B, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The R9 M365X has 4096 MB video memory, but the Radeon R4 7050B does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon R9 M365X 4GB has 640 Shader Processing Units and the Radeon R4 7050B has 192. However, the actual shader performance of the R9 M365X is 340 and the actual shader performance of the Radeon R4 7050B is 69. The R9 M365X having 271 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M365X delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon R4 7050B.

The Radeon R9 M365X 4GB requires 50 Watts to run and the Radeon R4 7050B requires 17 Watts. The R9 M365X requires 33 Watts more than the Radeon R4 7050B to run. The difference is significant enough that the R9 M365X may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon R4 7050B.
