In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 540X 2GB Mobile are massively better than the AMD Radeon R9 M365X 4GB.

The RX 540X has a 499 MHz higher core clock speed but 8 fewer Texture Mapping Units than the R9 M365X. The lower TMU count doesn't matter, though, as altogether the RX 540X manages to provide 11 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 540X has a 499 MHz higher core clock speed than the R9 M365X and the same number of Render Output Units. This results in the RX 540X providing 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 RX 540X was released over a year more recently than the R9 M365X, and so the RX 540X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R9 M365X.

The R9 M365X has 2048 MB more video memory than the RX 540X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 M365X also has superior memory performance overall.

The R9 M365X has 64 GB/sec greater memory bandwidth than the RX 540X, which means that the memory performance of the R9 M365X is much better than the RX 540X.

The Radeon RX 540X 2GB Mobile has 512 Shader Processing Units and the Radeon R9 M365X 4GB has 640. However, the actual shader performance of the RX 540X is 624 and the actual shader performance of the R9 M365X is 340. The RX 540X having 284 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 540X delivers a marginally smoother and more efficient experience when processing graphical data than the R9 M365X.

The RX 540X transistor size technology is 14 nm (nanometers) smaller than the R9 M365X. This means that the RX 540X is expected to run slightly cooler and achieve higher clock frequencies than the R9 M365X.

The Radeon RX 540X 2GB Mobile requires 50 Watts to run and the Radeon R9 M365X 4GB requires 50 Watts. We would recommend a PSU with at least 350 Watts for the RX 540X. 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.

GPU Mini Review

Mini ReviewOverview
The new AMD Radeon RX 500X series are an OEM version of the current RX 500 series. The Radeon RX 540X 2GB Mobile is a Low to Middle-Class laptop Graphics Card based on the 4th Generation of the Graphics Core Next (GCN) Architecture. The specs of the Radeon RX 500X series graphics cards are identical to the standard Radeon RX 500 series.

It equips a GPU Codenamed Lexa Pro which has 14 Compute Units activated and thus 512 Shader Processing Units, 32 TMUs and 16 ROPs.

The GPU accesses a 2GB frame buffer of Fast GDDR5, through a 128-bit memory interface, while the Memory Clock Operates at 1500MHz.

Power Consumption
With a rated board TDP of 50W, it requires at least a 350W PSU and relies entirely on the PCI Slot for Power, meaning no Extra Connectors are required.

This graphics card was designed and marketed towards the competitive MOBA gamers with laptops. A light weight, small form factor GPU solution that offers mobility. The Radeon RX 54X0 4GB Mobile can play most modern games at medium graphics selection on a 900p screen res and expect around 45+FPS. Performance is exactly the same as the Radeon RX 540.

System Suggestions
Radeon RX 540 2GB is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Radeon R9 M365X 4GB is a Fast-Middle-Class Mobile Graphics Card based on the First Generation of the Graphics Core Next Architecture (GCN).

Radeon R9 M365X 4GB Features a GPU Codenamed Venus PRO which is a First Gen GCN GPU and is identical to the Cape GPU used on the Desktop Radeon R7 250X.
Venus PRO has 10 Compute Units Unlocked and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs.

The Central Unit is Clocked at 625MHz.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1000MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 4GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However, because the GPU itself is too weak to work under other circumstances in which 4GB of Memory are needed - such as 4K Gaming, a Large Frame Buffer is mostly a Gimmick.

Power Consumption
With a rated board TDP of 50W, it is suited for large laptops.

Radeon R9 M365X 4GB is a Direct Rebrand of Radeon R9 M265X.
Performance is Comparable to the Desktop Radeon R7 250.

System Suggestions
Radeon R9 M365X 4GB is best suited for resolutions up to and including 1600x900. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
