In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M395X 4GB are very slightly better than the AMD Radeon RX 540X 4GB Mobile.

The RX 540X has a 401 MHz higher core clock speed than the R9 M395X, but the R9 M395X has 96 more Texture Mapping Units than the RX 540X. As a result, the R9 M395X exhibits a 56.5 GTexel/s better Texture Fill Rate than the RX 540X. 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 401 MHz higher core clock speed than the R9 M395X, but the R9 M395X has 16 more Render Output Units than the RX 540X. As a result, the R9 M395X exhibits a 5.1 GPixel/s better Pixel Fill Rate than the RX 540X. 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 M395X, 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 M395X.

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 540X 4GB Mobile 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 540X, which means that the memory performance of the R9 M395X is massively better than the RX 540X.

The Radeon RX 540X 4GB Mobile has 512 Shader Processing Units and the Radeon R9 M395X 4GB has 2048. However, the actual shader performance of the RX 540X is 624 and the actual shader performance of the R9 M395X is 1259. The R9 M395X having 635 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M395X delivers a massively smoother and more efficient experience when processing graphical data than the RX 540X.

The RX 540X transistor size technology is 14 nm (nanometers) smaller than the R9 M395X. This means that the RX 540X is expected to run slightly cooler and achieve higher clock frequencies than the R9 M395X.

The Radeon RX 540X 4GB Mobile requires 50 Watts to run and the Radeon R9 M395X 4GB requires 125 Watts. We would recommend a PSU with at least 350 Watts for the RX 540X. The R9 M395X requires 75 Watts more than the RX 540X to run. The difference is significant enough that the R9 M395X may have an adverse affect on your yearly electricity bills in comparison to the RX 540X.

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 4GB 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.

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

Memory
The GPU accesses a 4GB 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.

Performance
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 1080p screen res and expect around 45+FPS. Performance is exactly the same as the Radeon RX 540.

System Suggestions
Radeon RX 540 4GB is best suited for resolutions up to and including 1600x900. We recommend a Performance Processor and 8GB of RAM for Optimal Performance.
Overview
Radeon R9 M395X 4GB is a High-End Mobile Graphics Card based on the second revision of the Graphics Core Next Architecture (CGN).

Architecture
Radeon R9 M395X 4GB Features a GPU Codenamed Amethyst XT which is a Third Gen GCN GPU and is identical to the Tonga XT GPU used on the Desktop Radeon R9 380X.
Amethyst XT has 32 Compute Units Unlocked and thus offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs.

GPU
The Central Unit is Clocked at 723MHz.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 256-bit Memory Interface. The Memory Clock Operates at 1250MHz.

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 125W, it is suited for very large laptops.

Performance
Radeon R9 M395X 4GB is a Direct Rebrand of Radeon R9 M295X 4GB.
Performance is Comparable to the desktop Radeon R9 280. Therefore, even GeForce GTX 970M is still faster.

System Suggestions
Radeon R9 M395X 4GB is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
