In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 540 4GB Mobile are massively better than the Nvidia GeForce 940MX 2GB.

The RX 540 has a 2 MHz higher core clock speed and 8 more Texture Mapping Units than the GeForce 940MX 2GB. This results in the RX 540 providing 9.1 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 540 has a 2 MHz higher core clock speed and 8 more Render Output Units than the GeForce 940MX 2GB. This results in the RX 540 providing 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 540 was released over a year more recently than the GeForce 940MX 2GB, and so the RX 540 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 940MX 2GB.

The RX 540 has 2048 MB more video memory than the GeForce 940MX 2GB, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RX 540 also has superior memory performance overall.

The GeForce 940MX 2GB has 16 GB/sec greater memory bandwidth than the RX 540, which means that the memory performance of the GeForce 940MX 2GB is slightly better than the RX 540.

The Radeon RX 540 4GB Mobile has 512 Shader Processing Units and the GeForce 940MX 2GB has 384. However, the actual shader performance of the RX 540 is 624 and the actual shader performance of the GeForce 940MX 2GB is 644. The GeForce 940MX 2GB having 20 better shader performance is not particularly notable, as altogether the RX 540 performs better when taking into account other relevant data.

The RX 540 transistor size technology is 14 nm (nanometers) smaller than the GeForce 940MX 2GB. This means that the RX 540 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 940MX 2GB.

The Radeon RX 540 4GB Mobile requires 50 Watts to run and the GeForce 940MX 2GB requires 25 Watts. We would recommend a PSU with at least 350 Watts for the RX 540. The RX 540 requires 25 Watts more than the GeForce 940MX 2GB to run. The difference is not significant enough for the RX 540 to have a noticeably larger impact on your yearly electricity bills than the GeForce 940MX 2GB.

GPU Mini Review

Mini ReviewOverview
The Radeon RX 540 4GB Mobile is a Low to Middle-Class laptop Graphics Card based on the 4th Generation of the Graphics Core Next (GCN) Architecture.

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 540 4GB Mobile can play most modern games at medium graphics selection on a 1080p screen res and expect around 45+FPS.

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
GeForce 940MX 2GB is a Middle-Class Mobile Graphics Card based on the Maxwell Architecture.

Architecture
