In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M485X 4GB are massively better than the Nvidia GeForce 940MX 2GB.

The GeForce 940MX 2GB has a 399 MHz higher core clock speed than the R9 M485X, but the R9 M485X has 104 more Texture Mapping Units than the GeForce 940MX 2GB. As a result, the R9 M485X exhibits a 65.6 GTexel/s better Texture Fill Rate than the GeForce 940MX 2GB. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce 940MX 2GB has a 399 MHz higher core clock speed than the R9 M485X, but the R9 M485X has 24 more Render Output Units than the GeForce 940MX 2GB. As a result, the R9 M485X exhibits a 14.1 GPixel/s better Pixel Fill Rate than the GeForce 940MX 2GB. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 M485X was released less than a year after the GeForce 940MX 2GB, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The R9 M485X 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 R9 M485X also has superior memory performance overall.

The R9 M485X has 144 GB/sec greater memory bandwidth than the GeForce 940MX 2GB, which means that the memory performance of the R9 M485X is massively better than the GeForce 940MX 2GB.

The Radeon R9 M485X 4GB has 2048 Shader Processing Units and the GeForce 940MX 2GB has 384. However, the actual shader performance of the R9 M485X is 1259 and the actual shader performance of the GeForce 940MX 2GB is 644. The R9 M485X having 615 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M485X delivers a massively smoother and more efficient experience when processing graphical data than the GeForce 940MX 2GB.

The Radeon R9 M485X 4GB requires 125 Watts to run and the GeForce 940MX 2GB requires 25 Watts. The R9 M485X requires 100 Watts more than the GeForce 940MX 2GB to run. The difference is significant enough that the R9 M485X may have an adverse affect on your yearly electricity bills in comparison to the GeForce 940MX 2GB.

GPU Mini Review

Mini ReviewOverview
Radeon R9 M485X 4GB is a Performance Mobile Graphics Card based on the second revision of the Graphics Core Next Architecture (CGN).

Architecture
Radeon R9 M485X 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 M485X 4GB is a Direct Rebrand of Radeon R9 M395X 4GB.
Performance is Comparable to the desktop Radeon R9 280. Therefore, even GeForce GTX 970M is still faster.

System Suggestions
Radeon R9 M485X 4GB is best suited for resolutions up to and including 1920x1080. We recommend a Strong 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
GeForce 940MX 2GB Features a GPU Codenamed GM108-N16S-GTR which is a First Gen Maxwell GPU and is identical to the GM108-N16S-GT-S used on GeForce 940M but with the addition of GDDR5 Support.
GM108-N16S-GTR has 3 Compute Units Unlocked and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs.

GPU
The Central Unit is Clocked at 1122Hz and goes up to 1242MHz, in Turbo Mode.

Memory: Speed
The GPU is equipped with DDR3 and Accesses the Frame Buffer through a 64-bit Memory Interface. The Memory Clock Operates at 1001MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB.

Power Consumption
With a rated board TDP of 25W, it is suited for small and medium sized laptops.

Performance
Equipped with DDR3, GeForce GT 940MX is only slightly faster than GeForce GT 940M.

System Suggestions
GeForce 940MX 2GB is best suited for resolutions up to and including 1366x768. We Recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance.
