In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M275X are significantly better than the Nvidia GeForce 940MX 2GB.

The GeForce 940MX 2GB has a 222 MHz higher core clock speed than the Radeon R9 M275X, but the Radeon R9 M275X has 16 more Texture Mapping Units than the GeForce 940MX 2GB. As a result, the Radeon R9 M275X exhibits a 9.1 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 222 MHz higher core clock speed than the Radeon R9 M275X, but the Radeon R9 M275X has 8 more Render Output Units than the GeForce 940MX 2GB. As a result, the Radeon R9 M275X exhibits a 5.4 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 GeForce 940MX 2GB was released over a year more recently than the Radeon R9 M275X, and so the GeForce 940MX 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon R9 M275X.

The GeForce 940MX 2GB and the Radeon R9 M275X have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon R9 M275X has 48 GB/sec greater memory bandwidth than the GeForce 940MX 2GB, which means that the memory performance of the Radeon R9 M275X is noticeably better than the GeForce 940MX 2GB.

The GeForce 940MX 2GB has 384 Shader Processing Units and the Radeon R9 M275X has 640. However, the actual shader performance of the GeForce 940MX 2GB is 644 and the actual shader performance of the Radeon R9 M275X is 592. The GeForce 940MX 2GB having 52 better shader performance is not particularly notable, as altogether the Radeon R9 M275X performs better when taking into account other relevant data.

The GeForce 940MX 2GB requires 25 Watts to run and the Radeon R9 M275X requires 50 Watts. The Radeon R9 M275X requires 25 Watts more than the GeForce 940MX 2GB to run. The difference is not significant enough for the Radeon R9 M275X to have a noticeably larger impact on your yearly electricity bills than the GeForce 940MX 2GB.

GPU Mini Review

Mini ReviewOverview
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.
Radeon R9 M275X is a fast-middle-class-level graphics card based on the second revision of the Graphics Core Next architecture.
It offers a core codenamed Venus XTX that packs 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5. While the central unit runs at 900MHz and goes up to 925MHz, in Turbo Mode, the memory clock operates at 1000MHz. The regular version should offer 2GB of video memory but expect to see gimmicks of up to 4GB.
Its performance is practically identical to the old desktop Radeon HD 7770.
