In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980M 4GB are massively better than the Nvidia GeForce 940MX 2GB.

The GeForce 940MX 2GB has a 84 MHz higher core clock speed than the GTX 980M, but the GTX 980M has 72 more Texture Mapping Units than the GeForce 940MX 2GB. As a result, the GTX 980M exhibits a 72.7 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 84 MHz higher core clock speed than the GTX 980M, but the GTX 980M has 56 more Render Output Units than the GeForce 940MX 2GB. As a result, the GTX 980M exhibits a 57.4 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 GTX 980M, 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 GTX 980M.

The GTX 980M 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 GTX 980M also has superior memory performance overall.

The GTX 980M has 144.4 GB/sec greater memory bandwidth than the GeForce 940MX 2GB, which means that the memory performance of the GTX 980M is massively better than the GeForce 940MX 2GB.

The GeForce 940MX 2GB has 384 Shader Processing Units and the GeForce GTX 980M 4GB has 1536. However, the actual shader performance of the GeForce 940MX 2GB is 644 and the actual shader performance of the GTX 980M is 2337. The GTX 980M having 1693 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980M delivers a massively smoother and more efficient experience when processing graphical data than the GeForce 940MX 2GB.

The GeForce 940MX 2GB requires 25 Watts to run and the GeForce GTX 980M 4GB requires 100 Watts. The GTX 980M requires 75 Watts more than the GeForce 940MX 2GB to run. The difference is significant enough that the GTX 980M may have an adverse affect on your yearly electricity bills in comparison to 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.
Overview
GeForce GTX 980M 4GB is a high-end Mobile Graphics Card based on the second revision of the Maxwell architecture.

Architecture
The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.
The Second Revision of Maxwell also adds the VXGI (Voxel Global Illumination) Technology which makes scenes significantly more lifelike and believable as light interacts more realistically in the game environment and the MFAA Technology which provides the same effect as MSAA but at a much lower performance cost.

GPU
It equips a GPU codenamed GM204-N16E-GX-A2 which has 12 SM activated and thus offers 1536 Shader Processing Units, 96 TMUs and 64 ROPs. The central unit runs at 1038MHz and goes up to 1127MHz, in Turbo Mode.

Memory
The GPU accesses a 4GB frame buffer of fast GDDR5, through a 256-bit memory interface. The memory clock operates at 1253MHz. The size of the frame buffer is exaggerated and in no way adds extra performance.

Features
DirectX 12.0 Support (11.2 Hardware Default) and support for SLI, GameStream, G-SYNC, GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 100W, it will only be equipped in very large notebooks.

Performance
Benchmarks indicate its performance is over 30% faster than GeForce GTX 880M. Therefore, it should even surpass GeForce GTX 770 and be around as fast as desktop GeForce GTX 780.
GeForce GTX 980M is therefore the fastest mobile Graphics Card as of October 2014 and AMD's Radeon R9 M290X is beaten in over 40%.

System Suggestions
We recommend a very strong processor (Intel Core i7 Mobile Quad Core) and 8GB of RAM for a notebook with GeForce GTX 980M 8GB.
