In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670M 3GB are significantly better than the Nvidia GeForce 940MX 2GB.

The GeForce 940MX 2GB was released over three years more recently than the GTX 670M, and so the GeForce 940MX 2GB is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 670M when running the latest games.

The GTX 670M has 1024 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 670M also has superior memory performance overall.

The GTX 670M has 56 GB/sec greater memory bandwidth than the GeForce 940MX 2GB, which means that the memory performance of the GTX 670M is much better than the GeForce 940MX 2GB.

The GeForce 940MX 2GB has 384 Shader Processing Units and the GeForce GTX 670M 3GB has 336. However, the actual shader performance of the GeForce 940MX 2GB is 644 and the actual shader performance of the GTX 670M is 402. The GeForce 940MX 2GB having 242 better shader performance is not particularly notable, as altogether the GTX 670M performs better when taking into account other relevant data.

The GeForce 940MX 2GB transistor size technology is 12 nm (nanometers) smaller than the GTX 670M. This means that the GeForce 940MX 2GB is expected to run slightly cooler and achieve higher clock frequencies than the GTX 670M.

The GeForce 940MX 2GB requires 25 Watts to run and the GeForce GTX 670M 3GB requires 75 Watts. The GTX 670M requires 50 Watts more than the GeForce 940MX 2GB to run. The difference is significant enough that the GTX 670M may have a slight 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.

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.

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.

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.
GeForce GTX 670M 3GB is a high-end mobile GPU still based on the 2010 Fermi architecture.
It's based on the Fermi GF114 Core which offers 336 Shader Processing Units, 56 TMUs and 24 ROPs on a 192-bit memory interface of 3GB GDDR5 (which is a gimmick since this GPU does not benefit from a 2GB frame buffer, let alone 3GB). The central clock runs at 598MHz and the memory clock operates at 750MHz. Expect a power consumption of up to 75 Watts.
It's essentially a tweaked GeForce GTX 570M with a slightly higher clocked central unit that consumes the same power and so expect modern demanding games to be playable at 1080p with fluent frame rates (30+).
