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

The GeForce 940MX 2GB has a 524 MHz higher core clock speed than the GeForce GTX 670M, but the GeForce GTX 670M has 32 more Texture Mapping Units than the GeForce 940MX 2GB. As a result, the GeForce GTX 670M exhibits a 6.6 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 524 MHz higher core clock speed than the GeForce GTX 670M, but the GeForce GTX 670M has 16 more Render Output Units than the GeForce 940MX 2GB. As a result, the GeForce GTX 670M 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 three years more recently than the GeForce 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 GeForce GTX 670M when running the latest games.

The GeForce 940MX 2GB has 512 MB more video memory than the GeForce GTX 670M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GTX 670M has superior memory performance.

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

The GeForce 940MX 2GB has 384 Shader Processing Units and the GeForce GTX 670M has 336. However, the actual shader performance of the GeForce 940MX 2GB is 644 and the actual shader performance of the GeForce GTX 670M is 402. The GeForce 940MX 2GB having 242 better shader performance is not particularly notable, as altogether the GeForce 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 GeForce GTX 670M. This means that the GeForce 940MX 2GB is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 670M.

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

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 670M is a Performance Mobile Graphics Card based on the second revision of the Fermi Architecture.

Architecture
The Fermi Architecture was first manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF114 which has 7 Stream Multiprocessors activated and thus offers 336 Shader Processing Units, 56 TMUs and 24 ROPs. The Central Unit is clocked at 598MHz.

Memory
The GPU accesses a 1.5GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 750MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 75W, it is suited for large laptops.

Performance
GeForce GTX 670M is essentially a fast GeForce GTX 570M.
Gaming benchmarks put its performance somewhat above a desktop GeForce GTX 550 Ti.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GTX 670M.
