In terms of overall gaming performance, the graphical capabilities of the GeForce 930MX 2GB and the GeForce 840M 2GB are equal.

The GeForce 840M 2GB has a 101 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce 930MX 2GB. This results in the GeForce 840M 2GB providing 2.4 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce 840M 2GB has a 101 MHz higher core clock speed than the GeForce 930MX 2GB and the same number of Render Output Units. This results in the GeForce 840M 2GB providing 0.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce 930MX 2GB was released over a year more recently than the GeForce 840M 2GB, and so the GeForce 930MX 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 840M 2GB.

The GeForce 930MX 2GB and the GeForce 840M 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 930MX 2GB has 24 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the GeForce 930MX 2GB is slightly better than the GeForce 840M 2GB.

Both the GeForce 930MX 2GB and the GeForce 840M 2GB have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 840M 2GB is 583 and by the GeForce 930MX 2GB is 583. Knowing that the shader performance of the GeForce 840M 2GB is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce 930MX 2GB requires 25 Watts to run and the GeForce 840M 2GB requires 33 Watts. The GeForce 840M 2GB requires 8 Watts more than the GeForce 930MX 2GB to run. The difference is not significant enough for the GeForce 840M 2GB to have a noticeably larger impact on your yearly electricity bills than the GeForce 930MX 2GB.

GPU Mini Review

Mini ReviewOverview
GeForce 930MX 2GB is a Middle-Class Mobile Graphics Card based on the Maxwell Architecture.

Architecture
GeForce 930MX 2GB Features a GPU Codenamed GM108-N16S-GMR which is a First Gen Maxwell GPU and is identical to the GM108-N16S-GM used on GeForce 930M but with the addition of GDDR5 Support.
GM108-N16S-GMR has 3 Compute Units Unlocked and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs.

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

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 64-bit Memory Interface. The Memory Clock Operates at 1250MHz.

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
Performance Not Known Yet.

System Suggestions
GeForce 930MX 2GB is best suited for resolutions up to and including 1600x900. We Recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance.
Overview
GeForce 840M 2GB is a Middle-Class Mobile Graphics Card based on the First Revision of the Maxwell architecture.

Architecture
The Maxwell architecture features many improvements and among them is the extremely large L2 Cache 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.

GPU
It equips a GPU codenamed GM108 which has 3 SM activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit runs at 1029MHz and goes up to 1124MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The Frame Buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 1001MHz.

Features
DirectX 11.2 Support (11.0 Hardware Default) and support for GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 33W, it will only be equipped in average sized notebooks.

Performance
Benchmarks indicate its performance is over 20% faster than the older GeForce GT 740M. Therefore, it should match GeForce GT 750M.

System Suggestions
We recommend a modest processor (Intel Core i5 Mobile) and 4GB of RAM for a notebook with GeForce 840M 2GB.
