In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are massively better than the Nvidia NVS 5100M.

The GeForce 840M 2GB was released over three years more recently than the NVS 5100M, and so the GeForce 840M 2GB is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the NVS 5100M when running the latest games.

The GeForce 840M 2GB has 1024 MB more video memory than the NVS 5100M, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The NVS 5100M has 9.6 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the NVS 5100M is marginally better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the NVS 5100M has 48. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the NVS 5100M is 26. The GeForce 840M 2GB having 557 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 840M 2GB delivers a noticeably smoother and more efficient experience when processing graphical data than the NVS 5100M.

The GeForce 840M 2GB transistor size technology is 12 nm (nanometers) smaller than the NVS 5100M. This means that the GeForce 840M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the NVS 5100M.

The GeForce 840M 2GB requires 33 Watts to run and the NVS 5100M requires 35 Watts. The NVS 5100M requires 2 Watts more than the GeForce 840M 2GB to run. The difference is not significant enough for the NVS 5100M to have a noticeably larger impact on your yearly electricity bills than the GeForce 840M 2GB.

GPU Mini Review

Mini ReviewOverview
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.
NVS 5100M is an entry-level business card with support for special drivers that are certified for professional applications like Microsoft Office Suite, Hummingbird Exceed, Lotus Notes, etc. It's part of the NVS Mobile Series released by NVIDIA, in 2010/2011.
Though business cards have no driver support for games, some of them deliver astonishing performance (e.g. Quadro 6000, Tesla C2075). Considering the specifications the performance should be better yet similar to the middle-class GeForce 230M and therefore Very demanding games like Metro 2033 might be unplayable even at the lowest settings or only playable at the lowest resolution, which is unbearable, even to the casual gamer. Even old demanding games like Call of Duty 4: Modern Warfare require reduced settings smoothly.
