In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are very slightly better than the Nvidia Quadro K3000M.

The GeForce 840M 2GB was released over a year more recently than the Quadro K3000M, and so the GeForce 840M 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Quadro K3000M.

The GeForce 840M 2GB and the Quadro K3000M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Quadro K3000M has 73.6 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the Quadro K3000M is much better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the Quadro K3000M has 576. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the Quadro K3000M is 377. The GeForce 840M 2GB having 206 better shader performance is not particularly notable, as altogether the Quadro K3000M performs better when taking into account other relevant data.

The GeForce 840M 2GB requires 33 Watts to run and the Quadro K3000M requires 75 Watts. The Quadro K3000M requires 42 Watts more than the GeForce 840M 2GB to run. The difference is significant enough that the Quadro K3000M may have a slight adverse affect on your yearly electricity bills in comparison to 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.
Quadro K3000M is a high-end business card based on the 28nm, Kepler architecture.
Technically the successor to the previous Quadro 3000M, it's based on the Kepler GK104 (despite the SPU count) and offers 576 Shader Processing Units, 48 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 600MHz and the memory clock operates at up to 700MHz.
Quadro K3000M's drivers are certified for professional applications only. Its gaming performance is slightly above GeForce GTX 660M.
