In terms of overall gaming performance, the graphical capabilities of the AMD FirePro M8900 are marginally better than the Nvidia GeForce 840M 2GB.

The GeForce 840M 2GB was released over a year more recently than the FirePro M8900, 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 FirePro M8900.

The GeForce 840M 2GB and the FirePro M8900 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The FirePro M8900 has 99.2 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the FirePro M8900 is massively better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the FirePro M8900 has 960. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the FirePro M8900 is 424. The GeForce 840M 2GB having 159 better shader performance is not particularly notable, as altogether the FirePro M8900 performs better when taking into account other relevant data.

The GeForce 840M 2GB requires 33 Watts to run and the FirePro M8900 requires 75 Watts. The FirePro M8900 requires 42 Watts more than the GeForce 840M 2GB to run. The difference is significant enough that the FirePro M8900 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.
Professionals in the CAD (Computer Aided Design) and DCC (Digital Content Creation) industries need to be agile while being highly productive both in their office and on-the-go. AMD works with notebook vendors to provide workstation solutions to deliver advanced performance for applications across all industry segments. AMD FirePro™ professional graphics are compliant with the latest industry standards. Plus, AMD Catalyst™ professional graphics drivers are especially tuned to enable outstanding performance for many major CAD and DCC applications.
