In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are massively better than the Nvidia GeForce 8800M GT.

The GeForce 8800M GT has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GeForce 840M 2GB was released over three years more recently than the GeForce 8800M GT, 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 GeForce 8800M GT when running the latest games.

The GeForce 840M 2GB has 2048 MB video memory, but the GeForce 8800M GT does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 840M 2GB has 384 Shader Processing Units but the GeForce 8800M GT does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 840M 2GB requires 33 Watts to run but there is no entry for the GeForce 8800M GT.

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.
This card does not exist. We leave it here to let people know
The GeForce 8 Series, a computer graphics processing unit, is the eighth generation of NVIDIA's GeForce line. The third major GPU architecture developed at NVIDIA, the GeForce 8 represents the company's first unified shader architecture. It competed primarily against ATI's Radeon HD 2000-series cards.
There has been, at times, controversy over the naming of GeForce 8 series chips, including due to previous-generation chips being repackaged with minor changes (or possibly none at all) with the new names implying they are derived from the newly-introduced GPU chip design featured by the flagship products.
