GeForce 840M 4GB Game Requirement Analysis

Overview
GeForce 840M 4GB 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 4GB 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.


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 4GB.

it's really annoying that it's only 4 stars on 1366x768 resolution ..

it's for stars in 1920x1080, maybe 6 stars in 1366x768
