In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are massively better than the AMD Radeon HD 7500G.

The GeForce 840M 2GB was released over a year more recently than the Radeon HD 7500G, 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 Radeon HD 7500G.

The GeForce 840M 2GB has 2048 MB video memory, but the Radeon HD 7500G 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 and the Radeon HD 7500G has 256. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the Radeon HD 7500G is 84. The GeForce 840M 2GB having 499 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 Radeon HD 7500G.

The GeForce 840M 2GB requires 33 Watts to run and the Radeon HD 7500G requires 17 Watts. The GeForce 840M 2GB requires 16 Watts more than the Radeon HD 7500G to run. The difference is not significant enough for the GeForce 840M 2GB to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7500G.

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.
Radeon HD 7500G is an integrated GPU on the entry-level ULV Trinity CPUs.
It's based on the 32nm Terascale 3 architecture and offers 256 Shader Processing Units, 16 TMUs and 8 ROPs. The memory interface will depend on whether or not the laptop's system RAM is dual channelled (128-bit if so, 64-bit, if not) and the operating memory clock can be up to 667MHz (max speed supported by the CPU). The central unit runs at 327MHz and will go up to 424MHz in Turbo Mode. Expect a TDP of up to 17 Watt.
Its performance is below Intel HD 4000 Graphics but is slightly above next in series - Radeon HD 7520G, despite the naming, due to the extra Shaders which prove useful in most of today's modern games.
Most of today's modern games will have to be played at the lowest settings, while extremely demanding games (e.g. Crysis 3) are most likely unplayable.
