In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are massively better than the AMD Mobility Radeon HD 560v.

The GeForce 840M 2GB has a 479 MHz higher core clock speed but 8 fewer Texture Mapping Units than the Radeon HD. The lower TMU count doesn't matter, though, as altogether the GeForce 840M 2GB manages to provide 7.1 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce 840M 2GB has a 479 MHz higher core clock speed than the Radeon HD and the same number of Render Output Units. This results in the GeForce 840M 2GB providing 3.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

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

The GeForce 840M 2GB has 1024 MB more video memory than the Radeon HD, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The Radeon HD has 9.6 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the Radeon HD is marginally better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the Mobility Radeon HD 560v has 320. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the Radeon HD is 114. The GeForce 840M 2GB having 469 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 840M 2GB delivers a slightly smoother and more efficient experience when processing graphical data than the Radeon HD.

The GeForce 840M 2GB transistor size technology is 27 nm (nanometers) smaller than the Radeon HD. This means that the GeForce 840M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD.

The GeForce 840M 2GB requires 33 Watts to run and the Mobility Radeon HD 560v requires 35 Watts. The Radeon HD requires 2 Watts more than the GeForce 840M 2GB to run. The difference is not significant enough for the Radeon HD to have a noticeably larger impact on your yearly electricity bills than 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.

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.

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.

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.

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.

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.
Mobility Radeon HD 560v is a middle-class GPU based on the 55nm, Terascale 1 architecture and therefore not related to other Mobility HD 5000 Series GPUs.
It's based on the M96 Core and offers 320 Shader Processing Units, 32 TMUs and 8 ROPs, on 128-bit memory interface of standard GDDR3. The central unit runs at 550MHz and the memory clock operates at up to 800MHz. It consumes no more than 35 Watt.
Benchmarks indicate modern demanding games of 2007-2010, such as Crysis, BF2 and Metro 2033 were playable at medium settings smoothly, using a 1024x768 resolution. Therefore, today's modern demanding games should be playable on the medium preset, using a 1024x768 resolution and extremely demanding modern games such as Crysis 3 on the lowest preset.
Its therefore an under-clocked Mobility Radeon HD 5165 and a renamed Mobility Radeon HD 4650. However, as based on the Terascale 1 architecture, DirectX 11 games aren't supported.
