In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are massively better than the AMD Radeon R4 7000.

The GeForce 840M 2GB has a 496 MHz higher core clock speed and 16 more Texture Mapping Units than the Radeon R4 7000. This results in the GeForce 840M 2GB providing 20.4 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 496 MHz higher core clock speed and 4 more Render Output Units than the Radeon R4 7000. This results in the GeForce 840M 2GB providing 6.1 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 Radeon R4 7000 was released less than a year after the GeForce 840M 2GB, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce 840M 2GB has 2048 MB video memory, but the Radeon R4 7000 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon R4 7000 has 192 Shader Processing Units and the GeForce 840M 2GB has 384. However, the actual shader performance of the Radeon R4 7000 is 67 and the actual shader performance of the GeForce 840M 2GB is 583. The GeForce 840M 2GB having 516 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 R4 7000.

The Radeon R4 7000 requires 17 Watts to run and the GeForce 840M 2GB requires 33 Watts. The GeForce 840M 2GB requires 16 Watts more than the Radeon R4 7000 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 R4 7000.

GPU Mini Review

Mini ReviewRadeon R4 7000 is an integrated Graphics Card in the APU A6-7000.

It is based on the Graphics Core Next Architecture and offers 192 Shader Processing Units, 8 TMUs and 4 ROPs. While the central unit is set at 533MHz, the memory bus-width will depend on whether or not the system's RAM is dual-channeled and the operating memory clock, on its frequency. Thus, it can be either 64-bit or 128-bit and up to 800MHz.
The Graphics Card also shares the processor's L2 Cache of 1MB. Therefore, it reduces the need to resort to its memory bandwidth.

Overall, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance similar to an integrated Intel HD 4000.
The card is only suited for gaming below 720p and all modern demanding games can be played at least on low settings.
Overview
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.
