In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 840M 2GB are very slightly better than the AMD Radeon R7 8800P.

The GeForce 840M 2GB has a 229 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon R7 8800P. This results in the GeForce 840M 2GB providing 5.5 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 229 MHz higher core clock speed than the Radeon R7 8800P and the same number of Render Output Units. This results in the GeForce 840M 2GB providing 1.8 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 Radeon R7 8800P was released over a year more recently than the GeForce 840M 2GB, and so the Radeon R7 8800P is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 840M 2GB.

The GeForce 840M 2GB has 2048 MB video memory, but the Radeon R7 8800P does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the Radeon R7 8800P and the GeForce 840M 2GB have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce 840M 2GB is 583 and by the Radeon R7 8800P is 583. Knowing that the shader performance of the GeForce 840M 2GB is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R7 8800P requires 15 Watts to run and the GeForce 840M 2GB requires 33 Watts. The GeForce 840M 2GB requires 18 Watts more than the Radeon R7 8800P 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 R7 8800P.

GPU Mini Review

Mini ReviewOverview
Radeon R7 8800P is an Integrated Graphics Card in the APU FX-8800P Quad-Core Processor.

GPU
The Central Unit Runs at 800MHz.

Memory
The GPU also Shares the System's RAM which varies from laptop to laptop. Typically, the GPU reserves 1GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on the at which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 1067MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Performance
Benchmarks Indicate Performance around of a Dedicated GeForce 920M.

System Suggestions
We recommend 4GB of RAM for a system with Radeon R7 8800P.
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.
