In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 are massively better than the Nvidia GeForce 840M 2GB.

The GeForce 840M 2GB has a 219 MHz higher core clock speed than the GeForce GTX 560, but the GeForce GTX 560 has 32 more Texture Mapping Units than the GeForce 840M 2GB. As a result, the GeForce GTX 560 exhibits a 20.7 GTexel/s better Texture Fill Rate than the GeForce 840M 2GB. 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 219 MHz higher core clock speed than the GeForce GTX 560, but the GeForce GTX 560 has 24 more Render Output Units than the GeForce 840M 2GB. As a result, the GeForce GTX 560 exhibits a 17.7 GPixel/s better Pixel Fill Rate than the GeForce 840M 2GB. 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 a year more recently than the GeForce GTX 560, 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 GeForce GTX 560.

The GeForce 840M 2GB has 1024 MB more video memory than the GeForce GTX 560, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GTX 560 has superior memory performance.

The GeForce GTX 560 has 112.1 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the GeForce GTX 560 is massively better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the GeForce GTX 560 has 336. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the GeForce GTX 560 is 544. The GeForce 840M 2GB having 39 better shader performance is not particularly notable, as altogether the GeForce GTX 560 performs better when taking into account other relevant data.

The GeForce 840M 2GB transistor size technology is 12 nm (nanometers) smaller than the GeForce GTX 560. This means that the GeForce 840M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 560.

The GeForce 840M 2GB requires 33 Watts to run and the GeForce GTX 560 requires 150 Watts. We would recommend a PSU with at least 450 Watts for the GeForce GTX 560, but we do not have a recommended PSU wattage for the GeForce 840M 2GB. The GeForce GTX 560 requires 117 Watts more than the GeForce 840M 2GB to run. The difference is significant enough that the GeForce GTX 560 may have an adverse affect on your yearly electricity bills in comparison to 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.

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.
Overview
GeForce GTX 560 is a Performance Graphics Card based on the Fermi Architecture.

Architecture
The Fermi Architecture was first manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF114-325-A1 which has 7 Stream Multiprocessors activated and thus offers 336 Shader Processing Units, 56 TMUs and 32 ROPs. The Central Unit is clocked at 810MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1001Hz.

Power Consumption
With a rated board TDP of 150W, it requires at least a 450W PSU with two available 6-pin connectors.

Performance
GeForce GTX 560 competes with Radeon HD 6850 and proves to be around 10% faster.

System Suggestions
GeForce GTX 560 is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor and 8GB of RAM for Optimal Performance.
