In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 760M are significantly better than the Nvidia GeForce 840M 2GB.

The GeForce 840M 2GB has a 401 MHz higher core clock speed than the GeForce GTX 760M, but the GeForce GTX 760M has 40 more Texture Mapping Units than the GeForce 840M 2GB. As a result, the GeForce GTX 760M exhibits a 15.5 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 401 MHz higher core clock speed than the GeForce GTX 760M, but the GeForce GTX 760M has 8 more Render Output Units than the GeForce 840M 2GB. As a result, the GeForce GTX 760M exhibits a 1.8 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 less than a year after the GeForce GTX 760M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce 840M 2GB and the GeForce GTX 760M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GTX 760M has 48.1 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the GeForce GTX 760M is noticeably better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the GeForce GTX 760M has 768. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the GeForce GTX 760M is 505. The GeForce 840M 2GB having 78 better shader performance is not particularly notable, as altogether the GeForce GTX 760M performs better when taking into account other relevant data.

The GeForce 840M 2GB requires 33 Watts to run and the GeForce GTX 760M requires 55 Watts. The GeForce GTX 760M requires 22 Watts more than the GeForce 840M 2GB to run. The difference is not significant enough for the GeForce GTX 760M 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.

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 760M is a Performance Mobile Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK106-N14E-GL-A1 which has 4 Stream Multiprocessors activated and thus offers 768 Shader Processing Units, 64 TMUs and 16 ROPs. The Central Unit is initially clocked at 628MHz and goes up to 657MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 1002MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Kepler Boost, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 55W, it is suited for average sized laptops.

Performance
Despite being similar to GeForce GTX 650 Ti, GeForce GTX 760M is closer to the weaker GeForce GTX 650, due to being heavily underclocked.
Gaming benchmarks indicate its performance is on average with the older GeForce GTX 670M.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GTX 760M.
