In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 480M are noticeably better than the Nvidia GeForce 840M 2GB.

The GeForce 840M 2GB has a 604 MHz higher core clock speed but 20 fewer Texture Mapping Units than the GeForce GTX 480M. The lower TMU count doesn't matter, though, as altogether the GeForce 840M 2GB manages to provide 6 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 604 MHz higher core clock speed than the GeForce GTX 480M, but the GeForce GTX 480M has 24 more Render Output Units than the GeForce 840M 2GB. As a result, the GeForce GTX 480M exhibits a 5.4 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 three years more recently than the GeForce GTX 480M, 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 GeForce GTX 480M when running the latest games.

The GeForce 840M 2GB and the GeForce GTX 480M 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 480M has 60.8 GB/sec greater memory bandwidth than the GeForce 840M 2GB, which means that the memory performance of the GeForce GTX 480M is much better than the GeForce 840M 2GB.

The GeForce 840M 2GB has 384 Shader Processing Units and the GeForce GTX 480M has 352. However, the actual shader performance of the GeForce 840M 2GB is 583 and the actual shader performance of the GeForce GTX 480M is 299. The GeForce 840M 2GB having 284 better shader performance is not particularly notable, as altogether the GeForce GTX 480M 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 480M. This means that the GeForce 840M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 480M.

The GeForce 840M 2GB requires 33 Watts to run and the GeForce GTX 480M requires 100 Watts. The GeForce GTX 480M requires 67 Watts more than the GeForce 840M 2GB to run. The difference is significant enough that the GeForce GTX 480M 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.

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.
GeForce GTX 480M is a High-End Mobile Graphics Card based on the first revision of the Fermi 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.

It equips a GPU Codenamed Fermi GF100-N11E-GTX-A3 which has 11 Stream Multiprocessors activated and thus offers 352 Shader Processing Units, 44 TMUs and 32 ROPs. The Central Unit is clocked at 425MHz.

The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 600MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 100W, it is only suited for very large laptops.

Gaming benchmarks put its performance identical to a desktop GeForce GTS 450.

System Suggestions
We recommend a fast processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 480M.
