In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640M LE are marginally better than the AMD Radeon HD 8610G.

The Radeon HD 8610G has a 33 MHz higher core clock speed than the GT 640M, but the GT 640M has 8 more Texture Mapping Units than the Radeon HD 8610G. As a result, the GT 640M exhibits a 3.2 GTexel/s better Texture Fill Rate than the Radeon HD 8610G. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 8610G has a 33 MHz higher core clock speed than the GT 640M, but the GT 640M has 8 more Render Output Units than the Radeon HD 8610G. As a result, the GT 640M exhibits a 3.7 GPixel/s better Pixel Fill Rate than the Radeon HD 8610G. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 8610G was released over a year more recently than the GT 640M, and so the Radeon HD 8610G is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 640M.

The GT 640M has 1024 MB video memory, but the Radeon HD 8610G does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the GeForce GT 640M LE and the Radeon HD 8610G have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the Radeon HD 8610G is 240 and by the GT 640M is 240. Knowing that the shader performance of the Radeon HD 8610G is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GT 640M transistor size technology is 4 nm (nanometers) smaller than the Radeon HD 8610G. This means that the GT 640M is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon HD 8610G. While they exhibit similar graphical performance, the GT 640M should consume less power than the Radeon HD 8610G.

The GeForce GT 640M LE requires 20 Watts to run and the Radeon HD 8610G requires 25 Watts. The Radeon HD 8610G requires 5 Watts more than the GT 640M to run. The difference is not significant enough for the Radeon HD 8610G to have a noticeably larger impact on your yearly electricity bills than the GT 640M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 640M LE is a Middle-Class 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 GK107 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 500MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

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

Power Consumption
With a rated board TDP of 20W, it is suited for small laptops.

Performance
Gaming benchmarks indicate its performance is on average with the older GeForce GT 555M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 640M LE.
Radeon HD 8610G is an integrated mobile GPU, first seen on the ultra low-voltage APU A10-5745M, based on the 32nm, Terascale 3 architecture.
It offer 384 Shader Processing Units, 24 TMUs and 8 ROPs, on a DDR3 memory interface of either a 128-bit bus width, if the laptop system RAM's is dual-channelled, or a 64-bit bus width, if not. The central units runs at 533MHz and goes up to 626MHz, in Turbo Mode. The memory clock can operate up to 667MHz, as the max memory supported by the CPU is DDR3-1333.
Its performance depends heavily on whether or not the memory is dual-channelled. Benchmarks put its performance on level with today's middle-class GPUs such as GeForce GT 540M-GeForce GT 630M or Radeon HD 7650M/7670M. Therefore, modern demanding games can be played with medium detail.
