In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640M LE are significantly better than the Intel HD Graphics Mobile (Broadwell).

The GT 640M has a 200 MHz higher core clock speed and 28 more Texture Mapping Units than the Graphics Mobile. This results in the GT 640M providing 14.8 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 GT 640M has a 200 MHz higher core clock speed and 14 more Render Output Units than the Graphics Mobile. This results in the GT 640M providing 7.4 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 Graphics Mobile was released over three years more recently than the GT 640M, and so the Graphics Mobile is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GT 640M when running the latest games.

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

The HD Graphics Mobile (Broadwell) has 12 Shader Processing Units and the GeForce GT 640M LE has 384. However, the actual shader performance of the Graphics Mobile is 10 and the actual shader performance of the GT 640M is 192. The GT 640M having 182 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 640M delivers a slightly smoother and more efficient experience when processing graphical data than the Graphics Mobile.

The Graphics Mobile transistor size technology is 6 nm (nanometers) smaller than the GT 640M. This means that the Graphics Mobile is expected to run very slightly cooler and achieve higher clock frequencies than the GT 640M.

The HD Graphics Mobile (Broadwell) requires 4 Watts to run and the GeForce GT 640M LE requires 20 Watts. The GT 640M requires 16 Watts more than the Graphics Mobile to run. The difference is not significant enough for the GT 640M to have a noticeably larger impact on your yearly electricity bills than the Graphics Mobile.

GPU Mini Review

Mini ReviewIntel HD Graphics Mobile (Broadwell) are integrated graphics in the budget Celeron and Pentium Broadwell Mobile processors.
Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface.
Best case scenario, the Intel HD Graphics Mobile (Broadwell) performs on par with Intel HD 4000 Graphics and so most modern demanding games will not be playable. Less graphically intense games will be playable at lower graphics settings.
Overview
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.
