How well can the GeForce GT 640M run games
4 Jul 2020 - Graphics card reviewed

The GeForce GT 640M is a very low performing piece of gaming hardware and can probably only run indie system requirements. All games with system requirements of DirectX 11 or lower are met by this card.

How many years will the GeForce GT 640M graphics card play newly released games and how long until you should consider upgrading the GeForce GT 640M in your PC? Its upgrade time for the GeForce GT 640M, assuming you are a modern day gamer.

Whats a good PC graphics upgrade for the GeForce GT 640M? Upgrading this graphics card would have us consider the 20 Series GeForce RTX 2060 Mobile which is 908% more powerful. This upgrade choice can also run 831 games from the most demanding games today.

GeForce GT 640M Game Requirement Analysis

Overview
GeForce GT 640M 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 625MHz.


Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. 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 33W, it is suited for small laptops.


Performance
Gaming benchmarks indicate its performance is on average with the older GeForce GTX 465M.


System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 640M.
