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.

This card was preinstalled on my laptop and I use it mostly for gaming. Some games (i.e AC4) show lag even on very low settings. I plan to play DA: Inquisition on my laptop. If I upgrade, what would be a good new GPU? Geforce 740m?

First of all, you can't upgrade a GPU on a laptop.
Secondly, AC4 shouldn't be lagging on this card. Check to see if your running it on Intel HD 4000, instead of the GT640M.

Some laptop manufacturers give the user the ability to upgrade, maybe he can.

Not recommended for lower tier cards (like this one) to be used for both graphics rendering and PhysX at the same time. Higher tier cards can do all by themselves, but best to to have sli setup and run PhysX entirely on 1 card, while the other do the rendering for optimal performance/quality.

I got this card with my laptop, pre-installed of course. I hadn't planned on using the laptop for gaming, mostly photography processing - photoshop, lightroom etc .. decided to give it a whirl with a few games and was pleasantly surprised.

I find this card very nice, for not-demanding games. I can as an example play Far Cry 3 on high quality…..Call of duty MW3 on High, and games like Crysis on Medium.
On demanding games I would recommend using low settings, or even adjust the resolution if neccesary

How will this card perform with an Intel Core I7 3630QM and 8Gb of ram and a screen of 1366x768? On games like L4D2,Far cry 3,Resident Evil 6,Dead Island…games like that but not very demanding ones? :O

Hi.
You have selected a desktop CPU and a laptop GPU. Which one is it? Desktop or Laptop? GT 640 2GB GDDR5 is already added.
