GeForce GT 640M Review
GeForce GT 640M is a middle-class mobile GPU based on the 28nm Kepler GK107 Core.
It offers 384 Shader Processing Units, 32 TMUs and 16 ROPs on a 128-bit memory interface of 2GB DDR3 (though GDDR5 is also supported but it most likely won't be used due to the increased cost and small performance boost). The central clock runs at 625MHz (709MHz in Turbo Mode) and the memory clock operates at 900MHz. Expect a power consumption of up to 32 Watt.
Benchmarks indicate its performance is quite average and that some modern demanding games are playable at high settings using a 720p resolution though small tweaks will be required to achieve more fluent (30+) FPS.
