GeForce GT 645M 2GB DDR3 Review
GeForce GT 645M 2GB DDR3 is a fast 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 and this GPU does not benefit from a 2GB frame buffer). The central clock runs at 710MHz and the memory clock operates at 900MHz. Expect a power consumption of up to 32 Watts.
Benchmarks indicate its performance is considerably higher than GT 640M and that most modern demanding games are playable at high settings using a 720p resolution though small tweaks will be required to achieve more fluent (30+) FPS.
