Duke Nukem Forever is actually going to ship despite the absence of an apocalypse, and Nvidia wants to make sure you'll be able to play the long awaited follow-up on gaming notebooks. That's where Nvidia's new GeForce GTX 560M graphics chip comes in, one of two mobile GPUs Nvidia unwrapped at the Computex convention in Taiwan. As the more powerful of the two, Nvidia says "the GeForce GTX 560M and Nvidia Optimus mean gamers get 50 frames per second in Duke Nukem Forever and five hours of battery life in Microsoft Office," which translates into "real power and real portability."
Nvidia packed 192 CUDA cores into the GTX 560M. It has a core clockspeed of 775MHz, shaders clocked at 1559MHz, and GDDR5 memory clocked at 1250MHz on up to a 192-bit memory bus. Peak bandwidth is rated at up to 60GB/s. But what's really impressive here is that, for the first time, Nvidia is pairing its aforementioned Optimus technology with a GTX-level graphics chip.
The less powerful GeForce GT 520MX is aimed at thin-and-light notebooks and comes with 48 CUDA cores, 900MHz GPU clock, 1800MHz shader clock, and 900MHz memory clock on a 64-bit bus. Peak bandwidth is rated at up to 14.4GB/s.
