Nvidia has taken the wraps off its latest high-end graphics chips for notebooks at Computex. The new GeForce GTX 560M brings a welcome performance boost from the GTX 460M as well as improved battery life thanks to the company's Optimus graphics switching technology. Specs include 192 CUDA cores, with 1550MHz shader frequency, a 775MHz graphics clock, and 1250MHz memory frequency with either 1.5GB or 3GB of GDDR5 memory and a 192-bit bus. According to the company the new GTX 560M should enable the latest games to run at playable frame rates on a 1080p screen with maximum detail, minus antialiasing. So far Asus , MSI, Alienware, Toshiba and Clevo have all committed to new notebooks packing the new graphics processor, though as usual specific implementations are up to each manufacturer and it seems only Toshiba's Qosmio and Alienware's M17x will offer Optimus support.
