When NVIDIA took the wraps off its family of 28nm Kepler GPUs, it promised some mobile chips designed for Ultrabooks were soon to follow. Two and a half months later, we still haven't seen any laptops running the 600M series, save for the Acer Aspire M5, which isn't even on sale yet. Finally, though, the company's giving us a bit more: in advance of Computex, a computer-centric trade show about to be overrun by Ultrabooks, NVIDIA just spilled details on the GeForce GTX 680M. As the top-tier offering in the mobile Kepler lineup, it packs a 720MHz engine clock, 1,344 CUDA cores and a 256-bit memory bus powering up to 4GB of GDDR5 RAM. As a refresher, all of Kepler's GPUs make use of a new GPU Boost feature, which automatically increases the clock speed if the GPU isn't already taxed. Meanwhile, VSync promises smoother rendering, with fewer jagged edges. So which PC makers are planning on using this thing? Well, Clevo is on board, and NVIDIA says to expect some fresh models from MSI and Alienware, too. Stay tuned, folks.
