Vigile writes "A new Acer Ultrabook, the Aspire Timeline Ultra M3, went on sale yesterday in Asia with a little surprise: NVIDIA's unreleased Kepler GPU inside. This is NVIDIA's first 28nm architecture and will compete against AMD's Radeon HD 7000 series of graphics cards. The version of Kepler found in the Acer Ultrabook only sports 384 CUDA cores and that is a noticeable jump up from 96 cores found in the 540M, and yet the GT 640M provides gaming performance comparable to the GT 555M. Plenty of details are still needed for a firm grasp of NVIDIA's latest GPU but showing off a high-powered discrete graphics solution in an Ultrabook indicates a step forward in performance per watt."
