We've been expecting GPUs based on Kepler — Nvidia's 28nm successor to the Fermi line — since the company first revealed the product's existence back in 2010. Things seem to be getting closer now, with Epic Games showing off a demo on Kepler hardware at this week's Game Developers Conference, and details on the first shipping commercial product starting to leak. Heise Online is reporting that several manufacturers at the CeBIT expo stated that the first Kepler-powered card will be the GeForce GTX 680. Powered by the GK104 core, the card will reportedly ship with 2GB of GDDR5 memory connected via a 256-bit memory controller, and will feature 1536 CUDA cores. A 4GB version will be available at a later date. The card is also said to feature a dynamic clocking feature, not dissimilar to Intel's Turbo Boost, that will allow the GPU to shift clock speeds depending on performance needs and temperature. The GTX 680 is expected in March, with ExtremeTech adding that the GPU will cost "upwards of $500." Cards based on the GK107 and GK110 cores are said to be coming in April and this summer, respectively.
