As NVIDIA readies its next-gen Kepler family of 28nm graphics cards, more and more details are starting to trickle out. Just yesterday, NVIDIA teased an Acer Ultrabook packing a mysterious new GT640M card based on the Kepler architecture. Today, we’re seeing information about the GTX 680 surfacing on multiple sites. China-based PCOnline posted specs it claims to have received from an internal NVIDIA source, including a 1,536 CUDA core count, 1,006MHz core frequency and 6Gbps memory. If it turns out to be true that it supports 2GB of 256-bit GDDR5 VRAM, that would fall short of AMD’s Radeon HD 7970, whose 384-bit bus serves 3GB of GDDR5 memory. However, the GTX 680 is also said to have a 195W power draw under load, which would be considerably lower than the 7970’s 300W. Then again, these specs don’t quite match what was previously rumored, so perhaps there’s still room for some surprises. No word on a release date or price, so for now you’ll have to make do with parsing those source links.
