Rumored NVIDIA GTX 680 specs surface online, photos prove it does indeed exist
As NVIDIA readies its 28nm family of Kepler 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, 195W TDP 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. 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.
