Fudzilla have published specs of nVidia's GK104 GPU core, the successor to GF114 (GTX 560/560Ti). The first 28 nm Kepler GPU, that most sources are expecting in April, will most likely be known as the GTX 660, and will contain the GK 104 core. With an estimated 768 CUDA cores, this will have more than 2 TFLOPS raw performance, more than the current single-GPU flagship product, GTX 580.
We have seen various conflicting rumors around the expected dates of release for Kepler, and what order the various cores will be released in. The current report indicates that the dual-GPU GK110 will be the first to market, in April, followed by GK104, GK107 and GK108 (although this is still only rumors, albeit from a reputable source).
Fudzilla have reported that GK104 will have a 256-bit memory interface, and 2 GB maximum memory. TDP is expected to be around 225W. It is believed that it will have 768 CUDA cores, with a performance around 50% greater than the GTX 580. We hope to see official details soon, but for those of you waiting to see how Kepler will compare to Radeon HD 7000 GPUs, the figures so far indicate they will be competitive.
