Rumors regarding NVIDIA's upcoming graphics cards bounce up and down. First it was a February release, then April, now rumors mention March again.
A report claims that NVIDIA is finally set to release the first Kepler GPU in March. As expected, first in line will be GK104 - to be branded as GeForce GTX 670 Ti. They peg the release date in March after Cebit 2012. This suggests a release some time between March 11th and March 31st. The GeForce GTX 670 Ti is vaguely indicated to have performance "better than GeForce GTX 580 and Radeon HD 7950", which implies average performance somewhere between HD 7950 and HD 7970.
Rumours suggest GK104 will bring a radically new architecture, with specifications including 1536 shaders, 128 TMU, 32 ROP and 2 GB 256-bit memory GDDR5. Core clock for the top bin, GTX 670 Ti, is expected to be around 950 MHz.
As the nomenclature suggests, GK104 / GTX 670 Ti is more of a successor to the GF114 / GTX 560 Ti. The flagship GTX 580 sucessor is at least half a year away, and will not be released till Q3 or Q4 2012. Till then, AMD is expected to hold on to the single GPU crown with Radeon HD 7970 with the GTX 670 Ti and HD 7950 following behind.
