News hit the wire that NVIDIA's GK104 GPU will be released next month as the GeForce GTX 670 Ti:
The GTX 670 Ti branding was first revealed by VR-Zone Chinese earlier this month and Sweclockers' sources - Taiwanese AIB partners - confirm the same. 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.
