To be known as the Geforce GTX 670 Ti
to a report over at Sweclockers, Nvidia is pushing its first Kepler based GPU for March launch, sometime after Cebit that kicks off on the 6th of March. The first in line should be the GK104 that will be branded as the GTX 670 Ti and should end up somewhere between the GTX 580 and HD 7950, performance wise.
As it was rumored earlier, the GK104 will bring a radically overhauled architecture and rumored specs include 1536 shaders, 128 TMUs, 32 ROPs and up to 2GB of GDDR5 memory paired up with a 256-bit memory interface. The GTX 670 Ti name doesn't come as a surprise as the GK104 is actually going to replace the GTX 560 Ti, but as always, until partners print the boxes, anything is possible.
The bad thing, for Nvidia at least, is that the flagship Kepler based cards are still months away and AMD will happily keep the performance crown for quite some time.
