It looks like NVIDIA may be working on a second GK110-based consumer GPU to fill the gap between the marginally expensive GTX 680 and the ridiculously expensive GTX Titan released last month. With a $500 gap between the GTX 680 and GTX Titan, NVIDIA has a lot of wiggle room to squeeze another GPU in the lineup.
The video card is said to feature 13 of the 15 streaming multiprocessors that are built into the GK110 silicon. This means we would have 2,496 CUDA cores to do our gaming bidding. Combine that with 208 texture memory units, 40ROPs, a 320-bit memory interface, and 5GB of GDDR5 RAM and you end up with a fairly powerful card.
The rumored release date is somewhere between July and August of this year.
