NVIDIA is said to be working on two new uber-high-end cards and both are reportedly slated for this quarter. TPU heard we may see the launch of the GeForce GTX Titan Black Edition in February, this model will replace the current Titan with a card that's not too different from the GTX 780 Ti in terms of core-configuration:
The GeForce GTX TITAN Black Edition replaces the GTX TITAN with a product that's not too different from the GTX 780 Ti in terms of core-configuration, but one that comes with 6 GB of memory, full double-precision floating point performance, and probably higher clock speeds. It offers the full complement of 2,880 CUDA cores, 240 TMUs, 48 ROPs, and a 384-bit wide GDDR5 memory interface. This card could displace the current GTX TITAN from its $999 price-point.
Sometime in March we can expect the GeForce GTX 790, this will be a new dual-GPU card that uses two cut-down GK110 chips with a total of 10GB GDDR5 memory. Each of the card's GPUs reportely has 2496 CUDA cores, 208 TMUs, 40 ROPS, and a 320-bit memory bus.
