In a move by NVIDIA that could present enthusiasts with deep pockets more options in the high-end GPU segment, the company is planning not one, but two high-end graphics cards for this quarter (January to March). The company is planning to follow up its February launch of the GeForce GTX TITAN Black Edition with a dual-GPU card based on the GK110 silicon, presumably named "GeForce GTX 790." The card will be launched some time in March, and could help NVIDIA hold onto its own until it can make high-end GPUs on the teething next-generation 20 nm silicon fab process.

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.The GeForce GTX 790 is a whole different beast. Owing to electrical and thermal constraints inherent to placing two multi billion transistor GPUs next to each other, NVIDIA will deploy two cut-down GK110 chips. The duo will be faster than anything that was ever made to crunch pixels, if an application takes advantage of NVIDIA SLI. The ones that don't, will have to make do with a chip that's rumored to feature 2,496 CUDA cores, 208 TMUs, 40 ROPs, and a 320-bit wide memory interface, handling 5 GB of GDDR5 memory. In total, the card would hence feature 10 GB of memory.
