A peek at what's around the corner
Nvidia already owns the single-GPU performance crown, having plucked it back from the competition with the release of the GeForce GTX 780 Ti graphics card two months ago after AMD snatched it from atop the GeForce GTX Titan's head. Now that it's back where Nvidia feels it rightfully belongs, the GPU maker has no plans of letting it go any time soon and will defend its crown with the upcoming launch of the GeForce GTX Titan Black Edition and dual-GPU GeForce GTX 790 video cards.
According to VideoCardz , the updated Titan will flex the same GPU as the GTX 780 Ti but with higher double precision computing performance (more FP64 CUDA cores). It will also have 6GB of onboard GDDR5 memory, which is twice as much as the GTX 780 Ti, 2,880 CUDA cores, 240 TMUs, and 48 ROPs. No word on exactly when it will be released, just that it's likely coming sometime next month and is expected to cost around $1,000 MSRP.
The Titan Black Edition won't replace the GTX 780 Ti in performance, which is still the preferred card among gamers because of its price tag (it's several hundred dollars less than a Titan). However, those looking for a dual-GPU card will get their wish in March with the launch of the GTX 790.
VideoCardz warns that it wasn't able to verify the specs but believes it will ship with two 28nm GK110 GPus, two 2,496 CUDA-packed processors for 4,992 total, 416 total TMUs, 80 total ROPs, and 10GB of GDDR5 on a 320-bit bus. This one is also expected to retail for $1,000.
