Maximum PC is reporting that NVIDIA is going to produce a whole line of TITAN cards.
There will be a higher end Titan Ultra:
This SKU will reportedly utilize all of the GK110’s 15 SMX clusters, giving it an edge over the regular Titan which has one cluster disabled with a total of 2,688 CUDA cores and 240 TMUs. As as result, the Titan Ultra will boast the full quota of 2880 shader cores and 256 texture units. Further, as opposed to the original’s 837 MHz clock speed and 206-Watt power appetite, the Ultra will have a 950 MHz clock speed and a 225W TDP
And a TITAN LE:
it will reportedly have 2496 CUDA cores, 208 TMUs, 40 ROPs, 320-bit DDR memory interface, 5 GB of GDDR5 and a 180-190W TDP
I would totally love an ULTRA TItan, as that is just a sick amount of CUDA.
