Yeah, no, I see holes in the sweclockers link that guru3d cites (Sure, if you think there are holes, you're going to find them [

]; if you read this stuff enough you can tell which ones need more thought).
Subtle error that most will miss:
"When NVIDIA released the GeForce GTX 680 in March 2012 it was clear that the new flagship was not based on the full version of the GPU Kepler (GK110). Instead, a cut-down version (GK104) to hold down the manufacturing costs"
GK100 was the base model that was never made and nVidia went for the cut-down GK104, not GK110, which would be a refresh (like GF100 in GTX480 and GF110 in GTX580 before).Assumption that a GeForce GK110 will have similar specs to Tesla K20-- that has never happened before. I were nVidia, I don't see benefit in taking those precious GK110 dies in cards that cost $3500 and sell them for even $900, unless I was absolutely certain that the sales volume would make up for lost profits. But high-end is never high-volume, and I don't know who is stupid enough to pay 80% more than a reference GTX680 only to gain 13% performance, which just about any GTX680 can reach overclocked to around 1140MHz base.
How do I get 13%? Simple math: (2496-cores x 702MHz base) ÷ (1536-cores x 1006MHz base) = 1.13. Because the frequency is low, the extra cores don't compensate much. GK110 would need 1GHz base to be worth it, but K20 uses 225W as is, so 1GHz base would push it up to 260W; add in the extra Vram to the suggested 6GB and raise the frequency, it wouldn't be able to close the performance gap between GTX680 and GTX690 while using the same power and costing as much as GTX690-- it's dead in the water.
The name Titan suggests a relation to the Cray Supercomputer that uses the GK110 Tesla cards-- what does that have to do with anything? I'm sure Cray and nVidia had their own codenames for their products before everything went public. I'm thinking those names got out and someone built this up.
Can someone explain the jump from Titan to Titanium other than spelling, Google Chrome translation errors and Greek mythology? It if far easier for me to believe that if a "GTX680 Ti" was to show up, it would reuse a GK104 die (leading to similar cost to produce a GTX680) and set the frequency higher by BIOS (cheapest route), a la HD7970 GHz Edition, than go for a GK110 die at a lower frequency.
In my mind, the only way rumor could possibly have meaning is going by EK's decision to make waterblocks for Tesla K20. What if they are thinking if a GeForce model uses the same PCB template, then they are ready before anyone else? That is a major gamble on EK's part, especially for a $3500 compute card; unless Cray buys 18,288 waterblocks.[

] Coincidentally, the EK blocks for Tesla K20 are to appear in February 2013 as well.
