Accoriding to the latest roumors, Geforce Titan will hold 6GB of VRam, have a TDP of 235-250W and take up just 2 slots in your rig.
A, not so legit leak, showes Titan score X7377 on 3DMark 11, but the fishy part is that GPU-Z recognizes the Titan as GTX 780 which is just stupid.
The blurred out photo shows 12 memory banks on the front, an we can assume 12 on the back,so it reaches 6GB. In the middle, the only un-blurred detail is the massive core of te GPU saying; Taiwan, GK 110.
Further more, a price leak has been found, on a Scandinavian site, selling the GPU for 7000 kronas, which come up to around ~1000 US Dollars. This is very close te the first leaked price of 899$, but someone may get scared of 4 digit numbers.
First clocks have leaked: Asus Geforce Titan- Base 915 Boost: 1018/ Mem-6008Mhz
If the info is true, this card can beat a GTX 690 and the ROG ARES II like nothing. Nvidia just reserved the top once again, your move ATi!
