Or... it could be something like this:
- Full GK110
- 320-bit memory bus with 5 GB of VRAM, with 6.5 Ghz or even 7 Ghz clockspeed
- Double precision disabled, hence lower TDP number while giving great gaming performance.
Could be, but the memory bus would need to be the same or larger than the 780/Titan.
I doubt they would invest time and money to include a wider memory bus as that isn't part of the original chip, the only other two options are:
- same memory bus, same amount of memory, making this a Titan, or better than Titan if the chip is fully enabled;
- in order to achieve a lower TDP, disabling one memory controller and reducing the VRAM to 5 GB (still ahead of the 290X and symbolically below the Titan), and make up for the loss of bandwidth by using the same 7 Ghz memory chips they are using with the GTX 770. If they could tune GK104 to operate at 7 Ghz, they can also tune GK110 to operate at 7 Ghz stock. This would possibly pose some problems when comparing overclocking results against the GTX 780, but if the chips on the GTX 780 Ti are 7 Ghz rated, they can probably overclock further than the ones on the GTX 780, meaning there won't be a memory bandwidth penalty for having a 320-bit memory bus instead of 384-bit.Edited by tpi2007 - 10/18/13 at 2:00pm
