Nvidia unveils the GeForce GTX 780 Ti

Doesn't the TITAN have a 837 MHz core clock? Even so, we get 1029 MHz core [5.93 TFLOPS] and 239 W TDP [24.8 GFLOPS/W] if the increase is proportional (probably won't be the case) and 933 MHz core [5.4 TFLOPS] and 245 W TDP [22.0 GFLOPS/W] if the increase is half that of the K20X to K6000 transition.

We can also look at memory speed. The M2070 has 3.132 Gbps memory and the 6000 has 3 Gbps memory, so somewhat close.

K20X to K6000: 5.2 Gbps to 6.0 Gbps

TITAN to 780 Ti (taking into account the difference between the M2070 and 6000): 6.0 Gbps to 7.2 Gbps [347 GB/s] (yeah right) proportional and 6.6 Gbps [317 GB/s] with half the increase.

It has a core clock of 837 but never runs at that speed, in gaming scenarios, is typically greater than 900mhz. Nonetheless, the 732mhz clock of k20x is constant. So in practice, there is an even larger difference between titan and k20x.

There's also one more things that going to result in power savings for gtx 780 ti. Versus the k6000, it only has 3gb of memory to address rather than 12gb. They is going to likely be balanced out by using 7ghz samsung chips, rather than 6ghz hynix chips(if these choose to use difference memory).

As I said early, I am not assuming the best case scenario where the increase is proportional, but even if just a little bit, like half the increase between k6000 and k20x, we still have very impressive increase for a respin of gk110. But this depends on a couple things, they actually use GK180 and the variability between bins on gk180.

But knowing Nvidia as of late, they are going to clock it low, so they can brag about the fantastic performance per watt. But card partners can pull the slack here. With cards like a lightning gtx 780 ti or classified, I would expect cards with 1000-1050mhz clocks if only the process improvement allows gtx 780 ti to clock as well as gtx 780's. This is a pretty low bar and I would expect them to at least match this.
