So (K20X -> K40/K6000):
732 -> 797+
2688 -> 2880

I wouldn't expect more than 900 MHz base clock for the 780 Ti with 2880 shaders.
New comparison then, assuming 2880 CCs:

Code:
                               780 Ti (hypothetical)
           K20X  K6000  TITAN  Prop.  Half    225 W
      CCs  2688   2880   2688   2880  2880  2880  2880
     Core   732    797    837    911   874   857   804
   GFLOPS  3935   4590   4500   5249  5035  4934  4630
   Memory  5200   6000   6000   7228  6613  6794  6082
Bandwidth   208    288    288    347   317   326   292
      TDP   235    225    250    239   244   225   225
 GFLOPS/W  16.7   20.4   18.0   21.9  20.6  21.9  20.6

(Note that the M2070 has 3132 Mbps memory and the 6000 has 3000 Mbps memory.)
Interestingly, the ratio between the boost and base clocks of the K6000 (1.13) is about twice as large as the difference in many other Kepler cards with boost. Maybe it's due to the lower base clock?
