GK110 w/ 1 CU shut down still consumes at least 20W more than a 7970GHz and gets trashed by it in anything compute. And isn't that much faster in a good number of games, heck, slower in DiRT Showdown, Tomb Raider (under some circumstances) and some other titles.
...and that's considering they had more than a year to get it right (LMAO @ the people saying they didn't release it because GK104 was "good enough").
nVidia might have marginally better power consumption in the high end, but that is all, nothing special about it. Looking at the lower end chips, AMD actually has a wider advantage over nVidia the other way around at higher TDP cards.
Why persist in spreading misinformation? This is from a previous thread about the GTX780:
From W1zzard's own
GTX Titan review you can find in the TPU website:
Power consumption:
7970 GHz beat by Titan in terms of power consumption efficiency in
every single scenario
Relative performance (average of every single 3D benchmark on every resolution):
GTX Titan beats the 7970GHz in every single resolution, now for Tomb Raider, this from W1zzard's review for the 7990:
The GTX Titan is faster than the 7970GHz in every resolution in that particular game, you may counter the 7990 is faster (and it is) but that's not even the point; dunno about DiRT showdown, but if what you say is true (W1zzard doesn't even test cards using that game) then it's probably the only scenario were the 7970GHz beats the Titan...
EDIT: Oh wait, I found these benchmarks using DiRT Showdown at Anand's:
Only in one scenario the 7970 "beats" Titan (if you call 0.9 FPS beating)
EDIT 2: as for the 7970 "trashing" Titan in compute performance, the theoretical max double precision performance (FP64) for 7970 is 1.08TFLOPs whereas Titan's is 1.3TFLOPs, but don't take it from me, this is (once again) from
Anandtech, an analysis of Titan's compute performance by Rahul Garg, a Ph D. specializing in the field of parallel computing and GPGPU technology:
Out of all compute tests performed, only in SystemCompute benchmark Titan is beat by 7970GHz, in all other benchmarks Titan leaves 7970 in the dust... I exactly wouldn't call that "trashing"
