Even if that was the case, I'll play devil's advocate and say: so what? This whole overclocking argument is simply grasping at straws, especially considering every card overclocks differently, regardless of whether it is an NVIDIA product or one from AMD.
With a few small overclocks of its own the 770 can surpass the 780 and easily retain its lead against AMD cards. Plus, this whole "1200MHz" thing is just preposterous.
I've reviewed EIGHT HD 7950 cards and I have achieved the follow stable core overclocks with voltage increases:
PowerColor Boost: 974MHz (1048MHz w/ fan @ 100%)
HIS ICEQ3: 1125MHz
WindForce OC: 1002MHz
MSI Twin Frozr OC: 998MHz
HIS Reference: 998MHz
AMD reference: 1011MHz
Sapphire Dual Fan OC: 1199MHz
XFX Black Edition: 1122MHz
So out of eight cards I had ONE that could consistently hit ~1200MHz with extra voltage and retain stability. With those statistics, I would say on average, a HD 7950 would OC to around 1050MHz which is far short of those rare instances where it would hit 1100MHz let alone 1200MHz or more.
Something else I want to bring up is the lack of linear scaling between clock speeds and performance. For example, if the core and memory speeds are increased by 20%, the impact upon framerates will be about 10% and at most 15%.
Therefore, bumping a HD 7950 Boost Edition's frequency to that mythical 1200MHz would net an average of ~12% better performance at high resolutions / detail settings, which certainly wouldn't allow it to consistently beat the GTX 770, let alone a card like the EVGA ACX SC. Anyone who claims otherwise is simply misstating results.
