Sure, but that would mean shorter lifetime and noisier console - but improvements in PSU/cooling would not really add much to cost, it's the yields of fully enabled GPU that needs to run on 1GHz.

2.5TFLOPS is 35% more then what PS4 currently has, plus 8 more TMUs for total of 80, both them and ROPs (along with triangle setup) on 25% higher clock - it's definitely not all about FLOPS...but that said, those 2 disabled CUs and anemic 800MHz clock are there cause they've decided to price PS4 at $399, they just couldn't risk with higher price.

Yields don't really have much to do with clocks, you just throw more voltage at the problem.

Sure, you can do that, yet there's a reason why they've decided to not try to go with 20CU GPU@1GHz (or even with 20CUs@ 850MHz, like 7970m), and my guess would be yields that would raise that $399 price.
