I don't understand the obsession with all cores, although I can see why it would provide the highest numbers in a select few situations. I mean, beyond high scores in specific highly threaded applications, an extra few hundred MHz will have very little effect in computational work, and in games you'll find threads being limited to pretty low numbers on a regular basis. My point being, it would be much more interesting to see a processor do 6.0 GHz as its max turbo, that way you know you'll have the extra power in thread limited situations, which is usually when you need it the most. It's a bit like Intel releasing that 5.0 GHz all core special edition processor, which is not much use in pretty much any situation, other than appealing to a select few who seem to have an unhealthy fascination with equal frequencies on all cores. Also, let's not forget higher temps and unnecessary power usage, all when you could simply run much higher turbo clocks on pretty much the same voltage. Of course, the only draw back being you couldn't use load line calibration, which is far from ideal any way.
