You mean 3.0? But no, it's not a useful technology, it's a stupid gimmick that just permits Intel to ship cheaper heatsinks. You're not getting free/bonus performance, you're maybe getting performance you should have already had out-of-the-box that you already paid for. Their CPUs are perfectly capable of reliably sustaining their all-core boost clocks, but the heat generated when doing so would require them to improve the box cooler. They guarantee the performance of the base clocks, not the turbo clocks. So as long as the stock heatsink can sustain base clocks, whatever extra performance you lose is not their problem. When all cores are capable of clocking higher but don't due to thermal issues, it's really no different than thermal throttling. If they wanted what was best for the customer, they wouldn't have "all-core turbo speeds" (and instead, use that speed as the base clock) and they'd ship a heatsink that wasn't made out of a pack of beer cans. This becomes unethical, in the sense that reviewers will keep the CPU in ideal conditions, whether that be cool and clean air, or whether that be an aftermarket heatsink. So even when they keep the CPU at "factory settings", it's going to run better than it will for the average joe, especially after joe has been using the computer for over a year and the stock heatsink is caked with dust. Like I said, I'm greatly in-favor of Turbo Boost, just not when all cores are boosted.
