if you want the new 13-inch MacBook Pro Core i7 CPU to Turbo Boost his road north of that standard 2.7 GHz clock speed was expecting, guess we can stop your anticipation. Two separate reviews of the laptop are reporting the curious case of her Core i7-2620M processor overclocking itself does not automatically the way it should. Intel's dual-core chip is capable of a maximum speed of 3.4 GHz, but reviewers were not able to get it higher than the stock setting during test Apple's latest 13-incher.

High temperatures were identified (North of 90 C/194F) as the likely culprit, with Notebook Journal also found are throttled down to 798 MHz due to heat dissipation heat issues machine. PC Pro theory that Apple is the Turbo Boost functionality on this MBP model in order to keep your lap and your pride of being scalded by components melt intentionally disabled. That would make sense for us, and hey, it's still a fast machine, just don't Turbo fast.

Update: AnandTech the findings are inconsistent with the above, with Anand claim that "there is absolutely no funny business going on here, the dual-core 2.7 is allowed to hit its maximum frequencies. It seems that we have to keep digging to get to the bottom of this.


Update 2: We have confirmed with Apple, there are no specific limits for hardware or software to block the Turbo Boost feature, but we have also discovered, by less direct sources, that the company offers new low level software tools to cool configuration issues with the 2011 batch of laptops. Ergo, the speed limits that PC Pro and Notebook Journal encountered are caused by inadequate heat dissipation, which arguably is no less than an Apple command de-Turbo-restering disturbing.
