http://www.engadget.com/2011/03/11/intel-turbo-boost-is-mia-on-
If you were expecting your new 13-inch MacBook Pro's Core i7 CPU to Turbo
Boost its way north of that default 2.7GHz clock speed, we ask that you
kindly discontinue your anticipation. Two separate reviews of the laptop are
reporting the curious case of its Core i7-2620M processor failing to
automatically overclock itself the way it should. Intel's dual-core chip is
capable of a maximum speed of 3.4GHz, but reviewers weren't able to get it
any higher than its stock setting while testing Apple's latest 13-incher.
High temperatures were identified (north of 90C / 194F) as the likely
culprit, with Notebook Journal also finding its machine throttled down to
798MHz due to heat dissipation issues. PC Pro theorizes that Apple
intentionally disabled the Turbo Boost functionality on this particular MBP
model in order to preserve your lap and your pride from being scalded by
melting components. That would make sense to us, and hey, it's still a fast
machine, just not Turbo fast. |

发帖数: 3409 | 8 散热的确是最大的问题啊。说实话我非常欣赏苹果的工业设计，拼命做到更轻更薄，
但也做出了过多的妥协。我可以想象：苹果的工程师一个又一个的设计方案被教主驳回，
并在教主的施压下做出了一个又一个的妥协。
我怀疑搭载Sandy Bridge的下一代MacBook Air会悲剧。
Core2 due也许是现在这个体型的MacBook Air能够承载的极限。

发帖数: 1387 | 10 Update: AnandTech's findings contradict the above, with Anand asserting that
"there's absolutely no funny business going on here, the dual-core 2.7 is
allowed to hit its maximum frequencies." Seems like we'll need to keep
digging to get to the bottom of this one.
Update 2: We've confirmed with Apple that there are no specific hardware or
software limits to block the Turbo Boost function, however we've also
discovered, through less direct sources, that the company is providing new
low level software tools to diagnose cooling issues with the 2011 batch of
laptops. Ergo, the speed limits that PC Pro and Notebook Journal encountered
might have been caused by inadequate heat dissipation, which arguably is no
less troubling than an Apple-mandated de-Turbo-fication. |

发帖数: 27968 | 13 应该是过热导致的
intel的turbo还是monitor芯片温度的，如果只turbo也可以更高
果壳这个不通风设计还是很反物理的
