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.
