I enabled this on a 4-core sandy bridge (E3-1260L IIRC) and all four
cores suddenly grew a few % more clock cycles. But, it was on a server
whose fans are cranked high anyway, so the CPU temperature only grew a
degree or two.

I think Turbo Boost is boosting all cores that have work on it; it's
up to the thread/process scheduler to keep the thermal envelope such
that the overclocking works.
