Do the studio 15 throttle?

Probably why Apple refused to even accept and use 45nm Core i5 and Core i7 in their MacBook Pros.

Nah, apple isn't using the i7s because battery life stinks. And because there is huge competition in the i7 space, and they won't compete on price.

They're not using the i5s (yet) because they were only released a month ago.

Don't worry, they'll get around to it. Maybe they're just trying to clear old stock - quite a move, but hey ... it's apple.

Iwas meaning like the same problem as the xps line?

No. the XPS line isn't getting enough juice to run at full speed, the studio 15s have bad thermal design and the i7/i5s won't use turbo boost (and will even downclock) if they don't have thermal headroom. The power adapter for the XPS line doesn't provide enough power to run everything at full load, so the processor will drop into a lower clock. At least, that's the word from the Studio XPS 16 discussion...

If they are well cooled, then they'll run as fast as they can. The i7 is a beast.
