C1E performance hit

[eddieck]

Does C1E cause any kind of performance hit, even if it's a millisecond more to do something? (Obviously if that were the case it's worth it to enable because of the power savings, but I'd still like to know.)

I know EIST definitely causes a very slight performance hit but C1E is totally different from EIST.

I have not seen any performance hit from C1E on my Q9550 or i7 860. The processor switches very fast to and from the advanced halt state.

No, C1E does not cause a performance hit.

Thanks. Going to enable it once I get my OC done.
