any real differnece between the SMIC and FMIC? or just really the location
from what i've read you'll experience less lag with the SMIC 
less lag you say??? Mmmm wonder why that is, so they both would give similar power gains
i'd imagine it's to do with the SMIC having a smaller volume, and thus taking a shorter period of time for the IC to fill, the problem is with a smaller volume the IC isn't going to be able to cool as much air as quickly as a bigger IC, causing the power to drop off quicker than one with a large volume / more efficient cooling, similar to how a smaller turbo spools up quicker, but doesn't pull for as long.
