In any event, peak power consumption occurs only during 100% CPU
utilization (and that power consumption depends somewhat on the mix of
instructions, i.e., which portions of the CPU's processing logic is
active). When the CPU is idle, it's power consumption (and thus its
heat output) are much

Hi,
I think i fried my system (again ;) and was considering the config for
my next system.
When looking at the power consumptions of the multi-core CPU's, i was
wondering if it is possible to power-down one or more cores when the
system load does require them...
A quad core is nice, but needs
