Well with speedstep kicking in on an overclock, yes I guess it would be. Also voltages are higher on an OC. But this is just what I think. Might be better off if someone knew for sure. Also depends on the CPU.
Depends on the CPUs.A 3.2GHz stock processor would be more efficient than a 3.2GHz overclock wouldn't it?
if you don't increase the voltages for your OC it's the same, I have a 25% OC with no voltage change, also, on Intel's, the cpu still steps down on idle relative to the OC, without an OC my cpu idles at 1.6GHZ, but with the OC it now idles at 2.0GHZ...
Speedstep is an option you can turn off.
of course you can, but why would you want to...? it would defeat the whole purpose of his question now wouldn't it...? his question was about cpu efficiency, you do understand that, right...? next you'll be telling me that there's an acronym for it and I can turn it on or off in the bios, wow, please enlighten me some more...
just general CPUsDepends on the CPUs.
If you compare a 6400+ X2 (the old one) and an overclocked 5400+ X2, although they'll be running at the same clock speed, the 6400+ still has a larger cache.
What CPUs are you talking about, exactly?
It depends on his definition of "efficient." It could mean anything from saving power to multitasking.
