Effects of Overclocking on CPU usage?

[HaMMuS]

I apologise if this is the wrong forum to ask this, but I have a couple of questions for all you CPU guru's out there.

If I have a CPU at stock, and perform some task on it that has 60% CPU usage, if I overclock it by 50% and perform the same task again will my CPU usage be lower?

Also how does windows gauge how much CPU is being used? Does it depend on the number of registers or pipelines in use or is it simpler than that?

Yes, the percentage usage will be lower, as it would if say you had an E2200 doing a task, it's percentage usage would be higher than an E8600 doing the same task.

As for how it's calculated, I've no idea.

I think it will be the same amount of usage but for less time, die to the mature of CPUs.

In some cases I would have thought this might be the case, but what about say for H.264 decoding whilst watching a movie? Wouldn't it only decode the move as fast as you watch it?

as far as i know it will decode it up to 10 seconds faster rthan the point you are watching, maybe more, same with CD's when they are playing, its noticeable sometimes when you eject the cd/dvd and it keeps playing for a few seconds longer

as for the original question i belive the higher the clock the lower the % usage for a given task

Yes, I noticed this when I had my CPU in stock and overclocked and I used the Winamp visualisation and and on Stock the % was slightly higher.

I think that would only be the case where the CPU is the bottleneck, ie running at 100%.
