CPU Usage Question

post #1 of 6
Thread Starter 
I'm not sure how CPU usage works but let's say I am using 90% of my CPU at stock settings (i7 930 2.8 ghz). If I were to overclock that to around 3.6 GHz to 4.0 Ghz, what would my expected CPU usage be?

Not sure if it's linear...assuming it is, your usage at 90% and 2.8 Ghz would be 63%? at 4.0Ghz? I'm just throwing this out...not sure if this is how it works though.

Yes your CPU usage should go down as you increase the clock speed… Think of it as time slots, the higher your clock rate is the more time slots are available for data registers to perform their Boolean algebraic equitation’s…

It is hard to say exactly how much as Intel CPU's (CISC) uses predictive processing and hyper-threading, unlike a RISC (Reduced Instruction Set Computing) processor with a set amount of registers that always take the same amount of data in each clock cycle a CISC processor (Complex Instruction Set Computing) takes what is FIFO (First in, First out) so the exact amount would be hard to say, but the faster the speed the more times slots that are available and that is what will lower you overall CPU usage…

But if you're doing folding, you would use 100% of your CPU at all times no matter the clock speed.

Not doing folding but running multiple clients of the same game. When I run around 6 clients, my usage is about 40-50% but once I open past 8, usage jumps to 90%+. I was just curious if overclocking would lower the usage or at least allow me to run more clients with the same amount of usage.

The odd thing is that the game doesn't even have an affect on my video card.
