"You've Got Four Cores" "But It's i3?!"
Hey All,
I recently got a 21" iMac refurb. It's an i3, with two cores. Or so I thought. Yeah, System Profiler says two, but everything else says four. MenuMeters shows four distinct cores with different numbers. Single-core Photoshop functions now use 25% or my CPU instead of 50% like with my Core 2 Duo MacBook, and things that let you do as many operations at once as you have cores now let me do four at once. Other apps say they are using four cores.
So, I'm not complaining; it's plenty fast. However, there are times when only one core can be used ( cough*CS5LensBlur*cough). 3.2/4=0.8; 2.4/2=1.2. So, these things take longer than they did with my old machine.
Is there any way to change the number of cores it thinks it has so that these things can use a full half the processor?
Also, who's right? Apple vs. everyone else.
Thanks!
