Prime 95... one core faster?

[eklipz330]

So I was running prime 95 v25.8 build 4 for a few hours, and i realized core 0 was going faster than core 1... it was at a higher test number, although just a few.

Should i be concerned about this? Anyone know why it does this?

it was an e8400 @ 3.6ghz [1.2v w/ vdroop] on win7 x64 if that helps at all

It's fairly normal unless it is MUCH faster. Remember that Windows processes will suck some CPU cycles as will any background tasks.

im an idiot, i should have figured that out myself, thanks man!

Core 0 is the actual core thread, while core 1 uses hyperthreading. Hyperthreading makes use of what the actual core isn't using, so the hyperthreaded core will not have as much power at its disposal.

Post that in a thread where the OP is using Hyperthreading.
