That's in order of dolphin performance. Notice the entire top half is Intel only. Wolfdale still outperforms anything AMD has despite being 3 years old.
clock to clock core to core conroe actually still outperform even thuban core (i'm almost sure even allendale wins against deneb on ipc/core alone).
also yorkfield is basically quad wolfdale, and is the "tock" of conroe/kentsfield, how could it be slower?

AMD is that far behind, and I have AMD main system btw.

Lower clock rates due to power consumption/heat. Dolphin doesn't care about it being quad core, it will favor a woldale slightly due to the higher clock rates (2.66GHz would be considered high end for yorkfield and 3.33GHz would be high end for wolfdale).

Probably about equal, keep in mind I'm talking about performance (which factors in both IPC and clock rate), not IPC.
Quote:err.. okay, I'm talking with overclock in mind since on modern processor, clockrate at >3 is a given.
Ok even moreso then. A yorkfield can get up to 3.8-4.0 GHz overclocked and a wolfdale can get to 4.5GHz pretty easily. Also the AVERAGE clock speed of yorkfield models is a bit lower than wolfdale.
Of course we need to compare it on clock per clock basis (which is my point from the start, we're comparing cpu architecture here, not SKU), I just mentioned overclock since you seems to bent on comparing it on stock clock (which if you do that, even some stock deneb and thuban could be more than a match for lower clocked yorkfield or even sb).
Probably a stupid question but what does SKU stand for? I can't seem to find any acronyms for that related to computer hardware.
SKU is part number, usually.
Very well. Reordered for performance per clock rather than performance (this assumes an application with two or less main threads like dolphin). Desktop microarchitectures only.

That's where bulldozer ranks in performance per clock. But this doesn't reflect performance since it doesn't factor in clock rates like my first list did. Bulldozer has similar performance per clock per core to an athlon X2. However when you factor in it's very high clock rate it ranks inbetween a phenom and phenom II in single threaded performance.

That's pathetic. AMD can't beat its own CPUs?
