The CPU may be rated for different highend vcore and it ma have different prefetchers but again, "may have" is still just a guess. Certainly there seems to be some small differences based on the spec sheets but from a functional and overclocking perspective there seems to be no difference and telling people that they are "binned" differently is still not proven by anyone. It is all speculation.
However, if you get a chip that's 1.36v out of the box (as in the worst E8400 Intel produces from their own docs), and I get an 1.225v Xeon E3110 (worst I can get), I bet money I'll get to whatever speed we pick (you say 4ghz) with less volts! The odds are already in my favor, as I'm starting lower out of the gate at the same speed as you. Chances are fairly good I'd have the better chip to start with in this case (and many cases between these two chips). Why do you think they are NOT selling desktop versions to servers? Because they run hotter/more volts. Fairly simple deduction. Has been that way forever. Now if you want to talk batches between the same family OK. Agreed some might tend to be better. But I don't think so across families. Like between four specs of Xeon's maybe one is better on avg.
Is it speculation that I'll get a guaranteed voltage 1.225 or less? NO. IT's fact. The same can't be said of E8400. It's roll the dice, you could get 1.36 which would by most testing in the world mean you're going to be hotter out of the gate and call your chip crappy. Now how would you BIN a chip to find ONLY the ones BELOW 1.225v? I'd say you're picking the best ones (at least "better" ones) wouldn't you? I'm having a hard time understanding why you don't get this. I don't even get how you can say 1.22 vs. 1.36 is a "small" difference? Odd, that's a LOT of voltage in our little world here. I'm not saying batch has nothing to do with it. But logic tells us voltage out of the gate has a lot to do with your starting/ending temps. What kills your chip? Volts. Hmm...Guess I want lesser in most cases then right? I don't see too many people liking high voltage, they end up backing off for 24/7. Maybe I'm way off, but I like logic, and my odds. Spock kicked butt.
