I want to see all i7's O/C to 5.0 ghz on air, which Francois just claimed to have achieved. So by the same standards, you should expect all i7's to equal that mark.
CPU speeds are on a normal distribution.
http://en.wikipedia.org/wiki/Normal_distribution There will some fast ones and there will be some slow ones, and then there will be a lot in the middle. If you go far enough down the curve, you can find some really slow parts.
Why is that? Well its intels Who saying AMD cheated.
I read every thread that I could find over at XS on this, and I never saw anyone from Intel saying anyone from AMD cheated.. if anyone finds a post like this, I would like to see a link. Francios said that it's possible to cheat - not that that this occurred.
While he could (should) have chosen his wording a bit better, he has a point about not trusting any manufacturer overclocking. It's one thing for some guy to tweak his system, but when manufacturers do it, it's best to take it with some level of distrust. And this is
any manufacturer - with CPU's and GPU's or any other synchronous complex CMOS integrated circuit, there's a lot of behind-the-scenes tricks that can be done. Some are common-sense (disable overcurrent checks, disable thermal limits), some are semi-legit (pick fast parts, use LN), and some are very dubious (hypothetically, disable the L2 cache because you have a bunch of speed paths reading the L2, and then choose benchmarks that don't hit on the L2 at all, turn-on single-issue mode and don't run any benchmarks... the list is extensive including really funky ones like re-write the microcode or using arch-break handlers... I could go on).
Francois could have chosen his wording better, but I agree with his sentiment - which is not to put a lot of faith in any manufacturer demo'd overclocks as indicative of anything except that manufacturers are very good at tweaking their parts. This probably applies to more than just CPU's and GPU's too... cars, planes, anything where manufacturers are trying to show speed.
