Well the dust has settled and Yorkfield benchmarks are coming out all over the place. So let's recap. The average OC on air seems to be ~4.5Ghz with these early ES chips.
But there's one very obvious problem. These OCs are from an unlocked multiplier.
Intel intentionally released their highest end first to bolster an image of what their future chips could be. But before we get swept away with all the good press, we have to remember something; what board could possibly get a locked Yorkfield to 4.0Ghz+? The Q9550 runs at 2.83Ghz with a 333Mhz FSB (and also sells at a steep $510 on release). That makes a multiplier of 8.5. Now to get to 4Ghz, you would need an FSB speed of 470Mhz.
Seems easy enough? Well it's not. Dual cores are much different than quad cores when it comes to max FSB. The max FSB of a dual core is MUCH higher than that of a quad. Quad cores use much more bandwidth because of the extra cores. This leads to a much greater load on the NB.
So if you're waiting for Penryn, I would suggest waiting for the board as well. The P35 or any other board out today probably won't get the OC you were hoping for.
