First off FUGGER never said it would go to 4G on air, the guy who gave it to the guy whos giving it to him is daid by the middle guy in the chain to have said it

So basically its been said by someone who nobody knows except FCG, and who probably aint very trustworthy seeing as they leaked a scret chip out to the public

So, at least personally, I consider that a complete fairy tale. I haven't seen Yonah go much over 3G on 65nm, and Presler only goes 4G, but its pipeline in 31 stages instead of 14. So i'll be amazed if this chip gets more than 3.2G, epsecially considering that its an old ES chip, and Conroe only launches at 2.66.
Also, for those people wanting independant confirmation of Intel scores, FUGGER posted several Merom benchies, so those are free of Intel interference, and still show about 20% IPC increase over Yonah in many apps.
EDIT: also, the quad core server chips have DIB at 1333, so thats 2666 effective bandwidth to the chip. Hopefully thats enough

Don't really know if it is though seeing as they also have 4 channels of FB-DIMMS...
