BAD HARDWARE WEEK

3 Ghz, 12MB L2, SSE 4.1 , FSB 1333 Mhz. TDP 130W
Faster, 3.2 GHz Yorkfield will consume even 150W.
The benchmarks are here.

To be competitive against AMD's Altair, Yorkfield should run 3,5 -3,7 Ghz. But, it literally melts in every sense at 3,2 GHz and 150W TDP. Luckily, AMD's Altair will not reach 2,9 Ghz soon so, Intel could run still a bit.
Adjusted clock from the table above gives Yorkfield's corrected max clock ever : 3,2 Ghz
3Ghz Yorkfield launch is on November 12th.
