At 1GHz, Alpha EV7 was about 10% faster than Alpha EV6 on SPEC INT2000. The EV7 is just the EV6 core with an all-new "platform."

If Tukwila debuts at 2.2GHz, then I'll estimate it will score around 25 on INT2006 (base), which is close to the scores for the 3.33GHz Core 2.

Keep in mind that libquantum is a broken benchmark. Core 2 Quad scores are inflated by 25% due to it.

I'll put my chips on Tukwila being released at 2.0GHz, and achieving 2.4GHz in it's lifetime. How do you feel Tukwila will fare against Nehalem in the quad socket market on workloads like TPC-C/H, SAP-SD, SpecJBB, etc?
