The first batch of AMD Shanghai Opterons will run between 2.3GHz and 2.7GHz with a 75 Watt TDP. Next quarter though AMD has announced they will deliver a 55 Watt version. AMD will also be delivering a 45nm desktop version of Shanghai, which they have codenamed Dragon. Unfortunately, we don't yet have our hands on these new AMD CPUs, so unfortunately there are no Phoronix Test Suite results to share at this time.
For more information on the new AMD Opteron server/workstation processors, check out their press release.
