FWIW, here are the SPEC scores for the HP workstation zx6000 and SGI Altix 3000 systems using McKinley. Since the HP machine is a DP workstation, you would expect higher integer performance due to optimizations around latency, rather than bandwidth.
HP: 807/--- SPECint 1422/1422 SPECfp
SGI: 683/683 SPECint 1396/1410 SPECfp
SGI improved their scores by 58% in SPECint and 46% in SPECfp (exceptional scalability, considering only a 50% increase in clock frequency and double L3 cache).
If HP gets the same percentages, they will have 1275 SPECint and 2076 SPECfp, higher than any other SPEC scores to date.
