I have it on good authority that with the other chipset (we have a Blackford here), we should see higher numbers. Not exceeding the Opteron 275 though.
We have both a greencreek based (the one with the snoop filter.. I guess they're calling it the 5000x now) and a blackford based system and I'm not seeing any difference beyond a percent or two of performance either in stream or in real applications. Maybe we just haven't hit the magic app that greencreek helps yet.
What I can say is that Woodcrest is interesting. It just may be overhyped by a "compliant" media.
I'd say it's a bit overhyped, but it is giving us some good real application numbers compared to the opterons. On NAMD, Amber, and VASP so far, we've seen 2.66 GHz Woodcrest between 10-20% faster than our 2.4 GHz dual-core Opterons while using all 4 processors in a box. It's not the 50% media hype numbers, but it's definitely an improvement on the Intel side.
