Hi,
Yes, the SPEC numbers aren't representative for typical gromacs
performance.
Technically I'm still on NDA for the benchmarks I ran on Barcelona so
I can't share the exact numbers with you, but on average the
performance will be pretty much the same _per_clock_ as Intel
Clovertown. AMD scales a little bit better, but Intel benefits from a
larger cache.
Still, it's very nice to see that AMD is at least back on the field
again. Let's hope for an aggressive frequency ramp-up and a price
war ;-)
Cheers,
Erik

Hi,
Barcelona is out now and SPEC CPU2006 (www.spec.org) has released
new numbers (I have taken them from the german c't magazin
www.heise.de):
Single core performance:
435.gromacs
Opteron 2350 74.4
Opteron 2222 51.1
Xeon X5365 143.3
Caveat that these numbers are for simulations without assembly
optimization - i.e. C nonbonded loops. The assembly ones are
considerably faster. Ref - GROMACS website.
