Opteron announcement

[Bill Broadley]

Apparently the link to http://www.amd.com/opteronservers just went
live.  Tons of cool docs/benchmarks.

amd-244  26.7
amd-242  25.1
amd-240  22.7
Xeon-2.8 14.7

SPECfp_peak 2000 (single cpu)
================
it2-1.0   1431
amd-144   1219

SPECfp_rate20000 4P
===================
it2-1.0  49.3
amd-844  49.2
amd-842  45.0
amd-840  40.7
Xeon-2.0 20.2

Oh and one more interesting link:
Software Optimization Guide for AMD athlon 64 and AMD Opteron Processors
http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_739_7203,00.html

Amusingly all the submissions that I looked at the full reports for
use the Intel compiler.  So the Opterons extra registers are ignored.

Time will tell if 3rd party compilers that fully utilize the additional
registers can win benchmarks against Intel's compiler.

Based on the preliminary pricing I have the Opterons look to make for
very nice beowulf nodes.
