Further info.

best* SPECint 589 8800
best* SPECfp 884 840

obviously this is per processor, and probably reflects Sun's SPECfp
"hacks"**

*I had to compare Apple's figures for the G5 from
"G5_Processor_WP_062303.pdf" from
http://www.apple.com/powermac/performance/
vs. official figures for Sun from www.spec.org

**Sun's Forte compiler defeats the cache-busting attempts of one of
the SPECfp benchmarks which inflates their SPECfp scores
disproportionately compared to how often one could expect to enjoy
that kind of analysis and speedup with real code
