The only benchmarks for rx1600 are at 1 Ghz, and SPECfp peak is only
1382.  If the $3,000 system is only 1 Ghz, that's not so great price
performance, compared to say a 2.2 Ghz Opteron with a SPECfp peak of
1691.

Perhaps HP does have a faster CPU for the rx1600 and didn't submit a
SPEC score for it? But then what's the price?
