FYI: Current SPECfp landscape...

[bob at frb.gov]

It was pointed out to me that I could do the Pentium 4
system a bit more cheaply. I'd missed the fact that Pentium
4 boards are available with 4 RIMM slots, so one can use
256MB RIMMs, which are available at about half the price
per MB over the 512MB modules.  Thus, it should be possible
to do a 1.5GHz Pentium 4 system for a core (CPU+MB+Memory)
cost of around $1300 or so. A 1.7GHz system would cost
around $100 more than that. Updated tables below. Also,
I added SPECfp2000/K$. Fascinating how the Pentium 4 comes
out second in each one of these tables...
