FYI: Current SPECfp landscape...

[Bob Drzyzgula]

Wes Bauske was kind enough to point out 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...

Thanks, Wes.
