I operated Shredder at the IPCCC in Paderborn on a Quad Mac with 2.5 GHz. We
calculated that it is as fast as an Quad Opteron at 2.5 GHz (+/- 10%). A single
G5 is slower than a single Opteron (for chess!) but the speedup for 4 CPUs seems
to be better. The overall result is about equal.

Btw: Seeing it that way a quad Mac is one of the cheapest available systems with
that much "chess calculating power"!
