Which CPU is the x86? The modern x86 CPUs (such as Core2) will be significantly faster than the PowerPC, even at comparable clock rates. Have you just compared even C code tests?

I think that goes a long way towards explaining it... a simple C loop that I tried runs for 4.5s on the PC and 30s on the Mac. So probably this isn't GHC's fault. Thanks for the suggestion.
