I don't think there is much of a debate, Intel has acknowledged but not
rebuted the claims. The G5/2ghz has a max theoretical of over 20Gflps per
processor with a dual independent 1ghz front side bus to each processor.
It does 64-bit calculations and all the benchmarks that I have seen are
all 32-bit benchmarks.

The only real rebuttals are that I have seen are:  

A they didn't include the Intel MMX libraries for testing purposes.
However, they didn't use Altivec enabled instructions either. 

B They used GCC instead of Intel's compiler which incidently makes a great 
Free Unix (linux/freebsd etc.) comparison. 

C They used unix instead of Windows for testing. =) *shrugs*

IBM makes the PPC970 chip. It wouldn't surprise me to see some IBM spin 
off projects that use this chip with both Linux and AIX for the low-mid 
range server products or for their blade packages since they are fairly 
low power still and cool. not to mention they can be used in 8,16-way 
configurations and they should be fairly compatible with the Power4 series 
software. 

As far as M$ goes, running Windows only through emulation is biggest knock
on the whole thing. If what Mike said is true and RealPC delivers. I don't
think emulation will be that slow. A LOT of speed is lost because
VirtualPC uses a trident/s3 as its emulated video card. Using the native
video instructions would increase the emulation speed literally by orders
of magnitude especially for gaming. 

I guess I'm not sure what there is to debate from a performance aspect 
unless you want to run Windows.
