The problem with PCs is that the manufacturers concentrated on fast  
CPUs because that's what people were looking at. Desktop PCs have  
garbage disk systems, crappy power supplies and 32-bit slow PCI busses.

PC "servers" usually have 64-but busses, perhaps SCSI disk systems  
and maybe redundant lousy power supplies. Better, but still not the  
commercial device that an AS/400 is, as you pointed out. There is a  
reason the AS/400 costs more then several PC "servers".

The only way to really rate a system is with a battery of benchmarks  
that reflect how the machine will actually be used. Describing a  
system with a single number (CPU speed) is marketing, not engineering.
