Mainframe vs Microprocessor.
IBM's CMOS product line is based upon an S/390 microprocessor.
One processor per chip, with six such processors on a single CPU card
in the G1 family of CMOS machines. Perhaps more in later machines.
With the G1, and essentially all which followed it, there was
essentially no difference between a mainframe and a microprocessor,
as the mainframes simply used Generation X micros as the CPU.
The G1 was a six-way multi-processor which only burned about 1200
watts of power.
Six S/390 processors on the single processor card, with an additional
S/390 processor which performed the functions of the channel processor.
