The Intel processors reduce power during wait.
Not exactly true. It depends on many factors. Note: laptop is not good
comparison to server.
I know; I have one. When it's busy
the chassis gets hot and the fan turns on.
See above. It can be desktop PC as well. Look at CPU-ID program and
watch GHz speed. It's changing constantly. For servers it is usually
disabled.
Long ago I learned here that IBM processors
never reduce power. Is that still true?
No, it's not. Look at POWER presentations. Or simply break cooler in
your CPC.
