I just want to counter this one point. POWER9 is absolutely not power
hungry. I've seen the 8-core chips idle at under 10W, with active loads
maybe in the 40-60W range. We're dogfooding one machine in a typical
office setting, and it dissipates nearly no heat -- it's using less
power than the older Xeon it replaced.
