   Is it really *that* inefficient?  Sounds even more horrible than what   
   I'd expect.  Do you have some reference?

   Even if we consider "CPUs" their power consumption can go much further   
   than just that of the cores.  I remember reading about Threadripper   
   spending about half its power in the its interconnect.   
   Still, I suspect you need a lot of RAM before it starts consuming more   
   power than your CPUs (at least the kind of RAM you find in gaming   
   desktops consume significantly less than the CPU, last I checked), so it   
   likely depends on the workloads that are targeted.
