What's confusing about the attribution and text that I quoted?

HP g9 and g10 are both well past the dawn of the era of low idle 
consumption so there aren't huge differences to be found there. The base 
power consumption of that class of system is rather higher than a small 
desktop primarily because of redundancy and BMC (IPMI/remote 
management)--not the CPU. A different server chassis & motherboard 
choice will result in much lower base consumption, if the redundancy and 
remote management aren't needed. But even the HP DLs of the g9/g10 era 
can idle at around half the 85W you mentioned. (Whereas a comparable g6 
might have idled over 100W, and even older servers idled at 300 or 
400W.) The point is that it's not correct to assume that a "server" will 
have a high idle consumption, and if power efficiency is a goal it's 
achievable through reasonable selection of components. (Conversely, a 
"desktop" may have higher power consumption if it has a beefy GPU, and 
older desktops have much higher idle power just like older servers.)
