Old server hardware - R710 vs R730 power efficiency? (alien.top)

Wondering if anyone has a feel for the power efficiency of older server hardware. I'm reading posts from people who say they have R710 with lots of hard drive and it IDLES at 160W with 8 hard drives. So...if you take the hard drives out of the equation, it's probably still like 120W. Is that just how inefficient old computers are? Kinda like incandescent bulbs are less efficient than LED bulbs? How efficient is the R730 compared to the R710?

My 6 year old desktop computer is 60W idle with a GPU, and 30W idle without the GPU. Seems like a huge difference. It's like $70 more per year to run a R710 than my old desktop with a GPU. Is that correct?

I forgot there is also a gtx 1650 in there as well.

But honestly. I’m fairly sure the majority of the power draw is the 4 CPU’s.

96 cores and 192 threads on older architectures was a bit of a power suck. If I had it all to do over again I would for sure have gotten an epyc chip instead.
