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?

My R720 with 12 SAS drives idled at around 225W.

I’ve cut down the number of spinning rust to 6, and added 4 SSDs, now it idles around 120W.

I also enabled power capping in the BIOS at 250W. 2x Xeon v2, forgot which model, and 128GiB RAM.

I need to do that as well. My sas drives idle at 7.7 watts and under load run at 11 watts a pop.
