If you actually need the CPU power, the Threadripper is likely the more ecological choice. Sure. it's higher power, it's harder to cool, but if you get twice the cores and actually use them...

No. I used to look at the Xeon CPU's, and I could never really make the math work. The Intel math was basically that you get twice the CPU for five times the price. So for my personal workstations, I ended up using Intel consumer CPU's.
The AMD Threadripper pricing is much closer to "twice the price for twice the CPU". Yes, you end up paying more for the accoutrements (MB and cooling), but that's pretty much in line too. So yes, it ends up being more expensive, but if CPU power is what you want and need, the expense is pretty much in line with what you get.
AMD has their actual server CPU line too, and you do pay more for that privilege, but at least AMD doesn't try to screw you over and limit their non-server parts. So you do get ECC for Threadripper (and plain Ryzen) too, even if it's not necessarily "officially verified".
I'm personally very happy with AMD these days. I used to absolutely despise their horrible bulldozer cores, but I think they've had a home run with their Ryzen series and their chiplet approach. Not just because they fixed their cores, but because their chiplets made it so much easier to do the scaling they do and offer close to that "twice the cores for twice the price" model.
Intel with their HEDT and Xeon chips that required different boutique silicon (and thus the excessive pricing) is dead to me unless they seriously fix their sh*t. I've been complaining about their ECC policies here on this forum for about two decades by now. Good effing riddance - because once Intel stopped offering the best bang, there was absolutely no advantage to staying with them.
