You could probably just power limit a 9070 XT and get basically the same kind of efficiency though right? You wouldn't even have to go through the (potentially) long process of tweaking and testing like you would with an explicit undervolt / overclock etc so it's not exactly a tedious or difficult thing to do
You absolutely could. Adrenalin on Windows has a fairly easy way to get close enough to 220W TBP as an upper limit (negative offest is at most 30%, may depend slightly on partner model voltage properties). Following up on the sysfs interface for Linux.
Depending on the software you could drop the power target of the card basically to the non XTs level. I know on Nvidia MSI Afterburner lets you set it to whatever the hell you want.
What I've found if you want better efficiency is to clock limit the card. Find a voltage that gets you to about the power limit you want, then just make any further steps up be the same frequency and it shouldn't bother with those voltages. In Afterburner it's ctrl F.
My 4090 I have clock limited to 0.875v (lowest it will go) and it only consumes about 220-250 watts under normal loads, and under really heavy loads it's about 300 (350 is the most I've seen). It's been a while since I've tried that stuff on AMD cards, but based on my 5700XT in Mac OS I think it still works the same.
Good to see my 3080 still being able to hit 60+ FPS in all games at 1440. I probably won't upgrade until the generation after the next one.
It's too bad they don't have a 1080 Ti in their benchmark list, I am curious to see how it performs. I bet it does OK in non-RT scenarios; relatively playable considering that the card was released 8 years ago.
A 1080ti is a 2070 super which is a 3060 ti, which is a 4060 ti
