max voltage limit 0.9v
tdp limit 90w from 125w
same performances?

I achieved something similar with my old 1070 four years ago. ~110 W (of 150) at 99% of stock performance.

In your opinion, how much can we go further down without compromising performance? what voltage?

I think anything lower than 870 mV will be unstable at stock clocks. Still, silicon lottery to consider.

how many watts do you want to read?
by cheating on power sensor I can get the numbers you want but it would be a fake.
however I still have to test if 0.875v is stable on timespy stress test...

1969: people are reading books.

stable but is limited by 90w, voltage varies between 0.8-0.82v, I can still improve, I have margin...
S.N.N.
the Wall!!!
it's not much... about 200 pts of timespy less without touching vram. it takes about 95w for a draw with a little more voltage. assuming that watts shown are real and I have my doubts.
I noticed that during timespy stress test, probably due to increase in temps of VRMs, around 3-4W of efficiency was lost.

I tried replacing thermal paste on 1660S and the situation improved by 1-2°.
now it passes the stresstest with stock bios, before it failed with 80-81°.
I also tried the carbon thermal pad which gives -1° more than paste but I have now removed it.
However, I believe the solution is permanent undervolt.

with 100w the performances are practically the same, but with 70° and without fan noise.
this 1660 super mini is not that great.
maybe it can be improved further, however in a long gaming session it should be even better, average clock +35mhz .
from the third lap efficiency begins to degrade
stabilized with some small adjustments... 1935mhz 0.825v and it never goes down, effective speed is 1950->1927mhz, temps +1°. next step 1995 but I don't think it will be possible without raising voltage.
