What's the command to benchmark leela again?
Open cmd with or without admin privileges, then cd "Lc0 path"
In my case:
lc0 benchmark -w C:\Users\YOUR USERNAME HEREl\Documents\Chess Engines\Lc0\384x30-swa-3180000.pb

I have a question.
I can buy a dual 2080 OC with 8gb GDDR6 each
for a similar price as
A single 2080 ti OC with 11GB GDDR6
Which would give the stronger Leela performance and by how much?
Obviously the 2 x RTX 2080. I have 2 x RTX 2060 OC and I get the same chess power with them than an RTX 2080 Ti OC.
You can suppose from 2 x RTX 2080 about 150 % chess power (but not in Elo) comparing with 1 x RTX 2080 Ti.

Another thing to notice in this table is that fp16 numbers tend to be >> 2x fp32 numbers.
This makes me a bit suspicious.
The ratio is about 2.6 and the numbers are right.

I was told some time ago that 2x RTX 2080 Super OC ~ 150% comparing it with 1x RTX 2080 Ti.
Maybe it's above 150% ?

Maybe you patented your statement?
What a surprise I also think so.
