It's about 40-45 Elo FWIW.

I don't think you'll get to 80 knps with a regular 22 core machine or
whatever they use. Remember that AZ hardware is about 16 x 1080 Ti's.
You'll lose that (70 - 40 = 30 Elo) advantage very, very quickly.
IMHO this makes it all the more clear how silly it is that so much
attention is given to TCEC with its completely arbitrary hardware choice.

Probably the same the Zen team did. Ignore a large part of the result
because people's actual computers - let alone mobile phones - can't run
a neural net at TPU speeds.
The question is if resizing the network makes the resulting program more
competitive, enough to overcome the speed difference. And, aha, in which
direction are you going to try to resize? Bigger or smaller?
