260 million cores is 150-300 GH/s RandomX total, depending on how many of them are Zen2

hyc tevador hmm, this is the first scatter graph where CN/R ASICs are clearly visible: i.imgur.com/HJTTILf.png

They appeared around block 1948000

October 19th, 2019

More than a month before RandomX fork

or ~7 months since CN/R fork

But since there were only ~30 MH/s of them, overall hashrate didn't jump and they just replaced some GPU miners

They earned $360-400k in total (if selling mined XMR immediately)

Has anyone gone public with CN/R asics?

or is it all based on nonce-interpretation?

i think nonce interpretation Inge- . was that just done by visual inspection sech1 ?

and sech1, can you resolve between asics vs. FPGAs?

damn, nanopool saw a jump from 139 to 252 Mh/s recently

and it looks like the hashrate didn't come from another pool, nor did it go back to another pool

I already knew what to look for base on Sumo nonce analysis: reddit.com/r/Monero/comments/eqecqn…ghtr_is_mined_by_asics_or_fpgas_now

It was just not visible on my own graphs, but that one with thicker points makes it clear

It's ASICs. It doesn't make sense for FPGAs to start mining 7 months after algo change, they could've done it in a few weeks.

30MH is kind of a small number compared to earlier ASIC inflow

Maybe it was just a small batch or something that used cheap 32nm or 65nm node (i.e. less efficient)

plus CN/R was more asic resistant compared to previous variants

still a pretty cool find

And AFAIK nobody has gone public with these ASICs - so the only trace is from nonces?

The trace comes from nonces and the fact that Sumo is not profitable for GPUs (at all)

Isthmus, i forget... have u tried statistical magical on nonce distribution to detect asics? if so, can u confirm sech1 's finding?

sorry, statistical magic

do zen, zen2 and zen 3 all use the same socket for board reuse?

kinghat: yes, with zen 3 being 2nd generation

👌

though not all older boards get sufficient BIOS updates to handle the newer processors

some A320 boards can run Zen2, and most all B450 boards, X470 boards ..

problem with A320 was not enough bios space for gui + support for old and new CPU's iirc

so some had specific non-gui BIOS to support 3xxx cpu's
