I have a GTX 1660 with 6G ram. The load is about 3,5G with the 4 Allies running concurrently.
I have to see if 4GB are enough, then.

Re: what is the oldest hardware when engines at GM level?

In blitz Rexchess was already GM level about 1990 on my 25 Mhz 486. 2500 Elo GM? What about standard FIDE time control, when would you say that happened and what engine achieved the feat? Yes, we played in a WBCA blitz tournament and made an even or plus score against GMs, all in the 2500s FIDE or ...

Zen2 is a nice processor, unfortunately it has some weaknesses.
Biggest weak spot so far: price.
  • Black Friday 2018: Ryzen 7 1700 for 165.99€ at Amazon.
  • Balck Friday 2019: Ryzen 7 2700 for 149.99€ at Amazon.
  • Black Friday 2020: Ryzen 7 3700x for a similar price? If so, weakness removed.
