My experiences with Rhyzen AMD (1700) CPU until now, are extremely
positive: it is very fast and reliable (used  in server to perform quantum
mechanics calculations). It is turned on 24/7, running 12.0-Release, since
January without problems or reminds. I think it is important to say: I
installed a water cooler system  (Corsair H45). In another machine (AMD FX
8325) cooled with a standard silver paste, CPU temperature rised until 80
oC during FreeBSD (userland and kernel compilation). After I moved to a
water cooler system , temperature is alway under 25 oC (during hard
processing work).

My 2 cents

Best regards

Edu
