I have Ryzens in my rigs - built especially with monero in mind and my results are following (large pages enabled in Win 10):
Ryzen 5 1600X (3,8 Ghz at 1.23V) - stable 540 - 550 Hash/s - consumes ca 44W from wall
Ryzen 7 1700 (3,8 Ghz at 1.23V) - stable 630 Hash /s - consumes ca 44W from wall
I believe that I can get near 4 Ghz - but this setup is 24/7 rock solid and doesnt lead to unnecessary restarts of the system. Wattage was measured as a difference between idle system and CPU-only mining turned ON.
Ill build new rig with Ryzen 5 1600 this weekend - but I guess the results will be same as for 1600X - cause L3 cache and number of cores are identical.
Thanks for the info I am pretty interested in seeing what the Ryzen 5 1600 does if you don't mind sharing!
We have 5 of them and they do ~430 (max of about 460 on one, lowest about 420) on Monero at stock settings. The motherboards they are in don't seem to support much in the way of overclocking so we left them at stock settings. On a gaming oriented motherboard they should overclock up close to 4.0 ghz for a decent boost in hashrate with a little more power consumption.
