Thx, been debating this or a 1920x or a 3600 for a htpc that will background hash. So Ryzen lineup is heavily bandwidth dependent? I'm aware that ryzen performance curve peaks at ~3600 ram spd so is that we are seeing with randomx as well?
my 1920x got around 7kh/s. overall the build was $500-700. Amazon has a deal going for $200 for the 1920x. I probably went overboard with the amount of ram. I thought it needed 2 gb per thread... no, its 2gb per numa node. and 1920x is just 1 node. So you could get away with 8gb to 16 gb prolly.
Some help on setup my rig is under preforming big time. i have a threadripper
I have found out that my first gen ryzens and
threadripper gets a few hundred more hashes using only physical cores instead of trying to utilize all of the cache so for example:
1920x
-t 12, --cpu-affinity 0x555555,
Going from 2666 to 3200 ram gave better performance with 16 threads.
R5 1600
-t 6, --cpu-affinity 0x555
this for xmrig. you can also try set higher cpu priority . --cpu-priority set process priority (0 idle, 2 normal to 5 highest)
Latest version should also give 2-3% better hashrate.
