Doesn't really matter. CPU mining will never be as profitable. Whatever hashrate new Ryzen processors are getting they will never hit ROI so there is no point in buying them with mining in mind, and if you want to mine from time to time there is no profit (just a few bucks)
are you serious? do some research, it is true that cpu has lower roi but they will hit it... When zec was out the first 2 weeks were great for cpu miners + ryzen should have greater performance and consumption, I need some cpu to my rig, why not buy on which can earn me money?
If you are right why are everyone using GPU over CPU now ? Difficulty is constantly increasing and with low CPU hashrate you will eventually be in a loss. Ryzen cannot earn you money. For that 350$ (1700) you can get almost RX 470 and for a few more bucks you can get another one. CPU mining is just a nonsense. I asked you something last time. Chose cpu and algo and please let us all know what is ROI time and then compare invested money with some GPU in same price range and then tell me CPU mining is any profitable.
GPU/CPU depends on the algo selected for the coin. Some GPUs cannot mine certain algos (Nvidia cards cannot mine Xevan algo) so for a person with an Nvidia coin who wants to mine xevan, a bank of CPUs may be better for them, even though they wont be getting a lot of coins.
RX470 prices are up to $900 on some sites. on new egg its $470, good luck finding them in stock. And say you buy one for $350 like you say, where can you get a second for "a few more bucks"? that's a hell of a deal
what the hell are you talking about, nvidia mines xevan just fine. Ive been mining xlr with my 2 1070s and 1 1080ti at over 12mh/s
back on topic my ryzen 1700 seems to be be getting low hashrate compared to some people here. I have it oced at 3.5 and using xmrig im getting around 550h/s. cpu load sits just above 50% though as its only using 8 threads.
