Show me the numbers for how AMD polaris has the best price performance.
I bought a Sapphire RX570 4G gaming for 130 brand new in january. It's got Samsung memory, can hold 2100MHz mem speed and gets 31-31.5MH/s mining ETASH
Mining CN Heavy: 915H/s
CN turtle: 8500H/s
CN Waltz: 1300-1320H/s
Any GTX1660Ti is twice more expensive where I live.
I'm not trying other algorithms, because I mostly want to mine privacy based coins.
I've got 14 RX570's sitting around. Turned them off several months ago, and haven't put them back to work. At $0.16 per kWh, whatever I mine currently makes no money so I just haven't bothered. At this stage, if I could be @rsed, I'd sell them off for $50 each. They paid for themselves several times over.
Still mining with my little 4 RX574 rig, I can pay the electricity bill (same 0.16$ per KW/h) and when price will rise again the coin should value much more than the cost of electricity.
