Imagine buying a RX5500XT at 750$+ just because of the love about power efficiency while I can get my hands on gtx1660 @350-400$ here in my country, isn't that a big difference and moreover the Hashrate are the same, I can grab a 27mh out of my 1660 @ 70watt and Yes 5500XT can do 27mh at 53watt, so tempting but price won't let me 😭😭😭😭 is there any insanely power efficiency GPU like 5500XT out there?
I don't believe the RX5500XT draws 53watt from the wall. Real consumption will be 10-20 watts higher. I have an RX5600 6GB Sapphire with Samsung memory. The real consumption is 90-95 watts from the wall with a hash of 39 megahash.
If you build 1 farm on 1660 graphics cards for $ 350, you definitely won't lose. You can recoup your investment in 1 year or less, but this is not certain.
