Sapphire Nitro+ 5700 XT and Red Devil 580 GPUs are the best ones I had experience with since last 4 years of mining. They both are very silent and mined for 2 years non stop. I stopped using them since ethereum merge. They only were used with phoenix miner

The Radeon 5700 XT has been on sale since September 2019, and for the first 4 months or a little more, the hashrate was minimal, because the miners did not optimize their software. Then there were many models with poor cooling, which caused overheating of video cards. You probably bought the most expensive models with the best cooling.

Agree that the hashrate was less than what others have posted. Also, I wanted less noise and was fine with lower hashrate. Same for my 580s from RedDevil. A bit expensive because I bought at the peak of 2018 but very quiet and worked non stop for over 3 years.

I don't understand when you bought RX5700XT video cards. The first hash rate was less than 10 megahash, so these video cards cost a lot and were not in demand among miners. Optimized miners appeared much later, then BIOS firmware appeared.

I had bought in Q4 2020 from Amazon. They were giving around 52Mhs on Ethereum.
