LanOC Reviews reviewed the XFX RX580 Fatboy
A quote from the article:
Unlike Nvidia, AMD has actually had a few more recent launches, they all fell right in the middle of the coin mining craze though that played havoc on GPU prices and availability. The RX580 launched last April and then Vega came in August to fill some of the gap in the high end. The RX580 was a refresh of the popular sweet spot card, the RX480 that launched back in 2016. They were both on the Polaris architecture and here we are again with a new Polaris based card in hand. AMD is officially introducing the RX590 today, just two weeks short of two and a half months after the original launch. AMD surprisingly decided to stick with the 500 series naming and just slip in a card hoping to fill in the gap between the RX580 and the GTX 1070.XFX RX580 Fatboy Review
