Ethereum trades at $377 today and has been trading in a range of $350 to $430 in the past month or so. VideoCardz reports this is driving demand for AMD's Radeon RX 500 and RX 5000 series video cards.
Despite being four years old, AMD's Polaris GPUs are still in production. The mining demand definitely explains why some of these chips haven't been retired yet. The Navi 10 based GPUs have comparable performance but are less cost-effective. Similarly, the NVIDIA Ampere-based GPUs aren't that attractive for mining, at least not at current prices.
