There’s a global chip shortage due to

1) covid-19. Factory closures, employee, and supply chain issues. 2) 30-40% growth in gaming due to covid-19 3) trump tariffs (for the USA). Gpu exemption expired in January.

Crypto is affecting prices but they aren’t causing the supply issues. I don’t think amd has produced many 6800/6900s. Ryzen 5800/5900 cpus are rarely in stock.
