I believe this is absolutely true for the reality that is now.I think these companies have become spooked by their revenues falling a huge amount. So they want to increase prices and margins to compensate. What they seem to not think is the pandemic was a rare event for tech,ie, a situation where a lot of people and companies had to upgrade their PCs for work/entertainment and mining hit at the same time. Now they want even higher margins,and sell off their overproduction for miners at RRP.
AMD and Nvidia have had a wild ride during the last 24months and completely forgot about what the fundamentals were that propped up their revenue and profits.
Anyway they probably over leveraged on their wafer and fabrication cost as well due to TSMC being in so much demand by all tech companies. Nvidia reportedly invested $10-20bil into TSMC 5nm fab.
