It seems that pretty much everything that goes into making a GPU is scarce these days: from components to silicon to wafers and even the memory that goes on board. Couple that with an overloaded TSMC and mining industry that's waking up from its year-long slumber and you have a recipe for disaster as far as gaming goes. Based on these reports, current GPU scarcity could extend well into the second quarter of 2021.

2020 has not been a good year for gamers, even though it has been a great year for gaming technology. It has been almost impossible to get high-end graphics cards at anywhere near their actual MSRP initially due to mining demand and then due to supply chain constraints. It seems that gamers still can't catch a break because a report from Cowcotland (via Videocardz) shows that both AMD and NVIDIA have been hit by GDDR6 supply constraints as well:
