GPUs are a marginal factor in this. The main factors are several impacts from Covid-19, US trade restrictions on SMIC chip exports from China (a big supplier of low and mid-range chips which this is actually all about), and the Taiwan drought. The Covid-19 impact itself is multi-pronged. Many chip plants closed or reduced output due to the lockdowns, but also the silicon used in chip production is the same material used to manufacture vials so vaccine production also impacts high quality silicon availability. Finally early in the epidemic a lot of manufacturers that consume chips, such as car makers, cut production. This lead to some chip foundries being closed as they were non-viable and it's taking a long time for those foundries to get re-commissioned or other foundries to expand to make up the gap in capacity.
