News Samsung Hikes Chip Production Prices: GPUs, SoCs Set to Get More Expensive

The price hikes should not immediately affect GPU and SOC prices. I believe prices are fixed for an agree period of time. So it will surely affect later batches, though not sure when.
 
Not just supply and demand but inflation (clearly growing in the US) is a factor I'm sure.

Especially if contracts are written in US dollars. I'm not sure how common that is in Korea but it is common in other international trade contexts.
