There is no "supply and demand" here, people misuses that terms without a degree in economics, often
the supply has constraints, also 5800x are the worse value and run incredibly hot except on custom loop in which case probably you go for a 5900x o 5950x anyway, also it seems some Gigabyte MB with 5800x crash PCs, just googled it as I was curious why no one is purchasing them, plenty of threads out there.
Yes, Intel not supporting PCI4 on 10xx was a big mistake, I am looking at AMD only for that as CPU is the thing we probably change the least, even more so for people mostly gaming...it seems a very interesting CPU however it will probably draw more power than a search light on a ship but indeed considering how bad AMD is with several things and motherboards offering it may appeal quite a few people, also Intel manufacture their own chip whilst AMD is sitting even behind Apple with TSMC queue due of investments.
Just guys avoid pay overpriced price, already these CPU are overpriced...I am not looking to purchase here anymore, I mean OC UK is selling £40 more than the couple of scalpers I checked on ebay as comparison for the 5950x, it says it all
