Be prepared for me Ryzens to be unobtanium. Intel essentially purchased a year of TSMC 3nm production capacity. Intel knows AMD is dependent on TSMC thus they made sure to cripple AMDs ability to manufacture at scale at that level. Intel has fuck you money put aside for AMD and is using it.

AMD was their largest customer for 7nm once Apple moved to 5nm. AMD booked their initial 5nm order a couple of years ago.
Intel has to pay through the nose to even get any sort of capacity as it is... let alone booking up the entire supply of 3nm which is unlikely since Apple will get first dibs.
Plus, Intel is not a long term customer and future contracts are an unknown and Intel is attempting to directly compete against TSMC.
On top of that, Zen4 is on 5nm and Zen5 could be either 5nm or 3nm and coming in 2024. By 2024, TSMC's 3nm will have been in mass production for about 1.5years and an Enhanced version of the node is planned. So the people that bought the initial 3nm supply would likely be moving to N3E or getting ready for 2nm in 2025 since that should be a big improvement with both Intel and TSMC moving to GAAFET, gate all-around transistors.
