I ordered a 5900X in November 2020 at a large wholesaler who keeps offering the CPUs at SRP since the official launch, at the same time their backorder at AMD kept increasing to well over 5000 units. Since my order in November the well known German retailer "Mindfactory" kept selling the 5900X starting at about 100 EUR (+VAT) above SRP. Sometimes they would raise the price shortly before selling out, but once a new shipment arrived their price went down to said +100 EUR again. Meanwhile all other retailer asked for considerably higher prices.
Sometimes Mindfactory would have CPUs for a whole week in stock with prices changing slightly up and down +-20 EUR. Then they were sold out again just to get new units two weeks later.
Two weeks ago I gave up on my November order, especially since the wholesaler's salesperson told me that they don't expect shipment before the end of 2021. I then bought the 5900X at +100 EUR (+VAT) from Mindfactory, but only build it in two weeks later. Turned out that this time the CPU did not sell out within a week and thus the price dropped another 34 EUR (+VAT). Bad luck for me, but I really had to get the CPU now to work with it and finally try if the MSI X570 Creation mainboard I also bought 5 months ago is even working.
