The AMD Ryzen 3000 series CPUs have been out on the market for a while, but for both the Ryzen 9 3900X and the newer Ryzen 9 3950X, seeing them in stock is rare. The AMD Ryzen 9 3950X went out of stock almost everywhere when it launched on the 25th of November on retail shelves. None of the major US retail outlets currently have the Ryzen 9 3950X in stock while limited quantities of the Ryzen 9 3900X can be found in some retail outlets.

Both the AMD Ryzen 9 3900X processor and the AMD Ryzen 9 3950X processors are currently out of stock at Newegg.com, and these processors are only available at a much higher price by third-party sellers. The Ryzen 9 3900X is almost double the initial rate on Newegg from a 3rd party seller and is currently being sold for $999.99 US.
