I see a lot of discussion on what exactly the SKUs are going to be, and want to clear up some of the confusion with a very nice method.
If you visit AMD's support page for a SKU that does not exist, such as 2990XYZ, by adding it to the end of the URL: https://www.amd.com/en/support/cpu/amd-ryzen-processors/amd-ryzen-threadripper-processors/amd-ryzen-threadripper-2990xyz it'll return a "Page not found".
The correct, legitimate SKU will return and empty page with the SKU's name as the title: https://www.amd.com/en/support/cpu/amd-ryzen-processors/amd-ryzen-threadripper-processors/amd-ryzen-threadripper-2990wx.
By doing this we can confirm four SKUs:
Credit to /u/reyoctavio for his further analysis on my parent comment here.
EDIT: Seems like they fixed that, hopefully someone archived the pages. Thankfully a lot of folks saw it's true already.
