Yesterday, Cowocotland, a technology website, has published information that AMD's reference design cards like the latest Radeon RX 6900 XT, RX 6800 XT, and RX 6800 GPUs are getting discontinued. That means that AMD will stop the production of the reference designs and rely completely on the supply of GPUs coming from add-in board partners to satisfy the market needs. This does not mean that the availability of these GPUs is not going to exist. Rather, there will not be AMD reference designs available for purchase from the company. Only cards that are custom made by AIBs, that AMD provides GPU+VRAM for, will offer customers cards with these GPUs.
VideoCardz claims that they have been able to confirm some pieces of the information, so it is a done deal. From now on, it seems that only graphics cards with Radeon RX 6900 XT, RX 6800 XT, and RX 6800 GPUs inside them will be the ones offered by AIBs. The reference design cards will only be produced until early 2021, giving it a month or two for consumers to purchase cards from AMD. After that period the market will rely completely on AMD's partners.
Update 4:30 pm UTC: Scott Herkelman, CVP & GM of AMD Radeon
Tweeted that they have "extended the reference design builds indefinitely due to popular demand." Meaning that the reference cards will remain in production. Mr. Herkelman also thanked for feedback, where community was loud and clear that they want to see reference boards for a while longer.
