Phoronix reported this morning that an additional 17 PCI IDs for AMD RDNA 2 GPUs including Navi 21, Navi 22 & Navi 23 have been added to the Linux kernel graphics driver. The reason for the addition of these seventeen PCI IDs is unknown, but it is odd due to a large number of PCI IDs already in previous patches and might hint that AMD is readying either a refresh of its existing products for next year or these are simply custom designs for partners.

Does this lead to a possibility of more RDNA2 graphics cards being launched by AMD? It does lead to a large amount of speculation, but it is noted that companies do set aside a group of IDs that could be used for "engineering models," that are added for future models that have yet to be released, or even similar IDs for similar models. The other option could be customized versions that were made for AMD's large line of partners.
