AMD’s RDNA 2 GPUs Including Navi 21, Navi 22, Navi 23 Receive 17 New PCI IDs – Could Be The Alleged 6nm Refresh

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.

The IDs add five Sienna Cichlid, five Navy Flounder, and seven Dimgrey Cavefish PCI IDs.

  • Sienna Cichlid (0x73A5, 0x73A8, 0x73A9, 0x73AC, 0x73AD)
  • Navy Flounder (0x73DA, 0x73DB, 0x73DC, 0x73DD, 0x73DE)
  • Dimgrey Cavefish (0x73E8, 0x73E9, 0x73EA, 0x73EB, 0x73EC, 0x73ED, 0x73EF)

Rogame also believes that these PCI IDs for special models which could be for PRO & special GPU variants.

Could there possibly be a refresh of RDNA2s, the Navi 22, 23, and 24 GPUs from AMD that could launch in conjunction with the new Navi 3X RDNA3 lines? Again, the answers are simply unknown at the moment. It was previously rumored that AMD is planning to only release three Navi 3X GPUs along with a refresh of AMD's current graphics card lines utilizing an optimized 6nm process node.

Right now, we do not have enough details to gather anything but rumors and speculation. The new AMD Navi 3X lines should start to appear within the next year, and if a refresh on RDNA 2 GPUs is to happen, it will be during 2022.
