  1. ^ More likely need a BIOS update if the motherboard was manufactured in a earlier date.
  2. ^ Support for Gen5 speeds on lanes directly from CPU to expansion and M.2 slots, and general-purpose lanes. (Also depends on CPU PCIe support. Some CPUs have as low as 10 lanes of PCIe 4.0 available.)
  3. ^ The "first" M.2 slot.
  4. ^ Some motherboards connect GPP lanes to a second M.2 slot.
  5. ^ PCIe lanes provided by the chipset. The CPU provides other PCIe 5.0 and/or 4.0 lanes.
  6. ^ a b c d The motherboard maker may configure the total of 6 USB 3.2 lanes provided by the chipset into "4× USB3.2 Gen 2x1 and 1× USB3.2 Gen 2x2" or "6× USB3.2 Gen 2x1 and 0× USB3.2 Gen 2x2" ports.
  7. ^ a b c d The motherboard maker may configure the total of 12 USB 3.2 lanes provided by the chipset into one of the following:
    "8× USB3.2 Gen 2x1 and 2× USB3.2 Gen 2x2",
    "10× USB3.2 Gen 2x1 and 1× USB3.2 Gen 2x2", or
    "12× USB3.2 Gen 2x1 and 0× USB3.2 Gen 2x2"
  8. ^ a b Provided by a third-party controller.
  9. ^ AMD did not mandate which Wi-Fi version should be paired with which chipset (unlike USB4 is mandatory with some chipsets). Motherboard makers may omit Wi-Fi on some models.
  10. ^ a b Two Promontory 21 chipsets are present, each having a TDP of ~7 W, giving a total TDP of ~14 W.
