  1. ^ a b E or "Extreme" branding is a guarantee that PCIe 5.0 is supported on both the motherboard's graphics slot and NVMe slots. E models provide access to all 24 PCIe 5.0 lanes from the processor. Non-E models only support 8 PCIe 5.0 lanes on NVMe slots while the rest of the lanes on graphics slots are dropped to PCIe 4.0.
  2. ^ PCIe lanes provided by the chipset. The CPU provides other PCIe 5.0 lanes.
  3. ^ Motherboards marketed as X670 and X670E feature two Promontory 21 chipsets, each having a TDP of ~7W, giving a total TDP of ~14W.
