AMD Radeon RX 6500 XT is limited to PCIe 4.0 x4 interface

The recently announced AMD Radeon RX 6500 XT only features a PCIe 4.0 x4 interface according to specifications and images of the card published on the ASRock site. This is equivalent to a PCIe 3.0 x8 link or a PCIe 2.0 x16 connection and is a step down from the Radeon 6600 XT which features a PCIe 4.0 x8 interface and the Radeon 6700 XT with a PCIe 4.0 x16 interface. This fact is only specified by ASRock with AMD, Gigabyte, ASUS, and MSI not mentioning the PCIe interface on their respective pages. The RX 6500 XT also lacks some of the video processing capabilities of other RX 6000 series cards including the exclusion of H264/HEVC encoding and AV1 decoding.
