AMD B550 to lack PCI Express 4.0 support?

Will motherboards with the upcoming AMD B550 chipset lack PCI Express 4.0 support? It seems so as a new report from HKEPC indicates that the B550 chipset will utilize PCI Express 3.0.

The B550 will reportedly have four native PCI Express 3.0 lanes, which makes it more potent than the X470. The rest of the specifications seem largely identical to the X470.

A separate piece of news was found on HP's website, where users discovered new computers that use the Ryzen 7 3700X in combination with a B550A based motherboard and the unannounced Radeon RX 5300 XT video card. It's not known what the difference is between the B550 and the B550A, but the HP specifications page confirms the B550A will use PCI Express 3.0.

There's no official word from AMD yet, but it could be that at least for the foreseeable future, the X570 will remain the only chipset with PCI Express 4.0 chipset.
