Looking at the diagram, we see the CPU serving up 24 PCIe 4.0 lanes, with 16 of them jettisoned to two PCIe x16 slots for graphics cards. Those slots can be configured as either PCIe 4.0 x16 or x8/x8.

As previously leaked, the new diagram reveals the Arrow Lake-S CPU and motherboards will support 16 dedicated PCIe 5.0 lanes for graphics cards.

It's clear already that Ryzen 3000 CPUs (Matisse) and the X570 chipset will support PCIe 4.0. The new diagram once again confirms that the processor will provide a total of 24 PCIe 4.0 lanes.
