[Update] - added new graphic, possible official AMD slide.

"AMD X570 is the company's first in-house design socket AM4 motherboard chipset, with the X370 and X470 chipsets being originally designed by ASMedia. With the X570, AMD hopes to leverage new PCI-Express gen 4.0 connectivity of its Ryzen 3000 Zen2 "Matisse" processors."
"On the AM4 "Valhalla" platform, the SoC puts out a total of 24 PCI-Express gen 4.0 lanes. 16 of these are allocated to PEG (PCI-Express graphics), configurable through external switches and redrivers either as single x16, or two x8 slots. Besides 16 PEG lanes, 4 lanes are allocated to one M.2 NVMe slot. The remaining 4 lanes serve as the chipset bus. With X570 being rumored to support gen 4.0 at least upstream, the chipset bus bandwidth is expected to double to 64 Gbps.
Since it's an SoC, the socket is also wired to LPCIO (SuperIO controller). The processor's integrated southbridge puts out two SATA 6 Gbps ports, one of which is switchable to the first M.2 slot; and four 5 Gbps USB 3.x ports. It also has an "Azalia" HD audio bus, so the motherboard's audio solution is directly wired to the SoC. Things get very interesting with the connectivity put out by the X570 chipset."
Am I seeing this correctly, so up to 3 32Gbps M.2 slots? Two possible from the chipset, one from CPU?
