How many pci-e lanes does Athlon 300GE have?

There are doubts.
What about PCIe lanes for chipset?
There are 3 groups of PCIe lanes:

• Discrete GPU
• Chipset
• NVMe SSD

I know that some Athlons have a limited number of PCIe lanes. (Athlon 3000G have only 6 PCIe lanes).

Can be clarified how many PCIe lanes specifically for Athlon 300GE? How is it grouped?

[Qanatoz]

I strongly recommend to ask for Online Service Request because there is no detailed documents about pci-e at AMD website.

As I know storage = NVME+USB+CHIPSET, so only 2 groups.

There said about 20 lanes for PRO version.
