What PCIe slots are available on the Gigabyte B650 AORUS ELITE, and what are their configurations?

The primary x16 slot runs at PCIe 4.0 x16 from the CPU. A second PCIe 4.0 x16 slot runs at x4 through the chipset. There’s also a PCIe 3.0 x1 slot for smaller expansion cards. Everything is Gen 4 or better — no last-gen bottlenecks.
