B650 and X870: compare the board, not the badge
A chipset describes platform capabilities. The motherboard you buy decides how many of those capabilities are exposed and how its slots and ports are arranged.

Start with the connections you need
AMD's AM5 chipset reference distinguishes capabilities across its chipsets. Use it to understand the platform, then read the exact board manual for implemented USB, storage and expansion support. Avoid assuming that a chipset name guarantees the same ports, networking, lane routing or board layout across different manufacturers and revisions.
Make storage and expansion a joint check
List the drives and cards you plan to use together. A board can share resources between slots, so check the manual's population rules, not only the headline count. An unused connector on a product photo is not evidence that all devices work simultaneously at their highest advertised mode. Keep interface generation separate from the physical connector and lane width.
Choosing without a blanket recommendation
Compare boards against the requirements of your build: exact CPU/BIOS support, memory kit, storage layout, connectivity and case format. A newer or more expensive chipset does not by itself establish a better gaming result. RigPrism's current board records may lack chipset and lane facts; use the source and guide links to complete the manual check instead of reading an empty cell as a feature claim.
Your check before choosing parts
- List simultaneous storage/expansion devices.
- Read exact board port and lane-sharing rules.
- Verify CPU/BIOS and case fit separately.
