Platform Differences
B550 (AM4) supports Ryzen 3000/5000 with DDR4 and PCIe 4.0. B650 (AM5) supports Ryzen 7000/9000 with DDR5 and PCIe 5.0 SSD support. AM5 is AMD’s current and future platform, while AM4 has reached end-of-life.
B550 — Budget Gaming Champion
B550 with a Ryzen 5 5600 offers exceptional gaming value. The platform is mature, stable, and cheap — B550 boards start at £70 and DDR4 RAM is 30% cheaper than DDR5. For budget builds focused on 1080p/1440p gaming, this is hard to beat.
B650 — The Future-Proof Choice
B650 with a Ryzen 7 7700X costs 40-60% more than a B550 build but offers DDR5, PCIe 5.0, USB4, and a clear upgrade path to future Ryzen processors. For new builds where longevity matters, B650 is the recommended platform.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
