How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

ASUS ROG STRIX B850-A GAMING WIFI4 M.2 storage positions; 2 SATA 6 Gb/s ports

Manufacturer specification · Only M.2_1 is listed as PCIe 5.0 with Ryzen 9000/7000; M.2_2 uses PCIe 4.0. Ryzen 8000 changes the first connection to PCIe 4.0 and can limit M.2_2 to x2. Using PCIEX16(G4) disables M.2_3.

ASUS ROG STRIX B850-E GAMING WIFI5 M.2 storage positions; 4 SATA 6 Gb/s ports

Manufacturer specification · Using M.2_2 or M.2_3 reduces the primary graphics slot to x8; both M.2 positions are unavailable with Ryzen 8000. PCIEX16(G4) and M.2_4 share lanes: using the expansion slot disables that M.2 position.

Explore the full specifications

Plan the complete platform. Check the exact CPU-support list, required BIOS and memory validation before buying. PCIe generations and lane allocations can change with the processor. A socket match or slot count is not a guarantee that every component works together at its highest advertised setting.
