Does the MSI MAG B650 TOMAHAWK support both Zen 4 and Zen 5 processors on the same AM5 socket?

Yes, the MSI MAG B650 TOMAHAWK uses an AM5 socket and supports AMD Ryzen 7000 series (Zen 4) and Ryzen 8000 series (Zen 5) desktop processors. That’s an architecture jump on the same socket — exactly what AMD promised when it moved to AM5.
