I had a ASRock b350 and missed the train to upgrade to a 5800x because of the BIOs. If I had a slightly different MoBo I could have upgraded.
Looking for a AM5 board now and putting in a 7600 for now. But looking to see if I can get 8800x3d or hopefully the 9800x3d in 2026.
Generally it’s the mobo chipset that determines which CPUs are compatible. Often the chipsets are compatible with two generations of CPUs, that was the case with H6xx from intel, i got one with an alderlake cpu amd could upgrade it a year and a half later with rocketlake. The mobo OEM needs to support this in their uefi/bios
