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.
AMD has given its word to support AM5 til 2025
AM5 was released with the 7000 series CPUs. 8000s are absolutely going to be supported, and there’s a very high chance 9000 will be supported as well. I believe AM4 was supported for 4 generations of CPU.
Chances are you won’t conclusively know which CPU is supported until they are released, but to keep the odds ever in your favor you should pick a higher generation chipset. Unfortunately, it looks like only the 6xx generation are released at the moment so there’s not much choice.
