is b550 better than x470

[DotzHyper]

Hey, I was wondering if b550 is better than x470. I can only really find comparisons of the same generation.

Thanks

B550 has slightly less SATA&USB, but more and gen+ PCIe, wich can be used for extra SATA/USB.

AND B550 will likely support CPUs further into the future

I just copied the table from here:https://www.gamersnexus.net/guides/3582-amd-chipset-differences-b550-vs-x570-b450-x470-zen-3

it probably doesn't change the conclusion, but there are definitely some errors in it. I can say for sure that B450 supports PCIe gen3, I have no idea about the accuracy of the remaining data

worth noting that some B550 boards do support some PCIe Gen 4, my Aorus Elite B550 V2 runs my 3060ti at PCIe Gen 4
