They are, spec for spec, model for model, but this is the exact reason why I'm not listing the most expensive B550 boards. I don't see why anybody willing to spend £250+ on a board would choose B550 over X570 for the sake of another £20-30.Isn't the b550 meant to be 'cheaper' than the x570?
The fact is, the the B550 chipset is not much "cheaper" than the X570 because what it offers is so similar. As I said earlier B550 is NOT a B450 replacement, it's supposed to sit in between.
