NEW MSI B550 UNIFY better than X570 UNIFY??

https://www.msi.com/Motherboard/MEG-B550-UNIFY? VS https://uk.msi.com/Motherboard/MEG-X570-UNIFY (tomahawk too)

B550 14+2 power stages 90A
X570 12+2 power stages 60A

Both have PCIe 4.0, Triple Lightning Gen4 x4 M.2 so same number of general purpose lanes?

I'm getting 5900x / dark group 16gb cl14 3600mhz

any reason to get the x570 over the b550?

only reason I can think of is latency from chipset if any? but VRMs better on mature not yet released b550.

Or shall I just bite the bullet and go for dark hero?

The B550 unify is showing 3 out of 4 m.2's PCI - 4 along with 1 graphics slot.

I would only use 2 m.2's max anyway so should be good for me.

says CPU support mode providing its zen 2 or 3 should have support for it.
Looks like you're getting the lanes direct from the CPU.

B550 unify
+ no active cooling on chipset
+ better VRMs
+ impressive overclocking
+ more mature high quality board
+ 1 more m.2 slot @ pci 3
3 of the m.2 4.0 slots are direct from CPU (won't it provide latency benefit from the b550 unify M.2S direct to CPU rather than running through the chipset on x570 or is it any tax/downside on the cpu over chipset?)

X570 unify
+ more pci 4 general purpose lanes

2 of the m.2 4.0 slots are passing through chipset


For me, ill only ever have 1 graphics card and max 2 m2s plugged in. seems like b550 the better choice for me!?

Seen the X, but won't be worth getting for most of us.
