difference between x570 and b550

[Cyneptic]

so i am getting a 3900XT and ive been wondering what is the difference between x570 mobos and b550. as i find b550 to be much more affordable but dont really want to lose performance over it.

The main difference is that X570 allows the lanes that are wired to the chipset and to the cpu to be gen 4 assuming you're using a zen 2 chip, with b550, it allows the lanes that are wired to the cpu to be gen 4 but the lanes that are wired to the chipset are gen 3, unless you need the extra gen 4 lanes, b550 is just as good. 

Budget for a board? location and currency? also the XT lineup are not worth the extra money, so you could just go with the 3900x unless it was similarly/ the same price.

it is quite a similar price here so I may aswell go with the XT, i have somewhere between 180 to 250-80$ for the budget (for currency go with USD) but I would really like to save on it if it doesn't mean performance drop since I'm saving for a 3080

 

I was thinking between rog strix b550-f and x570 aorus elite. but even though i can go for rog stix x570-f I rather save that for gpu unless it means performance drop.

With both B550 and x570 the pci-e x16 slot in which you normally insert a video card, and the first m.2 connector can run in pci-e 4.0 mode. 

 

The difference is in the extra 8 pci-e lanes produced by the chipset, which usually go to the bottom pci-e x16 slot (only x4 electrically) and the 2nd m.2 connector.  

On B550 chipset, these 8 pci-e lanes are pci-e 3.0, on x570 they're pci-e 4.0 lanes. 

 

B550 also doesn't need a chipset fan, x570 has chipset fan but it's pretty much only working if you have pci-e 4.0 devices connected to its chipset lanes.

For the board? 

If so..

To name some boards, these are all decent, or the x570 tomahawk if you can find one since they're usually hard to find.

yes I meant for the board. the one available with a really good price is rog strix b550-f gaming. unfortunately i couldnt find tomahawk

so with b550-f gaming can I maxout the performance from 1 graphics card and 1 nvme with pcie 4.0?

Yep, assuming they are gen 4 devices, and assuming you're using the first m.2 slot and the first x16 slot (they are wired to the cpu) it'll run at gen 4.

I don't think this is 100% accurate. For example, the second m.2 connector on the "gaming edge" board is only pci-e 3.0, while on the "tomahawk" it's 4.0. The question is why.

No idea why they rate it as pci-e 3.0 only. May be due to the use of that ASM1061 sata controller, I don't know. 

 

The chipset is pci-e 4.0, and has 8 pci-e 4.0 lanes... if a mobo maker decides to add a pci-e switch or multiplexer that can only do 3.0 , or for some reason derates some component on board to 3.0 only ... it's not chipset's fault.
