5900x; b550 vs x570

[WhereHere1]

I really don’t know which to get.

or what the main different is.

would I see a difference with this cpu?

It makes no difference to CPU performance. The main different is on X570 all your M2 slots can be PCI-E 4 where as on B550 only one is.

I have two NVMe drives, probably get another at some point. I have a 3080 too.

Is there a massive difference between the two boards? Because the ones I’m looking at are similar priced, but the b550 boards look aesthetically cooler haha xD

I believe if you get 3 nvme it knocks the gpu down to 8 x instead of 16 x just so you know

Depends on the board, something like the B550 Aorus Master has 3 X 4.0 M2 slots (if you use all of them it obviously reduces the GPU to 4.0 x8 though due to a lack of lanes).

A 3080 wouldn’t be limited at 4.0 x8 (effectively 3.0 x16) though so it wouldn’t matter. Some of the B550’s have very high end VRM solutions as well.

With B550 board two NVMes is max before something else has its bandwidth cut.
Chipset simply lacks PCIe lanes.
X570 has enough PCIe lanes for three NVMes without needing to take them from graphics card.
Also with PCIe slot adapter even x1 slot would still give 2GB/s bandwidth for PCIe v4 drive.

Are you sure as i asked this and was told even the x570 useing 3 nvme would knock down gpu as you i thought it didnt but when i asked was told it did is it just certain boards it doesnt do this i even asked somebody who was useing 3 and he said it knocks gpu down to 8x on a x570 ultra board

Unless you're doing workloads that require a lot of large storage transfers between 2 or more super fast NVMEs then B550 will be absolutely fine.

 

[SurfXombie]

Essentially nothing for your CPU, assuming you pay for enough vRam support.
It is in the other features where it shows and the builds tend to be better (like 6 layer PCB).

Basically

• If you just game, and want the budget option go B550.
• If you have wider storage and I/O needs and/or want quality go X570.

While a budget B550 is still not that cheap (~£120) a good quality B550 (~£160) is getting close to the price of a decent X570 (~£210), so if you don't want to skimp just get the X570.

If you are paying for a 5900x then you are not cost conscious, so get the X570

X570 chipset itself has enough PCIe lanes (16) for two x4 slots without need to steal from anything else.
B550 has only 10 PCIe lanes, which gets short after adding all the different controllers etc.

Now if motherboard maker ****s it up by putting third M.2 slot to share CPU's PCIe lanes that's their fault.

 

[Figo]

The B550 range is really good. If you are looking at low end X570 or a B550 for the same price, chances are, the B550 will be the better built board - even though the features are a little cut back

Yeh so do you know what board supports all3 nvme without limiting the gpu mate im not trying to disagree with you as i thought like you that x570 handles all 3 without restricting anything just disabled a couple of sata slots

 

[rare]

X570 Aorus Master? / MSI Unify

MSI X570 Unify could actually take fourth NVMe using adapter in that lowermost PCIe slot.
Having only four SATA ports frees chipset IO lanes to other uses.

And even "lower" end X570 boards like X570 Aorus Elite could take third NVMe in that chipset connected x4 slot.
While even x1 slots would give that still nice 2GB/s bandwidth for PCIe v4 drive using x1 slot adapter.

 

[WhereHere1]

I was looking at the b550 gigabyte vision around £210, similar priced to the lower end x570’s.

 

[rare]

You can get the master for not much more which is a better spec

 

[WhereHere1]

I just check the master is over £300.

how about the aorus elite x570 for just under £200?

 

[mickyflinn]

You need to be clear on what you want if your going to have 3 x m2 nvme drives then your choice should be according.

Ridiculously priced for IO limited B(asic) chipset.
You can use only one M.2 slot (M2A) without halving GPU slot's bandwidth to x8.
Also PCIEX4_2 shares chipset wiring with SATA 4 and 5 ports for last two PCIe lanes.

That's how limited B550 is for making higher end board.
