[SOLVED] X570-F vs B550-F Asus ROG

[Isaiah98]

I was hoping to establish the clear difference between these boards and what features justify the $100 AUD price difference.

I understand the X570 board offers support for SLI and has additional USB Ports etc. Is there anything different? I was reading online that the B550 has 3.0 General Purpose Lanes while the X570 has 4.0, I don't really know what that means, unfortunately.

Any assistance is appreciated.

The question here is what are you looking for in your build? Generally the X570 isn't a budget oriented board and comes with a few more extra bells and whistles and by default needs to be built well since the X570 chipset isn't a cool cat.

If you're only going to be dropping in the single most powerful GPU your wallet can afford, then there's no point going for an X570 chipset. In fact you could get away with an A520 board if you only intend to overclock the rams and have a mild overclock on the CPU(provided you have good airflow around the VRM's).

How does your (proposed)build look right now?

So i'm going for a:

3700x
32GB of RAM
RTX 3080
750W PSU
H100I 240mm AIO

...

That full price difference is probably hard to fully justify as it relates as much to market segmentation as anything else. But it's easy to understand why the X570-F should be more costly to some degree for three main reasons:

1: it uses the X570 chipset which not only straight up costs more than a B550 chipset but also requires a big heatsink and a fan, further adding to it's cost.
2: while the B550-F has a fairly robust VRM, the X570-F is VERY robust. Smart power stages aren't cheap and it has a lot of them.
3: the X570-F supports PCIe gen 4 to ALL available slots. AMD certification for X570 requires critical design margins be expanded to assure signal fidelity and that often means use of amplifiers and signal conditioners to provide the margins. The board also might need more layers in construction to give layout options for the designer to assure minimum path lengths. All of that is costly in each of design, materials and manufacture which in turn drives up board cost.

The AIO is just overkill. Even the stock cooler does a pretty decent job. Maybe for a Ryzen 9 I'd say go for the AIO but... come on... It's just way overkill for the 3700x.
