AMD B550 Vs. X570 Motherboards: Which One to Buy?

Written By Steven Arends
Our Verdict: Both the B550 and X570 motherboards are suitable for any top-class gaming build. The B550 boards are more suitable for regular gaming builds that you can build with a reasonable budget. Whereas, the high-end builds that require extra storage for video editing are suited to X570 boards.

The release of the much-awaited B550 motherboards ended all the anticipation. These motherboards are the upgrade of motherboards with B450 chipsets.

That said, the range of B550 motherboards is quite diverse. You’ll find cheap budget-oriented options as well as boards with high-end features.

But the question is, are B550 motherboards better than X570 boards?

Don’t worry. This post is curated explicitly for answering this question. Here, I am going to simplify the differences between these two chipsets.

So, let’s waste no time and dive straight into the discussion.

Is X570 better than B550?

In technical terms, a motherboard with an X570 chipset is better than a motherboard with a B550 chipset. But in terms of reasonability, the B550 board is better.

You may ask:

Is X570 more future-proof?

No, the X570 motherboards aren’t future-proof. It is an end to the AM4 lineup, and the presence of more PCIe 4.0 slots doesn’t make a difference to most users.

Here are the five differences between the B550 and X570 motherboards:

1. Compatibility

The first thing to consider while comparing motherboards with different chipsets is whether they are compatible with your desired CPUs.

Not all motherboards support all types of CPUs. Depending on the chipset types, the compatibility differs across various models.

That said, the moboards with B550 chipsets come with good compatibility. These boards are compatible with Ryzen 3000 CPUs and beyond. Check out the comparison between NZXT Kraken Z63 & Noctua NH-D15.

That eventually means a B550 motherboard supports most CPUs under the Ryzen 3000 and Ryzen 5000 series. However, this B550 motherboard doesn’t support Gen 1 and Gen 2 CPUs from Ryzen.x570-vs-b550-motherboards-comparison

Another thing you need to note down is that these B550 boards also don’t have APU’s that come under the Ryzen 3000 series.

Now, in the case of the boards with the X570 chipset, there isn’t any issue with the compatibility of APUs. Also, they are compatible with the Gen 2 CPUs, that is, the processors under the Ryzen 2000 series. But these boards are limited to Ryzen Gen 3 CPUs, unlike the B550 boards.

Therefore, if you look beyond Ryzen Gen 3 CPUs, then it’s B550 moboards you should go for. Other than this, you can settle with an X570 motherboard.

2. PCIe 4.0 Support

The presence of the PCIe 4.0 interface in your motherboard does make a difference. It results in facilitating the high-speed data transfer from GPU, SSDs, and other expansion cards.

In the moboard, the presence of PCIe 4.0 means that your board can have a max bandwidth of 16 GT/s per lane instead of 8 GT/s that you can get from the PCIe 3.0 interface.

It eventually means that you’ll get the advantage of using extra lanes for extra SSD slots.

Now, the PCIe support for the motherboards with B550 and X570 chipsets isn’t the same. Check out the comparison between NZXT Kraken Z63 & Corsair iCUE H115i Elite Capellix.

The most significant difference is that the B550 moboard connects the processor using the 4-lane PCIe 3.0 connection, whereas the board with the X570 chipset uses PCIs 4.0. And that is because the boards with PCIe 4.0 have more lanes.

Eventually, it results in the addition of 16 PCIe 4.0 x16 lanes to the X570, but the B550 possesses none.

Though, for the B550 boards, PCIe 4.0 connectivity will work on the CPU directly using the primary PCIe x16 and also the M.2 slots. That means B550 moboards can use PCIe 4.0 for two devices, an upgrade from the B450 boards. Also, see our expert’s recommended fastest 4.0 PCIe SSD.

Other than this, the X570 boards support dual PCIe 4.0 M.2 slots. The B550 is also compatible with multiple ones, but only one of them would be supported by PCIe 4.0.

3. Connectivity

Since there is a difference in the number of PCIe 4.0 in the boards with B550 and X570 chipset, the difference in connectivity is also prevalent between them.

That said, the X570 board consists of 8 more USB 3.0 ports than that of the B550 board.

Also, if you want motherboards that provide you a reasonable number of storage options, the board with the X570 chipset is a better option. As you will get additional 8 SATA ports on the X570 board, which can be reconfigured. Check out our expert’s recommended best RAM for Ryzen 9 5900x and Ryzen 9 5950x RAM.

4. VRM Power Phases

In the motherboard, the VRMs make sure that stable power is delivered to the CPU so that your processor remains in good health. The outcome here is the utilization of the maximum potential of the CPU.

That said, the more the number of VRMs, the better it is. The board will have better control over the power delivered and lessens the load on VRMs.

Now, between the X570 and B550 motherboards, the number of VRMs is higher on the X570 ones. And the main advantage here is that it allows the overclocking of powerful processors with stability.

Therefore, for squeezing out most of your system using a powerful processor, an X570 motherboard has the edge over the B550.

5. Price

Lastly, price plays a huge part when you consider the buying decision. The motherboards with X570 chipset are more premium options with extensive features compared to the B550 boards.

So, if you want to build your rig around a high-end processor like Ryzen 9, the X570 chipset is a perfect choice. Or else, for a cheap and mid-range option, the B550 motherboards are good to go with.

Is X570 worth it over B550?

If you ask whether X570 boards are better than B550 boards, I would say yes. But in terms of mass appeal, I would say no.

For any regular build, the features present in a moboard with a B550 chipset are more than enough. That said, a B550 board is almost like the X570 board aside from a few differences.

Now, an X570 board consists of various fancy features that won’t give any good advantage for any build. Unless you focus on building a high-end video editing system, it’s no use to use such a powerful board.

Final Thoughts

So that is the overall breakdown of the fundamental differences between motherboards with the B550 and X570 chipset. After reading this article, you’ll be able to find out the differences that exist between them.

Lastly, I hope that you would be able to choose the correct motherboard for your build. In case any confusion arises about anything, do let me know in the comments.
