Technically speaking, with the (much belated) launch of the AMD B550 motherboard platform, while it supported their 3rd-gen processor releases (and new platforms moving forward for the immediate future) it did come with a notable caveat. Namely, that it didn’t, at least in terms of what AMD said, support their older 1st and 2nd-gen Ryzen releases.

In a report via TechPowerUp, however, images taken from an ASUS B550 motherboard (specifically, the TUF Gaming B550M-Plus) have appeared online apparently debunking that position!

The ‘3rd-gen only’ aspect was AMD’s official line on the subject in regards to their B550 motherboard releases. As such, I guess many presumed that it was accurate and/or didn’t bother trying out a few models to see if anything stuck.

Well, following the images below being release, it does seem to indicate that, at least for the Ryzen 2600X and 3400G APU there is some degree of compatibility. Certainly enough to actually get the system to boot up which is, quite frankly, 90% of the battle.

What Do We Think?

Before you go rushing out to buy a B550 motherboard for your 2nd-gen Ryzen processor, we should note that, at the time of writing, the B450 or X470 is still, by a massive margin, your most preferable option. In addition, while this ASUS TUG Gaming B550M-Plus motherboard does seem to work, that may not be the case for many of your alternative options.

We should also note that these images did not reveal any 1st-gen Ryzen platforms being functional. Something one would presume would’ve been noted if it had. It is, therefore, a notable curiosity to say the least. I wouldn’t let it lead you into making any hasty purchases though!

I just was wondering why this chipset doesn't support older generation ryzen cpu's. Is there a technical reason that I don't know of. I was troubleshooting a board with a 3900x in it and I had a spare r5 1400 cpu and I was going to use it to test the board but I realized that the cpu isn't supported on b550 chipsets. I was just wondering. It seems odd to have the same socket and not be able to use older processors. Do any of you very smart people know why?
If the mobo is not very new, it was probably launched with support for older CPUs. You can just flash the older BIOS and you will get support.

But yes, a lot of people took AMD's promise at face value and disregarded the numerous technical hurdles you have to overcome to reuse the same mobo for many generations of CPUs. Those same people seem a little confused, now that reality caught up ;)

No, B550 doesn't even support 2nd Gen Ryzen, only 3rd Gen/3000 series, and the upcoming 4th Gen 5000 series Zen3 CPUs.

X570 doesn't support 1st Gen, only 2nd, 3rd and 4th gen. The reason why, is mainly because of BIOS limitations. Also because of architectural limitations. In the simplest terms possible, there are features on X570 and B550 that the 1st Gen Ryzen processors were simply not designed to support, and therefore they can't be used on those motherboards. It is a question of HOW the processors were designed, and they were not designed to be compatible with some aspects of the newer chipset designs like the 2nd and 3rd Gen CPUs were, and even were not, in the case of 2nd Gen not being compatible with B550 boards.

To some degree it is also probably a matter of AMD and board manufacturers not wanting to lose out on being able to sell newer models as well.

In truth, these boards don't really offer ANYTHING important, for now anyhow, over B450 models, except for PCIe 4.0 support, which 1st Gen Ryzen CPUs do not have, and cannot have, but which doesn't really offer any gains even with CPUs that do support it when paired with PCIe 4.0 NVME drives and graphics cards, so you are just as well off using a good B450 board anyway with that CPU.

When AMD’s excellent Ryzen 3000-series processors released last summer, snatching the desktop computing crown from Intel, one of their key features was support for the blazing-fast PCIe 4.0 interface—but only if you purchased a pricey X570 motherboard, too. No more. After months of constant leaks (and constant pining by enthusiasts) AMD confirmed Tuesday that it’s bringing PCIe 4.0 to the masses with the announcement of B550 motherboards, revealed alongside two extremely affordable new Ryzen 3-series processors.

The twist? Motherboards with the B550 chipset aren’t launching until June 16. But if you’ve already waited this long without splurging on an X570 upgrade, what’s another couple of months?

Update: The other twist, revealed on the day that Ryzen 3 3000-series processor reviews lifted? B550 boards won’t support older 1st- and 2nd-gen Ryzen processors. They’re only support 3rd-gen Ryzen 3000 chips, along with later chips built using AMD’s forthcoming “Zen 3” architecture. Older chips don’t support PCIe 4.0 and will be well-served by existing B450 boards. On the bright side, the mainstream B550 boards support a full 20 usable PCIe 4.0 lanes, so you’ll be able to run both a PCIe 4.0 SSD and a PCIe 4.0 graphics card if you desire.

AMD will continue to support the AM4 socket going forward, but chipset support is getting…complicated. Read about it here. Our original story continues below.

B550 motherboards are exactly what you expect: They’re like the existing B450 mainstream Ryzen motherboards, built around the backward-compatible AM4 socket, but with support for PCIe 4.0 included. The cutting-edge interface promises faster speeds for any device that taps into it, but it’s especially beneficial for storage. PCIe 4.0 SSDs hit ludicrous speeds—and this first wave doesn’t even come close to maxing out the technology’s potential. Check out our PCI 4.0 primer if you want to know more.

It remains to be seen just how expensive the new boards are, however. PCIe 4.0 achieves a lot of its speed increases through faster clock speeds, which means more heat. Existing X570 motherboards pretty much universally include enhanced heatsinks and even dedicated chipset fans to tame temperatures. If B550 boards need similar hardware, they’re sure to be more costly than prior generation x50-class Ryzen boards.

Ryzen 3 gets company

You need to pair PCIe 4.0 motherboards with a Ryzen 3000-series processor to unlock their fantastic speeds, and to that end, AMD also announced a pair of inexpensive 7nm 3rd-gen Ryzen 3 processors today. The $99 Ryzen 3 3100 and $120 Ryzen 3 3300X are both four-core, eight-thread chips, rated for 65 watts and with full PCIe 4.0 support in tow. The cheaper Ryzen 3 3100 sports a 3.6GHz base clock and 3.9GHz boost clock, while the Ryzen 3 3300X ups speeds to 3.8GHz base and 4.3GHz boost for $20 more. Look for both to land in May, well ahead of B550, oddly enough.

Unlike Intel’s Core i3 processors, Ryzen 3 chips lack integrated graphics, so you’ll need to pair the new chips with a discrete graphics card.

The burning question: How will AMD’s quad-core, 3rd-gen Ryzen 3 chips stack up against the $85 Ryzen 3 1600AF, a still-available budget barnstormer that packs six cores and twelve threads, but at lower frequencies (and without PCIe 4.0)? The wait for benchmarks shouldn’t last long. 

Update: The new CPUs look pretty damned good, according to reviews from Hardware Unboxed, Tom’s Hardware, Anandtech, and others—particularly the $120 Ryzen 3 3300X, which holds its own against Intel’s older Core i7-7700K flagship. The 7700K was Intel’s last four core, eight thread champion and cost $350 when it launched in 2017. We haven’t reviewed the new processors yet but have them in hand. 

Editor’s note: This article originally published on April 21, 2020, when the new parts were announced, but was updated on May 7 with new information.

AMD B550 Motherboards Spotted Running Zen and Zen+ CPUs

AMD’s B550 chipset motherboards are explicitly not compatible with first- and second-gen Ryzen chips, but according to a new series of tweets from known tech detective @momomo_us, the boards have been spotted running older Ryzen processors. The CPU-Z screenshots and results, which are in the CPU-Z database, seemingly confirm that someone got the older CPUs to run on a new MSI MAG B550.

Momomo_us posted screenshots that seemingly confirm an AMD Ryzen 3 2200G, AMD Ryzen 5 1600, and a Ryzen 5 3400G APU running on the B550 motherboard. All of these processors use AMD’s older Zen and Zen+ microarchitectures.

None of these processors are on the B550’s CPU support list, nor does the change log mention additional support for older processors. According to the B550’s packaging badge, it only officially supports 3rd generation Ryzen Matisse CPUs (Zen 2) as well as upcoming Renoir (Zen 2) and Vermeer CPUs (Zen 3). 

We’re not sure why you would bother updating to a new motherboard to use an old processor, but it’s nice to know that you could, at least theoretically. However, it's highly likely that these tests were run by a motherboard vendor that could circumvent the compatibility restrictions for the sake of science, and it's unlikely that we would see B550 boards with unrestricted AM4 compatibility hit the market.
