AMD launched the new Ryzen 3 3100 and Ryzen 3 3300X and shared the Socket AM4 roadmap, revealing next gen “Zen 3” desktop processors will be compatible with AMD B550 and X570 chipsets.

Ryzen 3 pricing details are as below:

Ryzen 3 3100S$151 (inc/ex Tax)
Ryzen 3 3300XS$181 (inc/ex Tax)

Back in 2016, AMD promised that the AM4 socket type will remain at least till year 2020 and they have delivered that promised. The new B550 chipset will continue to power the AM4 processors with the same socket type.

In the past 4 years, AMD has improved from :

4X more cores and 8X more threads (4C4T → 16C32t)
4X architectures (“Excavator” → “Zen” → “Zen+” → “Zen 2”)
4X process technologies (28nm → 14nm → 12nm → 7nm)
4X PCIe bandwidth (12x PCIe Gen 3 → 24x PCIe Gen 4)
+33% DRAM bandwidth (DDR4-2400 → DDR4-3200+)

What abt ZEN 3 architecture in future ? AMD has confirmed that it will support on the X570 and B550 chipset. Motherboards will require a BIOS update to support that. Unfortunately, the earlier X470 and before won’t be able to suppot the Zen 3 architecture. Check the FAQ below

Q: Will the “Zen 3” architecture be compatible with AMD Socket AM4?
A: Yes! AMD officially plans to support next-gen AMD Ryzen desktop processors, with the “Zen 3” architecture, on AMD X570 and B550 motherboards. This will require a BIOS update. Specific details about this update will come at a later time, but we’re committed to keeping you up-to-date. We’ve also updated our official chipset/CPU support matrix to take future “Zen 3” processors into account (below)!

Q: What about (X pre-500 Series chipset)?
A: AMD has no plans to introduce “Zen 3” architecture support for older chipsets. While we wish could enable full support for every processor on every chipset, the flash memory chips that store BIOS settings and support have capacity limitations. Given these limitations, and the unprecedented longevity of the AM4 socket, there will inevitably be a time and place where a transition to free up space is necessary—the AMD 500 Series chipsets are that time.

Q: How long will Socket AM4 last from here?
A: This will depend on the schedule of industry I/O technologies. Such technology changes typically require adjustments to the pin count or layout of a processor package, which would necessitate a new socket. We have no specific details to share concerning this roadmap or timing right now, but we know it’s important to keep you updated—and we will.

Q: Wait, wait, I have more questions!
A: All shall be revealed in time! For now, we can all focus on what’s at hand: AMD B550 motherboards arrive soon, and we wanted you to rest easy knowing that an investment in this platform gives you a clear upgrade path tomorrow. The same is true for AMD X570 motherboards, too.

Historic upgradeability is what AMD Socket AM4 has been known for throughout its life, and that legacy continues—even now in 2020. So, if you’d like to know more about the AMD B550 chipset, please visit And if you’re interested in building a new gaming rig around AMD B550, motherboards will be available starting June 16th.
