Despite the general lack of official documentation on AM4, we were able to get hands-on with some early AM4 motherboards from MSI at CES 2017. This is the first time – from AMD or from others – that we’ve received any detail on the new AM4 products, and the first time they’ve been demonstrated in public. The company debuted its X370 XPOWER Titanium overclocking motherboard (For Ryzen) alongside a mid-range B350 Tomahawk board, neither yet adorned with a price. We do have a release date target, though.

During PAX Prime 2016, we posted some official documentation on lower-end AM4 chipsets that would ship to bulk buyers, for use in HP-like systems at Costco-like places. Since then, we’ve learned that the X370 platform will crown the AM4 chipset accompaniment, with B350 falling next under that, and A320 (already known, see: PAX) at the low-end. A320 would be comparable to A68, were we to draw parallels to previous generation platforms. From what MSI tells us, an X300 chipset will also exist, but is not responsible for lane assignment and I/O tasking in the same way that X370 and B350 are; instead, X300 will likely see exclusive use on SFF platforms, and will perform no substantial functions. This was also detailed in our PAX coverage.
