AMD’s CES 2017 meeting room was primarily stocked with untouchable demos: Ryzen populated about half the room, Vega took a small (but critical) corner, and HDR screens took the rest. Given the challenges of demonstrating HDR in any medium other than analog (read: human eyes), we’ll skip that for now and focus on some of the Ryzen information. If Vega interests you, check out our write-up on the basics.

AMD’s suite served as a home to motherboards from MSI, Gigabyte, ASRock, and Biostar. We already spent some time with the MSI motherboards, including a look at the VRM design for each of the two configurations on display, and will today be focusing on Gigabyte’s X370, B350, and A320 motherboards. The company didn’t have any X300 mini-ITX boards at AMD’s suite, unfortunately, but did have micro-ATX displayed alongside the usual ATX form factor motherboards.

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.

The article title might need a few more "-zen" and "-zon" syllables.

AMD’s new Zen architecture today made its public debut under the “Ryzen” 8C/16T CPU, an IGP-less competitor to Intel’s high-end enthusiast platforms. Ryzen, a combination of “Horizon” and “Zen” (we’re told), was demonstrated as operating at approximately 3.4GHz base clock, with boosting capabilities that brought it into competition with Intel’s Broadwell-E i7-6900K.

The Ryzen CPU aims to operate at approximately 3.4GHz base clock, leveraging a form of SMT to achieve 16 logical threads on 8 physical cores. We’ve also learned that Ryzen, due out in 1Q17, will host 20MB of combined L2+L3 cache. We are presently unsure of any more specifics on the caching architecture, and are due for briefings with AMD to develop a deeper understanding of Zen and its cache.
