AMD and Intel launch mainstream and budget motherboard chipsets at CES but some of the codenames are so similar that I've already mistaken them for each other
It's taken a while to happen, especially in the case of AMD, but at long last, we're seeing new mainstream and budget motherboards for Zen 5 and Arrow Lake processors at CES. The stars of the show sport the B850 and B860 chipsets, but given that the names are almost identical, there's probably going to be no end of confusion resulting in products being returned to retailers. That's because B850 is AMD-only and B860 is Intel-only. Obviously.
In the case of the former, AMD actually announced the B850 chipset back in July 2024, with the launch of the Zen 5 CPU architecture, but it's taken until now for motherboards using it to appear. ASRock, Asus, Gigabyte, and MSI are all showing off new models at CES, and I have one in for testing already.
While AMD X870/E motherboards all come with PCIe 5.0 graphics card and primary SSD slots, B850 boards are only required to support PCIe 4.0 for both as standard, though many offer Gen5. It's a similar story regarding USB4—mandatory for X870/E boards, optional for B850.
In some cases, it can be quite confusing. Take Asus, for example, and its ROG Strix B580 motherboards. The B850-E Gaming WiFi has a Gen5 GPU and SSD slot (the rest being Gen4) and a 40 Gbps USB4 port; the B850-F Gaming WiFi has the same Gen5 slots but no USB4 port, just a 'normal' 20 Gbps USB.
And there's the B850-A Gaming WiFi with a Gen5 graphics card slot, but no Gen5 SSD slot or USB4 port. Ah but then there's the B850-I Gaming WiFi that has a Gen5 GPU slot, two Gen5 SSD slots, and no USB4.
To be fair to Asus, it's not the only motherboard vendor that has a large number of very similar but confusingly specified models. But what's making it all worse is the fact that Intel's new mainstream chipset for its Core Ultra 200S processors is called B860.
The similarity between the codenames means that there are certainly going to be cases where someone accidentally orders the wrong motherboard—the best-case scenario just results in a quick return to the retailer, and the
