AMD's second-generation Ryzen CPUs came out just a few weeks ago, and they were accompanied by a range of brand-new X470 motherboards for high-end system builders. The X470 chipset doesn't actually add any new features or upgrade any connectivity standards compared to X370, though. While the underlying chipset silicon might consume less power, that's about the only tangible improvement in the Promontory chip that underpins all AM4 chipsets. X470 might be more about improving the supporting infrastructure around the AM4 socket for the potentially higher power demands of AMD's latest chips, although even this rationale falls a little flat. AMD says all of the X370 motherboards on the market can stand up to the power demands of second-gen Ryzen CPUs.As AMD put it to me, X470 is a "harmonized" release for second-generation Ryzen CPUs. Ultimately, companies need new products to catch builders' attention, and the X470 name means builders are getting the fruits of a year
