AMD released a new Roadmap which shows codenames of upcoming Zen2 and Zen3 processors. From the first look it seems that 2nd Generation Ryzen Threadripper will be succeeded next year by Castle Peak architecture, based on Zen2.
AMD is preparing their next-gen Ryzen processors for 2018, but we’re already hearing about the new 400-series chipset that will power next-gen motherboards thanks to a new post on PCI-SIG. The upcoming Zen+/Ryzen 2000 range is also known as Pinnacle Ridge, and will be an upgrade of Zen 1 made on 12nm (improved 12FF). AMD will give us higher clock speeds and improved power efficiency, which is always welcomed. Zen 2 will be saved for the Ryzen 3000 series of processors, which will offer even more improvements over Zen as it will be baked onto the super-delicious 7nm node.
AMD’s upcoming Summit Ridge 300 series chipset was listed on PCI-SIG in January 2016, but now we have the new codename Promontory chipset listed on PCI-SIG, which was added on December 19, 2017. This new chipset teased “AMD 400 Series Chipsets” which will include X470, B450, and A420 series motherboards.
