What AMD's 64-core 'Rome' server CPU tells us about Ryzen 2

AMD’s Ryzen 2 consumer CPU isn’t coming until 2019, but we saw hints of what to expect in “Rome,” the 64-core server CPU AMD unveiled on Tuesday. It’s based on a new 7nm Zen 2 core that’s likely to find its way into Ryzen 2 next year. Let’s take a closer look.  Each Rome CPU will feature 64 cores with symmetrical multi-threading for 128 threads per socket. The CPU itself is “revolutionary,” AMD said, and is built around eight separate 7nm “chiplets” with eight cores each.The chipsets contain no memory controller or PCIe, but are instead tied to a central IO chip built on 14nm. The IO chip has 8 channels of DDR4 plus support for PCIe 4.0. The company connects each chiplet to the IO chip via a 2nd-generation reduced latency Infinity Fabric. To read this article in full, please click here
