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

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
