AMD CEO Dr. Lisa Su at her 2019 Computex keynote address announced the 3rd generation Ryzen desktop processor family, which leverages the company's Zen 2 microarchitecture, and are built on the 7 nm silicon fabrication process at TSMC. Designed for the AM4 CPU socket, with backwards compatibility for older AMD 300-series and 400-series chipset motherboards, these processors are multi-chip modules of up to two 8-core "Zen 2" CPU chiplets, and a 14 nm I/O controller die that packs the dual-channel DDR4 memory controller and PCI-Express gen 4.0 root complex, along with some SoC connectivity. AMD claims an IPC increase of 15 percent over Zen 1, and higher clock speeds leveraging 7 nm, which add up to significantly higher performance over the current generation. AMD bolstered the core's FPU (floating-point unit), and doubled the cache sizes.
AMD unveiled three high-end SKUs for now, the $329 Ryzen 7 3700X, the $399 Ryzen 7 3800X, and the $499 Ryzen 9 3900X. The 3700X and 3800X are 8-core/16-thread parts with a single CPU chiplet. The 3700X is clocked at 3.60 GHz with 4.40 GHz maximum boost frequency, just 65 Watts TDP and will be beat Intel's Core i7-9700K both at gaming and productivity. The 3800X tops that with 3.90 GHz nominal, 4.50 GHz boost, 105W TDP, and beat the Core i9-9900K at gaming and productivity. AMD went a step further at launched the new Ryzen 9 brand with the 3900X, which is a 12-core/24-thread processor clocked at 3.80 GHz, which 4.60 boost, 72 MB of total cache, 105W TDP, and performance that not only beats the i9-9900K, but also the i9-9920X 12-core/24-thread HEDT processor despite two fewer memory channels. AMD focused on gaming performance with Zen 2, with wider FPU, improved branch prediction, and several micro-architectural improvements contributing to a per-core performance that's higher than Intel's. The processors go on sale on 7/7/2019.
