At their Computex 2019 keynote address AMD announced their 3rd generation Ryzen desktop processors family, which is based on the company’s Zen 2 microarchitecture, and makes use of the 7 nm fabrication process from TSMC. These chips are designed for the AM4 socket and are backwards compatible with older 300 and 400-series motherboards. Each chip is a multi-chip module of up to two 8-core “Zen 2” CPU chiplets, a 14 nm I/O controller die that has a dual-channel DDR4 memory controller and PCI-Express gen 4.0 root complex, as well as some SoC connectivity. AMD says these chips have a 15% IPC increase over Zen 1 and higher clock speeds leveraging 7 nm.
The flagship chip is the Ryzen 9 3900X. It features 12 cores, 24 threads with a base clock of 3.6 GHz and a boost clock of 4.6 GHz. It has 72 MB of total cache and a 105 TDP. Performance not only beats the Intel i9-9900K, but also the i9-9920X HEDT processor despite having fewer memory channels. AMD will sell this chip for $499.
Up next is the Ryzen 7 3800X, which is a 8-core, 16-thread part. It features a base clock of 3.9 GHz and boosts up to 4.5 GHz. It has 36 MB of total cache and the same 105W TDP. This chip will have an MSRP of $399.
Finally we have the Ryzen 7 3700X which is also an 8-core, 16-thread part. It has a base clock of 3.6 GHz and boosts up to 4.4 GHz. It has 36 MB of total cache and a TDP of 65W. It will go on sale for $329.
All three of these chips will go on 7/7/2019.
The Ryzen 3000 series is the first mainstream processors to support PCI-Express 4.0.
