writes the I/O controller in AMD's upcoming Ryzen 3000 "Matisse" processors is made on a 12nm process. Previous reports indicates this controller would be made on a 14nm node. More technical details about Matisse's MCM structure can be found at the site.
It was earlier reported that while the Zen 2 CPU core chiplets are built on 7 nm process, the I/O controller is 14 nm. We have confirmation now that the I/O controller die is built on the more advanced 12 nm process, likely GlobalFoundries 12LP. This is the same process on which AMD builds its "Pinnacle Ridge" and "Polaris 30" chips. The 7 nm "Zen 2" CPU chiplets are made at TSMC.
