WCCF Tech reports fresh AMD Zen 3 architecture microcode got added to the Linux kernel:
The latest code adds EDAC (Error Detection and Correction) support for AMD's Family 19h which refers to the Zen 3 architecture while the Zen 2 architecture was referred to as the Family 17h. It also states that the existing Family 17h functions can be used for Family 19h, while also allowing family 19h to automatically load the module. The full kernel code can be seen here and here. The timing of this code's appearance is particularly interesting as AMD hasn't yet officially announced any new detail at any major event with CES 2020 being the last where we were expecting to hear more about Zen 3 architecture or the respective products.
While the site writes that this indicates that Zen 3 is coming near, previous rumors indicated that the launch of AMD's Ryzen 4000 series is still far removed from us. Based on what we know, the launch is likely slated for late 2020.
