AMD Zen 6 CPUs Appear in Linux Kernel - EPYC Venice and Weisshorn Confirmed

The Linux kernel code has started to show Unique identifiers for CPUs with Zen 6 architecture, which indicates the advancement of AMD's new EPYC Venice server chips. According to an analysis of patches published by community members, CPU IDs with Zen 6 flags have been added to the system, including the identifier "0x50" which directly refers to the Venice platform. The internal code name for these workstations is Weisshorn, and they are focused on high-performance solutions in the data center and AI segment.

At this stage, AMD's main focus is on server and HPC products, while desktop lines like Medusa Ridge will appear in patches later. In parallel, work is underway on variations of Venice-Dense and AMD Instinct accelerators, which can also use the Zen 6C architecture. This confirms that Zen 6 will be used to produce both classic and energy-efficient cores, adapted to different types of computing loads.

According to preliminary specifications, EPYC Venice server processors will be manufactured using the 2 nm process technology (TSMC N2) and will be able to have up to 256 cores and 512 threads, located on eight CCD chiplets. Medusa Ridge Desktop Processors based on the same architecture will appear later and will offer configurations of up to 32 cores. The inclusion of Zen 6 in the Linux kernel indicates that the architecture is preparing for an active testing and debugging phase long before the announcement in 2026.
