AMD's Zen 6 CPUs have started to surface on the Linux kernel, as a new patch lists new CPU IDs in the kernel, likely indicating EPYC Venice CPUs.
AMD Continues To Push Zen 6 Enablement Work At Linux, Now Working On Venice Workstation CPUs
Team Red has been active on Linux regarding releasing enablement for its CPUs on the platform, way earlier than other manufacturers. The tradition seems to continue with Zen 6 as well, as according to new patches on the Linux kernel, AMD has listed CPU IDs that are relevant to the next-gen EPYC Venice CPUs, according to @InstLatX64, and interestingly, the CPU IDs correspond to the "Weisshorn" codename, which is said to be AMD's internal naming scheme for Venice workstation CPUs. The work towards Zen 6 is definitely under full force.
#AMD #Zen6 CPUID assignments:
- #Weisshorn B50F00 is Zen6 (probably this is the #EPYC / #Venice due to the similarity to the #Breithorn codename [1])
-B90F00, BA0F00, BC0F00 is Zen6 [1]GitHub:https://t.co/QMdubFadz9

All of these CPU IDs are under the Zen 6 feature flag, which saw enablement a few weeks ago in Linux, and this suggests that, for now, AMD is focused on the professional segment of the market. The "0x50" CPU ID corresponds to Venice, while the other two are said to be for Venice-Dense and AMD's Instinct accelerators, but this isn't confirmed for now.
So, this indicates that all the next-gen enablement work currently ongoing on Linux is targeted towards AMD's AI portfolio, and this includes data center and HPC products. For consumer lineups like "Medusa Ridge", we should expect work to get more intensive in the upcoming months.
For a quick rundown on EPYC Venice, they will use TSMC's N2 (2nm) technology, featuring up to 256 cores and 512 threads, with up to eight CCDs. These processors are said to be one of the best by the company, and with a combination of Zen 6 and Zen 6C cores, Venice is certainly going to be a top-tier release. At the consumer CPU side, AMD plans to introduce "Medusa Ridge" desktop CPUs on the architecture, which will come in 12, 24, and 32 core configurations.
