It looks like the generation digit corresponds to year for Desktop CPUs too. I think the only major difference from the image I showed prior is the last digit, the desktop CPUs have different letter(s) but the other 4 digits correspond the same. For example, the 7950X is 2023, Ryzen 9, Zen 5, Lower model, and X is high power draw and clock speeds, then there is the 7955WX which is 2023, Ryzen 9, Zen 5, Upper Model (Threadripper), Workstation. The 8950X upcomming cpu is 2024, Ryzen 9, Zen5, Lower Model, High Power and clock speeds, etc. So the 8 series is still Zen 5, so its still a refresh of other zen5 chips, however it also apparently has about a 20% uplift compared to the 7 series, but its still a refresh. So the 9000 series we won’t know if its a refresh or not until we have the skus with the 3rd digit, if its a 6, then its a not a zen5 refresh, if its a 5, it is a zen5 refresh.
