In a report published by ChinaTimes, it is stated that AMD is all set to leverage TSMC's 3nm process node for the production of its Zen 5 powered next-generation EPYC and Ryzen CPUs. The 3nm AMD Zen 5 architecture will be replacing the 5nm Zen 4 architecture that is expected to launch next year with EPYC Genoa and Ryzen 7000 'Raphael' CPUs.

While Zen 4 is aiming to launch in 2022, the Zen 5 architecture is slated for a 2023-2024 launch. It looks like the transition to Zen 5 from Zen 4 would be faster than the transition from Zen 3 to Zen 4. The report states that AMD is expected to detail its vision of the future (likely in the form of new roadmaps) at Computex 2021 which is just a few hours away from now.
