AMD has been less forthcoming about the specifics of its CPU roadmap than Intel lately. Chipzilla has laid out explicitly which chips will theoretically come out when and which processes and technologies they’ll be using. Whether Intel hits those targets is another matter entirely. AMD, however, has simply shared that while Zen 4 is made on TSMC’s 5nm process, its upcoming CPU architecture will use an “advanced node.” Now we know what that node is and the one after it, thanks to an AMD employee who shared the info in his LinkedIn profile.
A person named Md Zaheer works as a Senior Silicon Design Engineer at AMD. They’ve been there for over three years and are involved in “Core Power management verification at both IP level and SOC level,” according to the LinkedIn bio. This person recently spilled the beans on the specifics of their duties, much to the company’s chagrin, as the biography has now been cleansed. However, via TechSpot, a Twitter account for Maraux David captured screenshots for all of our benefit, then deleted them.

It was assumed that since AMD is using TSMC 5nm for Zen 4, it would use its 3nm node for Zen 5. The engineer’s post seems to confirm this, along with its code name: Nirvana. We don’t know that AMD will use TSMC, as Samsung also has an available 3nm node, but that would be a shocking turn of events given AMD’s history as a TSMC customer. Even more intriguing is Zaheer wrote Zen 6 would be built on a 2nm process and codenamed Morpheus.

If we again assume AMD sticks with TSMC, it’ll be built on the company’s first post-FinFET process using nanosheet gate-all-around (GAA) transistors. That process is supposed to go into production in 2025, which is the same time AMD said it will end support for its current AM5 socket. This implies Zen 5 would use the same AM5 socket as Zen 4 before transitioning to a new design for Zen 6. If that happens, it will likely upset some AMD fans, as two generations of CPUs is less than what AM4 enjoyed and what Intel has been doing for a while now.
Intel might beat TSMC to the post-FinFET punch if it executes its roadmap correctly. But as always, it remains to be seen if that will happen. It’s theoretically targeting late 2024 to begin its 2nm production with its 20A process for Arrow Lake. However, it has to launch Meteor Lake first, which is its first tile-based design. That’s due later this year on Intel 4 (7nm) and is a crucial component in the company’s journey from monolithic designs to a more flexible tile-based approach that it will use for the years to come.
