AMD Zen 6 processors are being built on 2nm process node

The codename and process node for AMD’s distant Zen 6 processors have been revealed by a purported AMD engineer’s LinkedIn profile. The next microarchitecture to be released is Zen 5, which is expected to hit the market in 2024, so there’s still a long way to go before we see any signs of Zen 6 processors.

Md Zaheer, who appears to be a senior silicon design engineer at AMD who has worked on the power management aspect of Zen 4, Zen 5, and Zen 6 processors, provided the new information.

The individual has since changed the names of the AMD projects on which he has worked, but Twitter user Maraux David captured a screenshot of the original description prior to the changes. It’s not a huge blunder, given that AMD has already revealed some details about Zen 5. It does, however, provide some information on Zen 6 processors.

There are no official AMD roadmaps for Zen 6 processors, as the chipmaker has only shared plans for up to Zen 5.

According to AMD’s most recent roadmap, which dates back to June 2022, Zen 5 will be released in 2024. As a result, the Zen 6 is unlikely to hit the retail market until 2025, if at all.

The internal codename for AMD’s Zen 6 cores is Morpheus, according to Zaheer, who began working on Zen 6 processors in early 2023. However, the author did not reveal the CCD codename. Zen 6 chips are said to be manufactured on a 2nm process. However, it is unclear whether AMD will continue to use TSMC for CCD production or switch to Samsung.

The silicon engineer appears to have worked on Zen 5 from January 2021 to December 2022, indicating that Zen 5 is on track for a 2024 release according to AMD’s roadmap. The Zen 5 processors’ commercial name is unknown, but AMD refers to the mainstream chips as Granite Ridge. We now know that Zen 5 cores are internally known as Nirvana, whereas the CCD is known as Eldora.

AMD previously stated that Zen 5 would be built on a “advanced node,” which we speculated could be 4nm or 3nm. According to Zaheer’s previous remarks, Zen 5 will include a 3nm furnace. It’s worth noting that he was a member of the development team for server chips, most likely EPYC. There have been rumours that the Zen 5 will be available in 4nm and 3nm variants.

AMD will fully utilise the Zen 5 microarchitecture. Granite Ridge for the mainstream market and EPYC Turin for servers will be the first to see Zen 5. AMD will also release Zen 5c core chips for Zen 5, which are theoretically similar to Intel’s E-cores found on mainstream 13th Generation Raptor Lake processors.
