AMD next-gen Zen architectures get their codenames

AMD is gearing up for the launch of its Zen5 series, expected to make its debut in 2024, with a likelihood of initial products hitting the market in the first half of the year. Officially, the Zen5 architecture will consist of three sub-architectures: Zen5, Zen5 with 3D V-Cache, and a dense version known as Zen5c. These architectures are anticipated to leverage both 4nm and 3nm process technologies.

Information gleaned from LinkedIn suggests that the codename for the AMD Zen5c architecture may have been unveiled. The Prometheus, the supposed codename for Zen5c core design, is expected to join forces with Nirvana (Zen5) for AMD’s next-generation products. Considering AMD’s recent announcement of Phoenix2, there is an expectation that at some point one of future product may incorporate both core architectures as well.

It’s important to highlight that the previously mentioned codename “Nirvana” for the Zen5 core design diverges from the established pattern of drawing inspiration from Greek and Roman mythology. In contrast, Zen4 adopted the name Dionysus, in line with the mythology where Zen4c Dionysus is the child of Persephone. It’s worth noting that Prometheus, on the other hand, is an ancient Greek god associated with fire.

  • Zen 4c (5nm) – Dionysus
  • Zen 5 (3/4nm?) – Nirvana
  • Zen 5c (3/4nm?) – Prometheus?
  • Zen 6 (2nm) – Morpheus

There are rumors that AMD is currently considering Samsung as a potential foundry for its 4LPP process. The profile of an AMD worker lends credence to these rumors, hinting at an ongoing collaboration with Samsung on utilizing their 4nm node. The two companies have become closer because they worked together to add RDNA technology to the Exynos SoC series. In the context of AMD Zen5 nodes, reports suggest a dual approach, involving both TSMC’s 4nm and 3nm nodes. This implies that the Samsung 4nm process may find application in a different aspect of AMD’s operations.

AMD Zen5 architecture will be used by many of the future products, including desktop Ryzen “Granite Rapids”, mobile “Strix Point and Halo” and next-gen EPYC 9005 “Turin” series.
