AMD Zen 6: A Sneak Peek

1. Microarchitecture Overview

  • Zen is the codename for a family of computer processor microarchitectures from AMD.
  • It was first launched in February 2017 with the debut of the first-generation Ryzen CPUs.
  • Zen architecture powers various AMD products, including Ryzen (desktop and mobile), Ryzen Threadripper (workstation and high-end desktop), and Epyc (server) processors.

2. Generations of Zen: A Quick Recap

  • First Generation (Zen):
    • Launched with the Ryzen 1000 series CPUs (codenamed Summit Ridge) in early 2017.
    • Utilized GlobalFoundries’ 14 nm manufacturing process.
  • First Generation Refresh (Zen+):
    • Released in April 2018, powering Ryzen 2000 processors (Ryzen 2000 series) and Threadripper 2000 processors.
    • Used GlobalFoundries’ 12 nm process.
  • Second Generation (Zen 2):
    • Ryzen 3000 series CPUs arrived in July 2019.
    • Epyc server CPUs (codename “Rome”) followed in August 2019.
    • Zen 2 introduced chiplet-based architecture, utilizing TSMC’s 7 nm process node.
    • Core chiplets were attached to different uncore silicon (IO dies) in a hub-and-spoke topology.

3. Zen 6: The Exciting Future

  • Targeted IPC Gains:
    • AMD aims for over 10% IPC gains compared to Zen 5.
  • Advanced Silicon Process:
    • Zen 6 is expected to use 3 nm or 2 nm silicon.
    • AMD will fully embrace die stacking, significantly reducing processor latency.
  • Hybrid Core Design:
    • Rumored to offer over 200 cores (conservative estimate) with whispers of up to 384 cores per socket.
    • Could stack CPU cores on top of an I/O die.

4. Conclusion

  • While Zen 6 doesn’t revolutionize the architecture landscape, its focus on performance gains, advanced silicon, and hybrid core design makes it an exciting prospect for future AMD processors.
