Talking Zen 6 with Mike Clark at AMD In-Depth
Summary
This AMD In-Depth interview with Mike Clark covers Zen 6 and the evolution from Zen 5/6c, detailing a two-core family approach where the dense performance core enables higher IPC with full L3 (128MB total for 32 cores) and a high-frequency design. It discusses architectural changes such as a larger vector scheduler, expanded front-end decode, reduced integer multiply units, added VNNI for AI workloads, and memory/bandwidth tuning, including LPDDR5X considerations for EPYC. The conversation highlights design trade-offs to keep features usable across Zen 6 and Zen 6c while boosting performance and efficiency.
