AMD Zen 4 CPU Roadmap: Genoa and Bergamo Details and Intel’s IDM 2.0 Strategy

In July, Intel released a new roadmap outlining five product generations over four years, introducing the IDM 2.0 strategy to accelerate adoption of the Intel 20A process node.

At AMD’s Accelerated Data Center event, CEO Lisa Su unveiled the Zen 4 CPU roadmap, highlighting the 96‑core Genoa and 128‑core Bergamo EPYC processors, both fabricated on TSMC’s 5 nm technology.

AMD claims the 5 nm process delivers double the density and power efficiency of the previous 7 nm node, with a 1.25× performance uplift.

The roadmap includes the fourth‑generation EPYC line: Genoa (96 cores, DDR5, PCIe 5.0, CXL 1.1) slated for 2022, and Bergamo (128 cores, Zen 4c cores optimized for cloud‑native workloads) expected in early 2023. Bergamo shares the same socket as Genoa and supports the same I/O features.

Zen 4c cores are a smaller variant of Zen 4, designed for high‑thread‑density cloud workloads, potentially with reduced cache hierarchy to increase core count.

AMD also disclosed cache details: L1 remains 32 KB (8‑way), L2 doubles from 512 KB to 1 MB (8‑way), while L3 size was not announced.

Intel’s parallel IDM 2.0 roadmap aims to bring its own 5‑generation product iterations within the same four‑year window, intensifying the competition between the two chipmakers.
