01 — Architecture

Zen 4 on
TSMC 5nm

Built on TSMC's cutting-edge 5nm FinFET process, the Zen 4 architecture delivers a massive leap in instructions-per-clock (IPC) and energy efficiency over its predecessor. Two compute chiplets (CCDs) house eight cores each, connected via AMD's Infinity Fabric to a dedicated I/O die.
