The “Zen 2” processor is designed to meet the needs of diverse markets spanning server, desktop, mobile, and workstation. The core delivers significant performance and energy-efficiency improvements over “Zen” by microarchitectural changes including a new TAGE branch predictor, a double-size op cache, and a double-width floating-point unit. Building upon the core design, a modular chiplet approach provides flexibility and scalability up to 64 cores per socket with a total of 256 MB of L3 cache.
