2.1 Zen 2: The AMD 7nm Energy-Efficient High-Performance x86-64 Microprocessor Core

摘要

Codenamed “Zen 2”, the AMD next-generation, high-efficiency core is an x86-64 design, fabricated in an energy-efficient TSMC 7nm FinFET process. Similar to AMD's prior-generation core, codenamed “Zen” [1], the Core Complex Unit (CCX) with 4 cores in this version (Fig. 2.1.1) is used across a wide array of client, semi-custom, embedded, and server market segments. A 475M-transistor core slice is 7.83mm² with a 0.5MB L2 cache and 4MB of shared L3 cache. The design uses new custom circuits and memory design techniques to achieve the specified performance and power.
