“Zen 4”: The AMD 5nm 5.7GHz x86-64 Microprocessor Core

📋 论文概要

本文介绍了AMD的Zen 4 x86-64微处理器核心，采用5nm FinFET工艺制造，通过与台积电的紧密合作优化了工艺和缩放性能。该核心相比上一代Zen 3在7nm工艺上实现了显著的性能提升。

💡 主要创新点

• 采用5nm FinFET工艺，与台积电合作优化工艺缩放，实现更高性能和能效
• 微架构的改进以支持更高频率（5.7GHz）和更强计算能力
• 通过工艺-设计协同优化（DTCO）提升晶体管密度和功耗效率

Close collaboration between the design team and TSMC enabled an optimized process and excellent process scaling relative to the 7nm process used for “Zen 3” [1]. The 55mm2 core complex (CCX), shown in Fig. 2.1.1, contains 6.5B transistors across eight cores, similar to the 8 core CCX in the previous generation. Each core includes a 1MB private L2 cache, double the previous generation, and the eight cores share a 32MB L3 cache. The design also delivers a process-neutral performance
