Overview

The High Performance "Zen 3" Architecture
Debuting in AMD Ryzen™ 5000 Series desktop processors, the "Zen 3" architecture is a ground-up redesign of the legendary "Zen” family. Equipped with end-to-end design enhancements, "Zen 3" embodies AMD’s relentless focus on single-core performance, energy efficiency, and reduced latencies. It’s at the core of the best gaming processors in the world1.

Features
Total Redesign
The "Zen 3" architecture represents the most comprehensive design overhaul of the "Zen" era. Over 20 major changes include: wider and more flexible execution resources; significantly more load/store bandwidth to feed execution; and a streamlined front-end to get more threads in flight—and do it faster.

Higher Instructions Per Clock (IPC)
The "Zen 3" architecture can extract an average of 19% additional performance from every MHz of frequency relative to the previous generation2. This a historically large generational improvement in IPC, and a major player in the architecture’s ability to deliver unmatched single-core performance1.

Lower Latency
The "Zen 3" architecture transitions to a new "unified complex" design that brings 8 cores and 32MB of L3 cache into a single group of resources. This dramatically reduces core-to-core and core-to-cache latencies by making every element of the die a next-door neighbor with minimal communication time. Latency-sensitive tasks like PC gaming especially benefit from this change, as tasks now have direct access to twice as much L3 cache versus "Zen 2."

King of the Hill
The combination of higher IPC and the unified 8-core complex are a potent combination for PC games. Customers upgrading from the AMD Ryzen™ 3000 Series to the 5000 Series can expect an average of 26% better gaming performance at 1080p3. But that’s not all: processors with "Zen 3," like the AMD Ryzen™ 9 5900X, are the best in the world for PC gaming4.

Incredible Efficiency
Impressively, the performance gains of the "Zen 3" architecture can be delivered with no increase to power consumption or TDP. The combination of a state-of-the-art architecture and industry-leading 7nm process give the AMD Ryzen™ 5000 Series a +24% generational improvement in energy efficiency5, and a stunning 2.8X lead over competing architectures6.
