Description
AMD Zen Core Architecture
Improved energy efficiency, higher clock speeds and more cores than ever before.
Setting the Bar for High Performance
AMD’s high-performance x86 Core “Zen 2” architecture enables 3rd Gen Ryzen™ Processors like the AMD Ryzen™ 9 3900X deliver the high single-thread and multi-thread performance for mainstream desktop processors1. For gamers and creators alike, that’s mission-critical performance built to help you win.
Compute Efficiency by Design
The “Zen 2” core is a significant update to the historic “Zen” architecture. Now featuring:
- Up to 15% more instructions-per-cycle2
- 2X L3 cache capacity (up to 32MB)
- 2X floating point throughput (256-bit)
- 2X OpCache capacity (4K)
- 2X Infinity Fabric bandwidth (512-bit)
- New TAGE branch predictor
Zen 2” Microarchitecture Details
“Zen 2” cores are designed to efficiently use available microarchitectural resources for optimal compute performance. Compared to our previous architecture, 2X floating point capabilities and up to 15% higher instructions per cycle enable new performance thresholds.2
Performance and Efficiency for Next-Gen Applications
Cloud computing, enterprise productivity, immersive visual experiences, gaming and streaming all demand increasing computing performance with optimal energy efficiency. From the very beginning, AMD engineers designed the new “Zen 2” core to meet those demands with more core throughput, larger caches, and powerful multi-threading capabilities.
Architecture Highlights
- Available 2-Way SMT
- New 4K OpCache
- Up to 36MB L2+L3 Cache
- 2X Floating Point Throughput
- Precise CPU Boost
- 7nm FinFET Transistors
