Higher speeds. More memory. Wider bandwidth. You must push every lever, squeeze every ounce, and leave nothing on the table. AMD’s 3rd Gen Ryzen™ processor was designed to break expectations and set a new standard for high-performance processors.

The 3rd Gen AMD Ryzen™ processor is built using the world’s most advanced manufacturing technology to deliver winning performance while keeping your system astonishingly cool & quiet.

3rd Gen Ryzen processors feature support for the world’s first PCIe 4.0 ready platform2, enabling the most advanced motherboards, graphics, and storage technologies available.

AMD GameCache
More Memory On-Chip to Accelerate Gaming
Up to twice the cache of previous generations, GameCache is designed to reduce memory latency for higher frame rates in top titles.

Precision Boost 2
Boost performance when you need it. Precision Boost 2 automatically raises the processor frequencies for supercharged performance when you need it most.

One Click Overclocking
Making Precision Boost 2 even better, Precision Boost Overdrive3 uses your AMD X400 series or X570-based motherboard’s4 robust design to boost clock speeds higher and longer, and lets you overclock5 at the touch of a button.

AMD StoreMI Technology
Software that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive.

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 to deliver the highest single-thread and multi-thread performance of any mainstream desktop processor. 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

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.

“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.

AMD Ryzen Master
Every AMD Ryzen processor is multiplier-unlocked from the factory, so you can personalize performance to your taste. AMD provides the AMD Ryzen Master utility to access this powerful advantage. Ryzen Master also now includes Dynamic Local Mode, an exciting new feature specifically for AMD Ryzen™ Threadripper™ WX Series processors that can automatically improve performance in select applications.
