The AMD Ryzen™ processor has smarter cores

"Zen"" Core Architecture

Setting the Bar for High Performance and Efficiency

AMD’s high-performance x86 Core “Zen” architecture delivers >52% improvement in instructions-per-clock cycle over the previous generation AMD core.1

2nd Gen Ryzen processors offer even more performance, improved with the new “Zen+” architecture delivering the first desktop processor on the advanced 12nm process node.2,3

Compute Efficiency by Design

The “Zen” core is an all-new “clean sheet” x86 processor design that’s inspiring a new generation of high-performance AMD computing products in 2017 and beyond. “Zen” combines the latest thinking in high-throughput and low-power design methodologies to create a balanced and versatile architecture right at home in the desktop, laptop, datacenter and supercomputer.

And now, for 2nd Gen Ryzen desktop processors, the “Zen” architecture has been updated to “Zen+” – the first desktop processor on the advanced 12nm process node - offering increased instructions-per-clock performance.3

Performance and Efficiency for Next-​Gen Applications

Cloud computing, enterprise productivity, immersive visual experiences, gaming and data security open up new frontiers – and demand more computing performance with optimal energy efficiency. From the very beginning, AMD engineers designed the new “Zen” core to meet those demands with a high-performance execution engine, large caches, and powerful multi-threading capabilities.

“Zen” Microarchitecture Details

"Zen” cores are designed to efficiently use available microarchitectural resources for optimal compute performance. Compared to our previous architecture, three-tier cache system and new pre-fetch algorithms enable dramatically higher throughput in the cache and execution engines.

Architecture Highlights

Two threads per core (SMT)4

All-new Micro-op Cache

Up to 20MB Unified Cache

Two AES units for security

High-precision MHz Boost

High efficiency FinFET transistors

AMD AM4 Chipsets

Powered by the AM4 Platform

The AMD AM4 Platform puts effortless compatibility front and center. Our 1331-pin processor socket works with AMD Ryzen™ Desktop Processors and AMD 7th Gen Desktop Processors. The one Socket AM4 motherboard you buy will work with any AM4 processor (some 300-series boards may require a BIOS flash). And with support for the latest I/O standards like USB 3.1 Gen 2, NVMe, or PCI Express® 3.0, it’s easy to build a high-performance system that can grow with your needs.2

Footnotes
  1. Updated Feb 28, 2017: Generational IPC uplift for the “Zen” architecture vs. “Piledriver” architecture is +52% with an estimated SPECint_base2006 score compiled with GCC 4.6 –O2 at a fixed 3.4GHz. Generational IPC uplift for the “Zen” architecture vs. “Excavator” architecture is +64% as measured with Cinebench R15 1T, and also +64% with an estimated SPECint_base2006 score compiled with GCC 4.6 –O2, at a fixed 3.4GHz. System configs: AMD reference motherboard(s), AMD Radeon™ R9 290X GPU, 8GB DDR4-2667 (“Zen”)/8GB DDR3-2133 (“Excavator”)/8GB DDR3-1866 (“Piledriver”), Ubuntu Linux 16.x (SPECint_base2006 estimate) and Windows® 10 x64 RS1 (Cinebench R15). SPECint_base2006 estimates: “Zen” vs. “Piledriver” (31.5 vs. 20.7 | +52%), “Zen” vs. “Excavator” (31.5 vs. 19.2 | +64%). Cinebench R15 1t scores: “Zen” vs. “Piledriver” (139 vs. 79 both at 3.4G | +76%), “Zen” vs. “Excavator” (160 vs. 97.5 both at 4.0G| +64%). GD-108
  2. Testing by AMD Performance labs as of 3/02/2018 on the following system. PC manufacturers may vary configurations yielding different results. Results may vary based on driver versions used. AMD 2nd Gen Ryzen System Config:  AMD Ryzen 7 2700X, ‘Turpan’ reference motherboard, 16GB of dual-channel DDR3-3200, GeForce GTX 1080 Ti Graphics Card, Graphics driver 390.77, and a Samsung 850 PRO 512GB SSD using the Windows 10 RS3 operating system. AMD Ryzen System Config:   AMD Ryzen 7 1700X, 1700, Ryzen 5 1600X, Ryzen 5 1600 X370 Xpower Gaming Titanium motherboard, 16GB of dual-channel DDR3-3200, GeForce GTX 1080 Ti Graphics Card, Graphics driver 390.77, and a Samsung 850 PRO 512GB SSD using the Windows 10 RS3 operating system. Multiprocessing performance represented by Cinebench R15 nT multiprocessing performance. Each processor achieved the following scores: AMD Ryzen 7 2700X, 1837; AMD Ryzen 7 2700, 1577; AMD Ryzen 5 2600X, 1373; AMD Ryzen 5 2600, 1311; AMD Ryzen 7 1800X, 1628; AMD Ryzen 7 1700, 1411; AMD Ryzen 5 1600X, 1250; AMD Ryzen 5 1600, 1153. The Ryzen 7 2700X achieved a score of 1837 (1837/1628= up to 13% faster than the Ryzen 7 1800X).  The Ryzen 7 2700 achieved a score of 1577 (1577/1411=up to 12% faster than the Ryzen 7 1700).  The Ryzen 5 2600X achieved a score of 1373 (1373/1250= up to 10% faster than the Ryzen 5 1600X).  The Ryzen 5 2600 achieved a score of 1311 (1311/1153= up to 14% faster than the Ryzen 5 1600).
