The Zen Core Architecture
Maximum Compute Efficiency
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.
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 maximum 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.
Two threads per core (SMT) 1
All-new Micro-op Cache
Up to 20MB Unified Cache
Two AES units for security
High-precision MHz Boost
High efficiency FinFET transistors
Powered by the AM4 Platform
The new AMD AM4 Platform puts effortless compatibility front and center. Our new 1331-pin processor socket works with the 7th Gen AMD APU, AMD Ryzen CPU, and the upcoming “Raven Ridge” APU. The one Socket AM4 motherboard you buy will work with any AM4 processor! 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
- 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
- Not all AMD Ryzen™ or “Raven Ridge” products are enabled with SMT.
