Consumers are thrilled with AMD’s new award-winning line-up of “Zen”-based products, like Ryzen™ processors, Ryzen™ Threadripper™ CPUs and more. Now it’s time for AMD to expand what’s available for the datacenter. It’s time for EPYC.

AMD’s latest development in “Zen”-based server architecture, EPYC™ processors, are changing how the industry defines the datacenter. Optimal balance of performance and power highlight AMD’s much anticipated re-entry into the server market.  In the past decade, the datacenter ecosystem has transitioned from single-focus systems to virtualized, on-premise solutions to the cloud, and from proprietary applications to open source software. EPYC processors are engineered from the ground up based on the datacenter of today, and to empower the datacenter of the future.


EPYC Processors: By the Numbers

          • 32, 24, 16, and 8 cores options

          • 128 PCIe® Gen 3 Lanes in a single CPU (the largest I/O capacity1)

          • 8 Memory Channels per CPU

          • 2TB RAM per socket

EPYC is the server CPU that customers crave: industry-leading server processor core counts, memory capacity, memory-bandwidth, and I/O capacity.1,2,3,4 Offering the first no-compromise single-socket and ground-breaking dual-socket solutions, it is designed for workloads of today and tomorrow.

EPYC processors challenge the performance of many current dual-socket configurations in a single-socket solution, which can reduce overall cost, maintenance, and help improve power/heat efficiency. While AMD offers leading edge dual-socket solutions, customers will find a single EPYC processor configuration can satisfy many of their current dual-socket workloads.5

An EPYC™ 7551p processor-based one-socket server draws 20% less power versus an Intel Xeon 5118 processor based dual-socket server, and achieves an estimated overall 31% better performance per dollar.6, 7 When the workload demands a dual-socket solution, a dual EPYC 7601 processor-based server delivers 14% more cores, 33% more bandwidth and 2.3x the performance per dollar of a comparable Intel Xeon Platinum 8180M dual-socket server in SPECfp®_rate 2006 scores.1,2,8 The numbers speak for themselves. EPYC processors are designed with your customers’ current workloads in mind – and the demands of the future.

It isn’t just about more cores, I/O, and memory – EPYC is architected with security at its core.

Security Features Beyond the Status Quo 

Security is integral to the core EPYC design and provides a host of technologies that help ensure customers can depend on a powerful and secure experience.

Customers boot from a Secure Root-of-Trust, a chip-level security technology designed to eliminate any potential breaches at the heart of the system.

Secure Memory Encryption (SME) is an X86 security technology extension exclusive to AMD products that helps protect system memory from attempted breaches. EPYC processors also deliver Secure Encrypted Virtualization (SEV), giving each Virtual Machine its own encryption key to help prevent an attack into and between Virtual Machines.

An EPYC Ecosystem 

While EPYC processors clearly disrupt the status quo of the industry, it easily fits into existing datacenter environments through a common set of X86 instructions with Intel’s Xeon products. Additionally, existing Xeon based Virtual Machines can be migrated to EPYC processor Virtual Machines, and vice versa.

EPYC processors are tested, certified and ready for use on Windows® Server and major Linux® distributions. EPYC processors have been extensively tested and validated with major component manufacturers for memory, storage, network and other hardware.

EPYC Has Arrived

No need to delay an EPYC processor-based server implementation. An extensive ecosystem including ASUS, Gigabyte, Supermicro and Tyan are ready now. For a list of EPYC solution-ready partners, look here.
