Introduction

THE CHANGING DEMANDS OF THE DATACENTER
Datacenters have rapidly evolved, with software innovation greatly surpassing the ability of hardware technology to efficiently support it. The Internet of Things, the Cloud, and an ever increasing mobile workforce have transformed datacenters of all sizes to become service providers, providing intelligible data on demand in a secure manner.
Over the past decade, there have been major advances within the software ecosystem, while the x86 server CPU has seen only incremental and comparatively nominal improvements, leaving the modern datacenter constrained and starved for innovation. This new era of computing demands a new breed of processor, one with the power to efficiently support the workloads of today’s software-defined datacenter while providing protection from the silicon level up against sophisticated threats.
To achieve optimized performance for today’s datacenter applications, a processor that delivers more performance, flexibility, and security through a better balance of resources is essential. AMD offers the innovation required for the cloud-era datacenter with AMD EPYC—a system on chip (SoC) that is designed from the ground up to deliver real innovation to efficiently support the needs of existing and future datacenters.

POWERING THE DATACENTER
The modern datacenter needs more cores, more memory, more I/O, and more security. AMD EPYC powers the datacenter with 32 cores, 64 threads, 8 memory channels with up to 2 TB of memory per socket, and 128 PCIe-3 lanes coupled with the industry’s first hardware-embedded x86 server security solution. With servers built on EPYC technology, cloud environments can drive greater scale and performance, virtualized datacenters can further increase consolidation ratios while delivering better performing virtual machines and Big Data, and analytics environments can collect and analyze larger data sets much faster. High performance applications in research labs can solve complex problem sets in a significantly accelerated manner. EPYC, with all the critical compute, memory, I/O, and security resources brought together in the SoC with the right ratios, delivers industry-leading performance and enables lower TCO.

OPTIMIZING PERFORMANCE
AMD EPYC provides breakthrough processing power balanced with the industry-leading memory and I/O capacity needed to substantially eliminate performance bottlenecks. With the flexibility to choose from 8 to 32 cores, EPYC enables you to deploy the right hardware platforms to meet your workload needs from virtualized infrastructure to large-scale big-data and analytics platforms and legacy line-of-business applications. You can rightsize your infrastructure using EPYC with fewer cores without sacrificing memory capacity or I/O. EPYC provides the memory capacity and bandwidth to processor cores to efficiently run memory-intensive workloads. With EPYC you can leverage industry-leading I/O bandwidth that matches the capability of the CPU cores to move data to and from the network while supporting I/O-intensive workloads.
EPYC, with a balanced set of resources, offers you an unprecedented opportunity to rightsize your datacenter infrastructure for enhanced performance and cost efficiency.
