SOLUTION BRIEF

Executive Summary

Supermicro has closely partnered with AMD since

becoming one of the first server vendors to bring 1st

Gen AMD EPYC™ processors with “Zen”

microarchitecture to market in our H11 platforms in

2017. In 2019, Supermicro launched its first family of

H12 generation AMD processor-powered Supermicro

A+ servers with 2nd Gen AMD EPYC processors to

deliver a new level of integration and superior

performance for modern datacenters. Today, the

new 3rd Gen AMD EPYC Processors in the new

Supermicro A+ servers deliver up to 19% more

instructions per clock than the previous generation

Gen AMD EPYC processors have up to 64 “Zen 3”

cores per CPU, introduce new levels of per-core cache

memory, and offer PCIe® 4.0 connectivity bandwidth.

They also include AMD Infinity Guard

, which offers

Secure Encrypted Virtualization-Secure Nested

Paging (SEV-SNP) to help enhance security in

SUPERMICRO

Supermicro (Nasdaq: SMCI), the leading innovator in high-

performance, high-efficiency server, and storage technology

is a premier global provider of advanced server Building Block

Solutions® for Enterprise Data Center, Cloud Computing,

Artificial Intelligence, and Edge Computing Systems.

Supermicro is committed to protecting the environment

through its “We Keep IT Green®” initiative and provides

customers with the most energy-efficient, environmentally

friendly solutions available on the market.

virtualized environments. SEV-SNP expands on the SEV features found in earlier EPYC processors by

adding memory integrity capabilities that can help prevent hypervisor-based attacks by creating an

isolated execution environment for each virtual machine.

AMD EPYC 7003 Series Processors Deliver Flexibility, Performance, and Security Features

Overview

AMD EPYC 7003 Series Processors retain the proven Multi-Chip Module (MCM) Chiplet Architecture of

prior successful AMD EPYC server-class processors with further improvements and upgraded “Zen 3”

compute cores.

A. “Zen 3” Core Microarchitectural Overview

AMD EPYC 7003 Series Processors are built with new 7nm “Zen

3” compute cores that provide an Instructions per Cycle (IPC)

uplift over previous “Zen” generations. Each core supports

Simultaneous Multi-threading (SMT) that allows running two

simultaneous threads per core when enabled. Every core

includes both an optimized 32 KB L1 cache and a private 512 KB

Unified (Instruction/Data) L2 cache.

B. Core Complex (CCX) and Core Complex Die (CCD)

Up to eight “Zen 3” compute units share an L3 cache of up to

32 MB in a grouping referred to as a Core Complex (CCX).

Enabling SMT on a core means that a CCX may support up to

16 concurrent hardware threads, up to 4 MB of L2 cache, and

up to 32 MB L3 cache, which is shareable across all cores within the CCX. AMD EPYC 7003 Series

Processors contain a single CCX called a Core Complex Die (CCD) on a single die. See Figure 2.

C. I/O Die (Infinity Fabric™ technology)

Each CCD connects to memory, I/O, and each other through

the I/O Die (IOD) via a dedicated high-speed or Global

Memory Interconnect (GMI) link. The IOD also contains

memory channels, PCIe Gen4 lanes, and Infinity Fabric™
