[AMD EPYC] A new generation of CPU for cloud/server

Updated: Apr 29, 2022

Hello there!

This is Jon from Beyond GTA, and this blog will briefly describe features of new CPU generation "AMD EPYC" in cloud usage such as AWS and GCP

AMD EPYC Overview

● World's highest performance x86 CPU

● Performance improvement with the latest “Zen3” core

● AMD EPYC ™ 7003 PROCESSORS (development code name “MILAN”)

● Compatibility to use Rome platform with drop-in (BIOS update required)

● Expansion of security functions

● Support for 4ch / 6ch / 8ch channel memory

● For memory performance (up to 32MB per Core x86 maximum capacity L3 cache)

Features of each cloud

​Cloud name
