Amazon EC2 M6i Instances

General purpose instances powered by 3rd generation Intel Xeon Scalable processors

Amazon EC2 M6i instances are powered by 3rd generation Intel Xeon Scalable processors and deliver up to 15% better price performance compared to M5 instances. M6i instances feature a 4:1 ratio of memory to vCPU, just like M5 instances and support up to 128 vCPUs per instance, which is 33% more than M5 instances. These instances are SAP-Certified and are ideal for workloads such as backend servers supporting enterprise applications (e.g. Microsoft Exchange and SharePoint, SAP Business Suite, MySQL, Microsoft SQL Server, and PostgreSQL databases), gaming servers, caching fleets, as well as for application development environments.

M6i processor

AWS and Intel have a long-standing relationship dedicated to developing, building, and supporting cloud services that are designed to meet current and future computing requirements for our customers. Please visit the AWS/Intel partner page for more information.


Lower TCO

M6i instances deliver up to 15% better price performance than M5 instances. M6i instances also offer new larger sizes with up to 128 vCPUs and 512 GiB of memory, enabling customers to consolidate workloads on fewer instances.

Flexibility and choice

M6i instances add to the broadest and deepest selection of EC2 instances in the cloud and provide customers 9 different instance sizes that feature varying amount of vCPU, memory, networking, and storage. This enables customers to run a broad range of general purpose workloads.

Maximized resource efficiency

M6i instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor which delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security.


Powered by 3rd Generation Intel Xeon Scalable processors

M6i instances are powered by 3rd generation Intel Xeon Scalable processors (code named Ice Lake) with an all-core turbo frequency of 3.5 GHz, and include support for always-on memory encryption using Intel Total Memory Encryption (TME). M6i instances also support new Intel Advanced Vector Extensions (AVX 512) instructions for faster execution of cryptographic algorithms.

High performance

M6i instances support 40 Gbps bandwidth to Amazon Elastic Block Store (EBS) in the largest size and up to 10 Gbps in the four smallest sizes, which is more than double that of M5 instances. M6i instances also support up to 50 Gbps networking, which is twice that of M5 instances. M6i instances provide up to 20% higher memory bandwidth per vCPU than M5 instances. Customers can also enable Elastic Fabric Adapter (EFA) on the 32xlarge size of M6i.

Built on AWS Nitro System

The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software to deliver high performance, high availability, and high security while also reducing virtualization overhead.
