Amazon RDS for PostgreSQL now supports M6i and R6i instances with new instance sizes up to 128 vCPUs and 1,024 GiB RAM
Amazon Relational Database Service (Amazon RDS) for PostgreSQL, version 11 and higher, now supports M6i and R6i instances. M6i instances are the 6th generation of Amazon EC2 x86-based General Purpose compute instances, designed to provide a balance of compute, memory, storage, and network resources. R6i instances are the 6th generation of Amazon EC2 memory optimized instances, designed for memory-intensive workloads. Both M6i and R6i 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.

Both M6i and R6i 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.
M6i and R6i instances are powered by 3rd generation Intel Xeon Scalable processors with an all-core turbo frequency of 3.5 GHz, delivering up to 20% better transaction throughput over equivalent M5 and R5 instances. To meet customer demands for increased scalability, M6i and R6i instances provide a new instance size of 32xlarge with 128 vCPUs and 33% more memory than the largest M5 and R5 instances. M6i.32xlarge has 512 GiB of memory and R6i.32xlarge has 1,024 GiB of memory. They also provide up to 20% higher memory bandwidth per vCPU compared to the previous 5th generation instances. These instances give customers up to 50 Gbps of networking speed and 40 Gbps of bandwidth to the Amazon Elastic Block Store (Amazon EBS), 2x that of M5 and R5 instances.
M6i instances for Amazon RDS for PostgreSQL are available today in US East (N. Virginia), US East (Ohio), US West (Oregon), US West (N. California), Europe (Ireland), Europe (Frankfurt), Asia Pacific (Tokyo), Asia Pacific (Singapore) regions. R6i for Amazon RDS for PostgreSQL are available today in US East (N.
