https://aws.amazon.com/polly/ We launched the memory optimized https://aws.amazon.com/blogs/aws/new-amazon-ec2-r6a-instances-powered-by-3rd-gen-amd-epyc-processors-for-memory-intensive-workloads/ in July 2022 powered by 3rd Gen AMD EPYC (Milan) processors, running at frequencies up to 3.6 GHz. Today, we’re announcing the general availability of new memory optimized https://aws.amazon.com/ec2/instance-types/r7a/ powered by 4th Gen AMD EPYC (Genoa) processors with a maximum frequency of 3.7 GHz, which offer up to 50 percent higher performance compared to the previous generation instances.

Moreover, these instances support always-on memory encryption using AMD secure memory encryption (SME).

Additionally, with R7a instances you can attach up to 128 EBS volumes to an instance compared to up to 28 EBS volume attachments with R6a instances. R7a instances support AES-256 compared to AES-128 in R6a instances for enhanced security.
