https://aws.amazon.com/polly/ In January 2022, https://aws.amazon.com/blogs/aws/new-amazon-ec2-hpc6a-instance-optimized-for-high-performance-computing/ for customers to efficiently run their compute-bound high performance computing (HPC) workloads on AWS with up to 65 percent better price performance over comparable x86-based compute-optimized instances. As their jobs grow more complex, customers have asked for more cores with more compute performance and more memory and network performance to reduce the time to complete jobs.

Hpc7a instances powered by the https://www.amd.com/system/files/documents/4th-gen-epyc-processor-architecture-white-paper.pdf (Genoa) deliver up to 2.5 times better performance compared to Hpc6a instances.

Hpc7a instances feature Double Data Rate 5 (DDR5) memory, which provides 50 percent higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory.

If you are running on Hpc6a, you can use Hpc7a instances and take advantage of the 2 times higher core density, 2.1 times higher effective memory bandwidth, and 3 times higher network bandwidth to lower the time needed to complete jobs compared to Hpc6a instances.
