In January 2022, we launched Amazon EC2 Hpc6a instances 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. Additionally, as customers look to bring more of their HPC workloads to EC2, they have asked how we can make it easier to distribute processes to make the best use of memory and network bandwidth, to align with their workload requirements.

Today, we are announcing the general availability of Amazon EC2 Hpc7a instances, the next generation of instance types that are purpose-built for tightly coupled HPC workloads. Hpc7a instances powered by the 4th Gen AMD EPYC processors (Genoa) deliver up to 2.5 times better performance compared to Hpc6a instances. These instances offer 300 Gbps Elastic Fabric Adapter (EFA) bandwidth powered by the AWS Nitro System, for fast and low-latency internode communications.
