Announcing new high performance computing Amazon EC2 Hpc8a instances

AWS announces Amazon EC2 Hpc8a instances, the next generation of high performance computing optimized instance, powered by 5th Gen AMD EPYC processors (formerly code named Turin). With a maximum frequency of 4.5GHz, Hpc8a instances deliver up to 40% higher performance and up to 25% better price performance compared to Hpc7a instances, helping customers accelerate compute-intensive workloads while optimizing costs.

Built on the latest sixth-generation AWS Nitro Cards, Hpc8a instances are designed for compute-intensive, latency-sensitive HPC workloads. They are ideal for tightly coupled applications such as computational fluid dynamics (CFD), weather forecasting, explicit finite element analysis (FEA), and multiphysics simulations that require fast inter-node communication and consistent high performance.

Hpc8a instances feature 192 cores, 768 GiB memory and 300 Gbps of Elastic Fabric Adapter (EFA) network bandwidth, enabling fast, low-latency cluster scaling for large-scale HPC workloads. Compared to Hpc7a instances, Hpc8a instances also provide up to 42% higher memory bandwidth, further improving performance for memory-intensive simulations and scientific computing workloads.

Hpc8a instances are available today in US East (Ohio) and Europe (Stockholm). Customers can purchase Hpc8a instances via Savings Plans or On-Demand instances. To get started, sign in to the AWS Management Console. For more information visit the Amazon EC2 Hpc8a instance page or AWS news blog.
