The new Amazon EC2 Hpc8a instances are powered by AMD's 5th Gen EPYC processors running up to 4.5GHz, delivering up to 40% better performance and 25% improved price-performance than prior Hpc7a models. Featuring 192 cores, 768 GiB RAM, and 300 Gbps Elastic Fabric Adapter networking, these instances suit tightly coupled HPC simulations like CFD, FEA, and multiphysics tasks requiring low-latency inter-node communication.

Built on sixth-generation AWS Nitro cards, Hpc8a instances also offer up to 42% higher memory bandwidth, enhancing scientific and memory-intensive workloads. Initially available in US East (Ohio) and Europe (Stockholm) regions, these instances can be procured on-demand or via Savings Plans, enabling scalable HPC cluster deployments.
