Why Amazon EC2 Hpc7a Instances?
Amazon Elastic Compute Cloud (Amazon EC2) Hpc7a instances, powered by 4th Gen AMD EPYC processors, deliver up to 2.5x better performance compared to Amazon EC2 Hpc6a instances. Hpc7a instances feature 2x higher core density (up to 192 cores), 2.1x higher memory bandwidth throughput, 2x memory (768 GB), and 3x higher network bandwidth compared to Hpc6a instances. These instances offer 300 Gbps of Elastic Fabric Adapter (EFA) network bandwidth, powered by the AWS Nitro System, for fast and low-latency internode communications. Hpc7a instances feature Double Data Rate 5 (DDR5) memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory. These instances are ideal for compute-intensive, latency-sensitive HPC workloads, helping you scale more efficiently on fewer nodes when compared to Hpc6a instances.
Hpc7a instances are designed to run your tightly coupled HPC workloads such as computational fluid dynamics (CFD), weather forecasting, and multiphysics simulations with better performance.
