• AWS News Blog Amazon EC2 Hpc8a Instances powered by 5th Gen AMD EPYC processors are now available | Today, we’re announcing the general availability of Amazon Elastic Compute Cloud (Amazon EC2) Hpc8a instances, a new high performance computing (HPC) optimized instance type powered by latest 5th Generation AMD EPYC processors with a maximum frequency of up to 4.5 GHz. • These instances are ideal for compute-intensive tightly coupled HPC workloads, including computational fluid dynamics, simulations for faster design iterations, high-resolution weather modeling within tight operational windows, and complex crash simulations that require rapid time-to-results. • The new Hpc8a instances deliver up to 40% higher performance, 42% greater memory bandwidth, and up to 25% better price-performance compared to previous generation Hpc7a instances. • Customers benefit from the high core density, memory bandwidth, and low-latency networking that helped them scale efficiently and reduce job completion times for their compute-intensive simulation workloads. • Hpc8a instances Hpc8a instances are available with 192 cores, 768 GiB memory, and 300 Gbps Elastic Fabric Adapter (EFA) networking to run applications requiring high levels of inter node communications at scale. • Instance Name | Physical Cores | Memory (Gib) | EFA Network Bandwidth (Gbps) | Network Bandwidth (Gbps) | Attached Storage | Hpc8a.96xlarge | 192 | 768 | Up to 300 | 75 | EBS Only | Hpc8a instances are available in a single 96xlarge siz

Article Summaries:

  • Amazon announced the general availability of its new EC2 Hpc8a instance type, which is powered by 5th‑generation AMD EPYC processors that can reach up to 4.5 GHz. The single 96‑core, 768 GiB memory configuration offers up to 40 % higher compute performance, 42 % greater memory bandwidth, and 25 % better price‑performance versus the previous Hpc7a generation. Designed for tightly coupled high‑performance computing workloads-such as CFD, weather modeling, and crash simulations-the instances feature 300 Gbps Elastic Fabric Adapter networking and use Nitro cards for enhanced security and performance. Hpc8a is available in the US East (Ohio) and Europe (Stockholm) regions as On‑Demand or Savings Plan options.
