Server Description
A dedicated high-performance computing instance combining AMD EPYC processors with massive DDR5 memory bandwidth and high-speed networking.
The Amazon Web Services hpc7a.12xlarge is a dedicated high-performance computing instance featuring 24 physical cores and 24 vCPUs powered by AMD EPYC 9R14 processors running at 3.7 GHz. Built on the AWS Nitro hypervisor, it provides 768.0 GB of DDR5 memory at 5 GHz, yielding 32.0 GB of RAM per core, but lacks local storage and GPU accelerators. It features a 150 Gbps baseline network bandwidth. In benchmarks, the instance delivers top-tier performance in large-block memory bandwidth and strong results in multi-core CPU tests, though database and web serving operations remain average. This profile makes it highly efficient for memory-bound computational tasks, scientific simulations, and multi-threaded processing, offering a specialized balance of high memory capacity and dedicated compute resources without local storage overhead.
