Server Description
A dedicated 96-core high-performance computing platform with high-speed DDR5 memory and 150 Gbps networking for intensive parallel processing workloads.
Amazon Web Services hpc7a.48xlarge is a high-performance computing instance featuring 96 dedicated physical cores and 96 vCPUs powered by an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the Nitro hypervisor, it includes 768.0 GB of high-speed 5 GHz DDR5 memory, translating to 8.0 GB per core, and delivers a baseline network bandwidth of 150 Gbps. The instance lacks local storage and GPU accelerators, representing a tradeoff for storage-heavy or graphics-intensive tasks. However, it excels in compute-heavy benchmarks, achieving top-tier multi-core performance, exceptional memory bandwidth, and highly efficient multi-threaded processing. It is optimized for demanding workloads such as high-performance computing, complex scientific simulations, software compilation, and CPU-based large language model inference.
