Server Description
A dedicated 32-core AMD EPYC compute instance with DDR5 memory, optimized for high-throughput processing and software compilation workloads.
Amazon Web Services c7a.8xlarge is a compute-optimized instance featuring 32 dedicated physical cores and 32 vCPUs powered by an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the Nitro hypervisor, the server includes 64.0 GB of DDR5 memory at 5 GHz, yielding a 2.0 GB per core ratio. It lacks local storage and GPU accelerators but provides a baseline network bandwidth of 12 Gbps. Performance benchmarks place the instance in the top 25% for single-core and multi-core CPU execution, software compilation, and database operations. It also demonstrates top-tier efficiency in prompt processing for small language models. The c7a.8xlarge is optimized for compute-heavy workloads such as ray tracing, software development, and database tasks, offering a balanced hardware profile for applications that require high-frequency processing without massive memory footprints or local storage.
