Server Description
A high-density compute server featuring ninety-six virtual cores and dedicated AMD EPYC processing for intensive multi-threaded workloads.
Amazon Web Services c6a.24xlarge is an x86_64 compute-optimized server featuring an AMD EPYC 7R13 processor with 96 vCPUs, 48 physical cores, and a 3.6 GHz clock speed. It is equipped with 192.0 GB of DDR4 memory, providing a 2.0 GB per core ratio, and operates on the Nitro hypervisor with a 38 Gbps baseline network bandwidth. The server lacks local storage and GPU accelerators. Benchmarks show top 10% performance in multi-core stress testing and CPU encryption, alongside top 25% performance in database operations and Redis SET transactions. Large-block memory bandwidth and web serving throughput remain in the middle 50%. This profile makes the instance highly efficient for compute-intensive workloads such as software compilation, cryptographic processing, and multi-threaded batch jobs that do not require local NVMe storage.
