      Server Description

      A high-density compute platform featuring dedicated AMD EPYC processors and DDR5 memory for intensive multi-core processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7a.48xlarge is a compute-optimized server featuring 192 dedicated physical cores on an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the Nitro hypervisor, it includes 384.0 GB of DDR5 memory at 5 GHz, yielding a 1:2 vCPU-to-RAM ratio. The instance lacks local storage and GPU accelerators but provides a baseline network bandwidth of 50 Gbps. Benchmark data places this server in the top 10% for multi-core CPU performance, memory bandwidth, and static web serving throughput. It also ranks in the top 25% for single-core execution and database operations. Given its high compute density and lack of local storage, the c7a.48xlarge is optimized for compute-bound workloads such as software compilation, cryptographic processing, high-performance computing, and static web serving.
