      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.

      Workload Profiles

      7.4Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
