      Server Description

      An entry-level, compute-focused instance with dedicated AMD EPYC processing and a balanced 1:2 vCPU-to-RAM ratio for lightweight workloads.

      Compute Optimized

      Amazon Web Services c5a.large is a compute-optimized instance featuring an AMD EPYC 7R32 processor with 2 vCPUs and 4.0 GB of DDR4 memory. Operating on the Nitro hypervisor, it provides a dedicated CPU allocation at 3.3 GHz but lacks local storage and GPU acceleration. Performance benchmarks show a clear division: single-threaded tasks like gzip compression and Geekbench single-core scores perform at an average level, while multi-core operations, memory bandwidth, and database tasks fall into the bottom 10% to 25% of tested configurations. With a baseline network bandwidth of 1 Gbps and no local SSDs, this instance represents a low-resource, compute-focused tier. It is best suited for lightweight, dedicated single-threaded processing, basic web serving, and utility tasks that do not require high memory density or intensive storage I/O.

      Workload Profiles

      0.14Score
      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.
