    Server Description

    A balanced general-purpose platform featuring high-speed local NVMe storage, robust multi-core capabilities, and high-throughput baseline networking.

    General PurposeStorage & Database

    Amazon Web Services m5dn.16xlarge is a general-purpose, network-optimized instance featuring 64 dedicated vCPUs and 32 physical cores powered by an Intel Xeon 8259CL processor running at 3.1 GHz. It is configured with 256.0 GB of DDR4 memory and 2400 GB of local NVMe SSD storage, supported by a 75 Gbps baseline network bandwidth. Benchmark data indicates a tradeoff: single-core performance and single-threaded compression tasks are relatively weak, whereas large-block memory bandwidth and multi-core extended instruction execution are strong. Qualitatively, this instance provides a balanced resource profile with high-speed local storage and high network throughput, making it cost-efficient for multi-threaded applications. It is well-suited for database operations, static web serving, and general-purpose enterprise workloads that benefit from high-speed local storage and high network capacity.

    Workload Profiles

    2.2Score
    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.
