    Server Description

    A balanced general-purpose instance featuring AMD EPYC processors, 64 GB DDR4 RAM, and a bundled 600 GB local NVMe SSD.

    Amazon Web Services m5ad.4xlarge is a general-purpose instance featuring 16 dedicated vCPUs and 8 physical cores powered by an AMD EPYC 7571 processor running at 2.2 GHz. It is configured with 64.0 GB of DDR4 memory and a bundled 600 GB NVMe SSD local instance store, operating on the AWS Nitro hypervisor with a 5 Gbps baseline network speed. Performance benchmarks reveal a distinct tradeoff: single-core CPU execution and uncached memory bandwidth are weak, ranking in the bottom 10% to 25%, whereas multi-core CPU metrics, Passmark database operations, and Redis SET operations achieve average tier results. This hardware profile is qualitatively cost-efficient for multi-threaded applications and moderate database workloads that benefit from local NVMe scratch space but do not require high single-threaded compute performance.

    Workload Profiles

    0.47Score
    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.
