    Server Description

    A balanced general-purpose platform combining dedicated AMD EPYC processors with high-capacity local NVMe SSD storage for multi-threaded workloads.

    General PurposeStorage & Database

    The Amazon Web Services m5ad.16xlarge is a general-purpose instance built on the Nitro hypervisor, featuring a 64-vCPU AMD EPYC 7571 processor and 256 GB of DDR4 memory. It includes 2400 GB of local NVMe SSD storage and a 12 Gbps baseline network speed. While single-core benchmarks place the instance in the bottom 10% due to its 2.5 GHz clock speed, its multi-core and cryptographic capabilities perform at average to strong levels, with Passmark encryption scoring in the top 25%. The balanced 1:4 vCPU-to-RAM ratio combined with high-capacity local NVMe storage makes this instance a cost-efficient choice for multi-threaded workloads, database operations, and web serving that require fast local scratch space, though it is less suited for single-threaded or intensive machine learning inference tasks.

    Workload Profiles

    1.44Score
    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.
