    Server Description

    A balanced general-purpose instance combining AMD multi-core processing with high-capacity local NVMe SSD storage for data-intensive workloads.

    General PurposeStorage & Database

    Amazon Web Services m5ad.12xlarge is a general-purpose instance featuring an AMD EPYC 7571 processor with 48 vCPUs, 24 physical cores, and 192.0 GB of DDR4 RAM. It includes 1800 GB of local NVMe SSD storage and a 10 Gbps baseline network speed. Benchmark data reveals a performance tradeoff: single-core CPU performance and single-threaded tasks like gzip compression rank in the bottom 10%, whereas multi-core capabilities, Passmark CPU scores, and memory bandwidth consistently perform in the average middle 50% tier. Notably, the Passmark CPU encryption test shows strong performance in the top 25%. Qualitatively, the instance provides balanced resource density, combining dedicated compute with high-capacity local storage. It is suited for multi-threaded workloads, static web serving, and database operations requiring local scratch space, rather than single-threaded or high-demand LLM inference tasks.

    Workload Profiles

    1.1Score
    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.
