    Server Description

    A balanced general-purpose instance featuring AMD EPYC processors, 192 GB of DDR4 memory, and high-speed local NVMe SSD storage.

    General PurposeStorage & Database

    Amazon Web Services m5ad.12xlarge is an x86_64 general-purpose instance featuring 48 vCPUs (24 physical cores) powered by an AMD EPYC 7571 processor running at 2.2 GHz. It is equipped with 192.0 GB of DDR4 memory and 1800 GB of local NVMe SSD storage, operating on the Nitro hypervisor with a 10 Gbps baseline network speed. Performance benchmarks reveal a contrast between poor single-core execution and average multi-core capabilities, with strong cryptographic performance in the top 25%. The instance delivers average memory bandwidth and database throughput. Given its balanced vCPU-to-RAM ratio and fast local instance storage, the m5ad.12xlarge is suited for multi-threaded workloads, database operations, and web serving applications that benefit from local NVMe scratch space but do not require high single-threaded performance.

    Workload Profiles

    1.15Score
    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.
