    CPU and System Topology

    Server Description

    A storage-dense instance featuring high-capacity local NVMe SSDs, balanced memory, and strong single-core AMD EPYC processor performance.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    The Microsoft Azure L16aos_v4 is a storage-focused server instance powered by an AMD EPYC 9V74 processor running at 3.7 GHz. It features 16 dedicated vCPUs across 8 physical cores, 128.0 GB of RAM, and a substantial 11,519 GB of local NVMe SSD storage. Operating under the Microsoft Hyper-V hypervisor, the instance delivers strong single-core CPU and text processing performance, though its multi-core benchmarks and uncached large-block memory read bandwidth are average to weak. Lacking GPU acceleration, it is not designed for heavy AI workloads, as evidenced by poor large-model LLM inference speeds. However, its high local storage capacity and 8:1 memory-to-core ratio make it qualitatively cost-efficient for database hosting, data warehousing, and I/O-intensive workloads requiring rapid local storage access.

    Workload Profiles

    0.87Score
    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.
