    CPU and System Topology

    Server Description

    An entry-level virtual machine with dedicated Intel cores and local storage, configured for low-intensity development and basic utility workloads.

    Compute OptimizedGeneral Purpose

    Microsoft Azure A4_v2 is an entry-level virtual machine from the Av2 family, utilizing an Intel Xeon E5-2673 v4 processor with an x86_64 architecture. It features 4 dedicated physical cores and 4 vCPUs running at 2.3 GHz, paired with 8.0 GB of RAM and 41 GB of local storage. The server does not include a GPU. Across standardized benchmarks, including stress-ng and Geekbench, the A4_v2 consistently performs in the bottom 10% for both compute and memory bandwidth, with large-block memory reads reaching 12.94 GB/sec. Given these performance constraints, this server is positioned as a budget-friendly option for low-intensity workloads. It is best suited for basic web serving, light development tasks, and non-critical testing environments rather than resource-heavy database or computational applications.

    Workload Profiles

    0.093Score
    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.
