    CPU and System Topology

    Server Description

    A burstable, cost-efficient virtual machine with balanced memory and Intel Xeon processing for variable, low-to-moderate computing workloads.

    Burstable & BudgetGeneral Purpose

    Microsoft Azure B4s_v2 is a burstable virtual machine in the Bsv2 family, configured with 4 vCPUs and 16.0 GB of RAM. Powered by an Intel Xeon 8370C processor running at 2.8 GHz on the x86_64 architecture, this instance utilizes Microsoft Hyper-V virtualization. It features 2 physical cores with hyper-threading and a 48 MB L3 cache, but lacks local storage and GPU resources. Performance benchmarks show average single-core capabilities, with a Geekbench single-core score of 1674.0, but weaker multi-core and memory bandwidth results. The burstable CPU allocation makes this instance a cost-efficient option for workloads with variable CPU demands. It is best suited for general-purpose applications, development environments, light web serving, and small-scale background processes that do not require sustained high-compute performance.

    Workload Profiles

    0.371Score
    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.
