    CPU and System Topology

    Server Description

    A dedicated AMD EPYC virtual machine with bundled SSD storage, delivering strong single-core performance for balanced, everyday computing workloads.

    General Purpose

    The Microsoft Azure D4a_v4 is an x86_64 general-purpose virtual machine utilizing the Microsoft Hyper-V hypervisor. It is powered by an AMD EPYC 7763 processor running at 3.525 GHz, configured with 4 dedicated vCPUs (2 physical cores with hyperthreading) and 16.0 GB of RAM. The instance includes a bundled 102 GB local SSD but lacks GPU capabilities. Benchmarks reveal a strong single-core CPU performance (top 25% in stress-ng), contrasted by weaker multi-core scaling and memory write bandwidth, which fall into the bottom 25%. This hardware profile offers a cost-efficient option for workloads requiring dedicated CPU resources without massive parallelization. It is best suited for general-purpose tasks, lightweight web serving, single-threaded data processing, and development environments.

    Workload Profiles

    0.27Score
    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.
