    CPU and System Topology

    Server Description

    A balanced general-purpose virtual machine featuring dedicated AMD EPYC processing, strong single-core performance, and premium external storage compatibility.

    General Purpose

    Microsoft Azure D4as_v6 is a general-purpose virtual machine from the Dav6 family, powered by an AMD EPYC 9V74 x86_64 processor. It features 4 dedicated vCPUs across 2 physical cores running at 3.7 GHz, paired with 16.0 GB of RAM. The instance lacks local storage and GPUs but supports Premium Storage. Performance benchmarks highlight strong single-core capabilities, with stress-ng and Geekbench single-core scores in the top 25%. However, memory read bandwidth is relatively weak, scoring in the bottom 25%. This server is qualitatively cost-efficient for balanced workloads such as static web serving, text processing, and general-purpose application hosting, while being less suitable for memory-bound databases or heavy multi-threaded compilation.

    Workload Profiles

    0.352Score
    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.
