    CPU and System Topology

    Server Description

    A balanced general-purpose instance featuring dedicated AMD EPYC processing, strong single-core execution, and premium storage compatibility for lightweight workloads.

    General Purpose

    Microsoft Azure D4as_v4 is a general-purpose virtual machine from the DASv4 family, powered by an AMD EPYC 7763 processor running at 3.35 GHz on the x86_64 architecture. It features 4 dedicated vCPUs, 16.0 GB of RAM, and 33 GB of local storage with Premium Storage capability. Performance benchmarks indicate strong single-core CPU performance, placing in the top 25%, alongside average single-threaded compression and encryption capabilities. However, the instance exhibits weaker multi-core scaling and low memory bandwidth, with multi-core benchmarks and database operations falling into the bottom 25%. This hardware profile is qualitatively cost-effective for general-purpose workloads, single-threaded applications, and lightweight web serving, but is less suited for memory-intensive databases or heavy multi-threaded processing.

    Workload Profiles

    0.279Score
    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.
