    CPU and System Topology

    Server Description

    Balanced four-vCPU AMD EPYC virtual machine with integrated NVMe storage, delivering strong single-thread execution for enterprise workloads.

    General PurposeStorage & Database

    Microsoft Azure D4ads_v6 is a general-purpose instance featuring 4 dedicated vCPUs powered by a 3.7 GHz AMD EPYC 9V74 processor on the x86_64 architecture. Equipped with 16.0 GB of RAM and 236 GB of integrated local NVMe SSD storage, the instance maintains a balanced 1:4 core-to-memory ratio. Benchmark results show strong single-threaded performance, with top-tier single-core CPU scores in stress-ng and Geekbench. Multi-threaded processing and web serving throughput demonstrate steady mid-tier capability, achieving 5.92 million Redis SET operations per second and 6.43 GB/sec static web throughput. Read memory bandwidth is lower relative to core performance, making the instance most effective for web serving, microservices, lightweight databases, and general enterprise workloads needing direct local disk speed without requiring heavy memory bandwidth or GPU acceleration.

    Workload Profiles

    0.36Score
    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.
