    CPU and System Topology

    Server Description

    A balanced general-purpose virtual machine featuring high-frequency AMD EPYC processing and fast local NVMe SSD storage for diverse workloads.

    General PurposeStorage & Database

    Microsoft Azure D4ads_v7 is a general-purpose virtual machine from the Dadsv7 family, powered by a 4.5 GHz AMD EPYC 9V45 processor. It features 4 dedicated vCPUs, 16.0 GB of RAM, and a bundled 236 GB NVMe SSD. Operating on the Microsoft Hyper-V hypervisor, this instance delivers top-tier single-core CPU performance and single-threaded compression speeds. However, multi-threaded scaling is average, and medium-model LLM prompt processing is poor. With a balanced 1:4 vCPU-to-RAM ratio and local NVMe storage, the D4ads_v7 provides qualitative cost efficiency for general-purpose workloads, static web serving, and database operations, while avoiding the higher costs of specialized compute or memory-optimized instances.

    Performance

    Workload Profiles

    0.41Score
    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.
