    Server Description

    A high-density AMD EPYC virtual machine balancing sixty-four vCPUs with substantial memory and local storage for parallelized enterprise workloads.

    General PurposeStorage & Database

    Microsoft Azure D64a_v4 is a general-purpose virtual machine from the DAv4 family, configured with 64 vCPUs, 32 physical AMD EPYC 7452 cores, 256.0 GB of RAM, and 1638 GB of local storage. Operating on Microsoft Hyper-V, this server delivers a balanced 1:4 vCPU-to-RAM ratio. While single-core performance is limited, placing in the bottom 10% for stress-ng tests, its multi-core and memory capabilities are highly competitive. The server achieves top 25% rankings in Geekbench multi-core, Passmark CPU, and multi-threaded bzip3 decompression, alongside a top 10% Passmark memory score. This resource profile makes the D64a_v4 a cost-efficient option for parallelized workloads, including database operations, software compilation, and multi-threaded data processing, where high core density and memory bandwidth are prioritized over single-threaded speed.

    Workload Profiles

    2.09Score
    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.
