    Server Description

    A high-core AMD EPYC virtual machine delivering balanced compute and memory resources with dedicated performance for multi-threaded enterprise workloads.

    General Purpose

    The Microsoft Azure D64as_v4 is a general-purpose virtual machine from the DASv4 family, powered by an AMD EPYC 7763 processor with 64 dedicated vCPUs running at 3.525 GHz. It features 256.0 GB of RAM, a 524 GB local storage disk, and is Premium Storage capable. Operating on the Microsoft Hyper-V hypervisor, this x86_64 server delivers strong multi-core CPU performance, placing in the top 25% of benchmarks for multi-threaded tasks, ray tracing, and image processing. While cached memory bandwidth is exceptionally high, uncached large-block memory operations and database transactions perform at average levels. Lacking a dedicated GPU, it remains highly capable for CPU-bound workloads. The D64as_v4 is best suited for multi-threaded enterprise applications, software compilation, and moderate database operations requiring a balanced vCPU-to-RAM ratio.

    Workload Profiles

    2.04Score
    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.
