    CPU and System Topology

    Server Description

    A high-density, general-purpose virtual machine delivering top-tier AMD EPYC compute performance and balanced memory for demanding enterprise workloads.

    General PurposeCompute Optimized

    The Microsoft Azure D128as_v7 is a general-purpose virtual machine from the Dasv7 family, built on the x86_64 architecture and powered by an AMD EPYC 9V45 processor. It features 128 vCPUs across 64 physical cores running at 4.5 GHz, paired with 512.0 GB of system memory. This configuration lacks local storage and GPU accelerators, relying instead on external Premium Storage. Benchmarks place this instance in the top tier for both single-core and multi-core CPU performance, as well as memory bandwidth and database operations. The processor supports advanced vector and cryptographic instructions, enabling high-throughput tasks such as Redis operations, static web serving, and CPU-based LLM inference. The D128as_v7 is suited for enterprise-grade general-purpose applications, multi-threaded database workloads, and high-volume web serving.

    Workload Profiles

    4.9Score
    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.
