    CPU and System Topology

    Server Description

    A network-optimized, compute-focused virtual machine featuring high-frequency Intel Xeon processors and a streamlined memory footprint for efficient parallel processing.

    Compute OptimizedGeneral Purpose

    Microsoft Azure D64nls_v6 is a network-optimized, low-memory virtual machine powered by a dedicated Intel Xeon 8573C processor. Operating at 4.2 GHz, this x86_64 architecture instance provides 64 vCPUs and 128.0 GB of RAM, resulting in a compute-focused 2.0 GB of memory per vCPU. While it lacks local storage and GPUs, it supports premium external storage. Benchmarks show strong performance, particularly in memory bandwidth, Passmark CPU tests, and Redis SET operations, which reach 72.31 million operations per second. The processor's support for AVX-512 and Intel AMX instructions drives strong performance in LLM prompt processing. The low memory-to-CPU ratio represents a tradeoff, making it less suitable for massive in-memory databases but highly cost-efficient for network-intensive applications, static web serving, and compute-heavy workloads.

    Workload Profiles

    3.28Score
    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.
