      CPU and System Topology

      Server Description

      A high-frequency, compute-dense virtual machine featuring advanced matrix extensions and low memory-to-core ratios for parallel processing workloads.

      Compute OptimizedGeneral Purpose

      Microsoft Azure D64nls_v6 is an x86_64 virtual machine from the Dnlv6 family, powered by a 64-vCPU Intel Xeon 8573C processor running at 4.2 GHz on Microsoft Hyper-V. It features 128.0 GB of memory, resulting in a low memory-to-core ratio of 2.0 GB per vCPU, and contains no local storage or GPUs. Benchmarks show top-tier multi-core performance, with a Geekbench multi-core score of 21,489.0 and strong memory bandwidth of 244.26 GB/sec for large block reads. The processor supports AVX-512 and Intel AMX extensions, facilitating strong performance in cryptography, image processing, and LLM inference. The lack of local storage and low memory density represent key tradeoffs, but the high compute density makes it cost-efficient for CPU-bound tasks. It is suited for network-optimized applications, software compilation, static web serving, and parallelized compute workloads.

      Workload Profiles

      3.2Score
      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.
