      CPU and System Topology

      Server Description

      A high-density compute-optimized instance delivering strong multi-threaded performance and high uncached memory bandwidth for core-heavy workloads.

      Compute Optimized

      Microsoft Azure D64ls_v5 is a compute-optimized virtual machine equipped with 64 vCPUs (32 physical Intel Xeon 8370C cores running at 2.8 GHz) and 128 GB of RAM, yielding a low-memory 1:2 vCPU-to-RAM ratio. Built on x86_64 architecture and running under Microsoft Hyper-V, it provides dedicated CPU allocation with AVX-512 instruction support. The instance lacks attached local SSD storage and integrated GPU acceleration. Performance testing highlights strong multi-core CPU results, including high PassMark CPU, software compilation, and uncached memory bandwidth scores, while single-core metrics remain average. Dedicated memory bandwidth reaches 292.88 GB/sec for large block reads. Highly cost-efficient for parallelized, CPU-heavy execution without large memory footprints, the instance excels at software compilation, static web serving, and database processing. However, it displays limited throughput during large LLM inference tasks.

      Workload Profiles

      3.1Score
      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.
