      CPU and System Topology

      Server Description

      A compute-optimized instance featuring sixty-four dedicated Intel Xeon vCPUs and low memory density for high-throughput, CPU-bound processing.

      Compute Optimized

      Microsoft Azure D64ls_v7 is an x86_64 compute-optimized virtual machine featuring 64 dedicated vCPUs and 32 physical cores powered by an Intel Xeon 6973P-C processor running at 4.2 GHz. Equipped with 128.0 GB of RAM, it maintains a low memory-to-core ratio of 2.0 GB per vCPU. The instance lacks local storage but is Premium Storage capable, and it includes no GPUs. Benchmark results show top-tier CPU performance, with a PassMark score of 87,182.31, alongside strong multi-core capabilities and high memory bandwidth. Supported by Intel AMX and AVX-512 instruction sets, it excels in cryptographic tasks, multi-threaded decompression, and static web serving. The low memory density makes it a cost-efficient option for compute-bound workloads, such as database operations and batch processing, where large memory allocations are unnecessary.

      Workload Profiles

      4.3Score
      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.
