    CPU and System Topology

    Server Description

    A compute-optimized server featuring sixty-four high-frequency Intel Xeon vCPUs, low memory density, and fast local NVMe SSD storage.

    Compute OptimizedStorage & Database

    Microsoft Azure D64lds_v7 is an x86_64 server powered by a 4.2 GHz Intel Xeon 6973P-C processor with 64 dedicated vCPUs and 128.0 GB of RAM. This low-memory configuration provides 2.0 GB of memory per core alongside 3780 GB of local NVMe SSD storage. The server exhibits strong multi-core performance, as evidenced by a PassMark CPU score of 83685.33 and a stress-ng multi-core score of 67973.49. It also delivers strong memory bandwidth, reaching 311.23 GB/sec for uncached large blocks, and processes 109.21 million Redis SET operations per second. While the low memory-to-core ratio represents a tradeoff for memory-heavy tasks, the high-frequency CPU and fast local storage offer qualitative cost efficiency for compute-intensive workloads. It is well-suited for database operations, multi-threaded data decompression, high-throughput web serving, and CPU-based machine learning inference.

    Performance

    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.
