    CPU and System Topology

    Server Description

    A memory-optimized virtual server featuring one terabyte of RAM and sixty-four dedicated vCPUs for demanding database and enterprise workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure M64s is a memory-optimized server instance designed for resource-intensive enterprise workloads. Powered by an Intel Xeon 8280M processor on the x86_64 architecture, it delivers 64 dedicated vCPUs across 32 physical cores, paired with 1024.0 GB of RAM and 2097 GB of local storage. While single-core benchmarks place the instance in the bottom 10%, its multi-core and memory bandwidth capabilities are highly competitive, with large-block memory read speeds and multi-threaded decompression performance ranking in the top 25%. This hardware profile offers high memory density, making it qualitatively cost-effective for memory-bound applications rather than compute-heavy single-threaded tasks. The M64s is highly suited for large-scale databases, in-memory caching, and parallelized data processing workloads.

    Workload Profiles

    1.73Score
    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.
