    CPU and System Topology

    Server Description

    A high-capacity memory-optimized virtual machine featuring one terabyte of RAM and local SSD storage for large-scale database workloads.

    The Microsoft Azure M64s is a memory-optimized virtual machine featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8280M processor running at 2.7 GHz. Built on the x86_64 architecture under the Microsoft Hyper-V hypervisor, it delivers 1024 GB of RAM alongside 2097 GB of local SSD storage. While single-core benchmarks for this instance fall in the bottom 10%, its multi-core performance and database operations align with the middle 50% of tested servers. Notably, its large-block uncached memory bandwidth is strong, reaching 215.58 GB/sec. This high memory-to-CPU ratio makes the M64s qualitatively cost-efficient for memory-dense workloads. It is highly suited for large databases, enterprise applications, and memory-intensive data processing tasks where massive RAM capacity is prioritized over single-threaded execution speed.

    Workload Profiles

    1.7Score
    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.
