    CPU and System Topology

    Server Description

    A high-frequency, memory-dense virtual machine featuring one terabyte of RAM and advanced matrix extensions for demanding database and memory-bound workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    Microsoft Azure M128-64bs_v3 is a memory-optimized virtual machine from the MBSMediumMemoryv3 family, powered by a 64-vCPU Intel Xeon 8473C processor running at 4.0 GHz. Built on x86_64 architecture with 32 physical cores, it features 1024.0 GB of RAM, providing a high 16.0 GB of memory per core. The server lacks local storage and GPUs, relying entirely on external block storage. Benchmarks show top-tier performance in memory bandwidth, with read speeds of 365.6 GB/sec and write speeds of 173.16 GB/sec, alongside strong database operations and static web serving throughput. This configuration is highly efficient for memory-intensive applications, large databases, and in-memory caching, though users must account for the lack of local storage.

    Workload Profiles

    4.16Score
    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.
