    CPU and System Topology

    Server Description

    A high-frequency, memory-optimized virtual machine featuring dedicated Intel Xeon processors and 512 GB of RAM for demanding database workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure M64bs_v3 is a memory-optimized virtual machine from the MBSMediumMemoryv3 family, powered by a dedicated Intel Xeon 8473C processor. Operating at 4.0 GHz, this x86_64 server provides 64 vCPUs across 32 physical cores, backed by 105 MB of L3 cache and 512.0 GB of RAM. It lacks local storage and GPUs, relying on premium block storage. Benchmarks show top-tier single-core performance with a Geekbench score of 2174.0 and strong memory bandwidth, reaching 4509.44 GB/sec for cached reads. The system is highly capable in transactional environments, delivering 71.51 million Redis SET operations per second and a Passmark database score of 29566.23. The M64bs_v3 is optimized for memory-heavy enterprise workloads, including relational databases, in-memory data stores, and large-scale data processing.

    Workload Profiles

    3.43Score
    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.
