    Server Description

    A high-frequency, memory-optimized virtual machine featuring advanced matrix extensions and dense memory allocation for demanding database and enterprise workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure M48bs_v3 is a memory-optimized virtual machine from the MBSMediumMemoryv3 family, powered by a 48-vCPU Intel Xeon 8473C processor running at 4.0 GHz. Built on the x86_64 architecture with Microsoft Hyper-V, it features 384.0 GB of RAM, yielding an 8.0 GB per core memory allocation. The instance lacks local storage and GPUs but supports premium block storage. Performance benchmarks show strong capabilities, including a Geekbench single-core score of 2183.0 and a multi-core score of 19356.0, alongside high memory bandwidth of 3826.53 GB/sec for cached reads. The processor supports advanced instruction sets like AVX-512 and AMX for accelerated matrix operations. This configuration is highly suited for memory-intensive database operations, enterprise application hosting, software compilation, and medium-scale data processing workloads.

    Workload Profiles

    3.05Score
    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.
