    CPU and System Topology

    Server Description

    A memory-intensive virtual server featuring high memory density, dedicated Intel Xeon cores, and local NVMe storage for memory-bound workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX4mds_v2 is a memory-intensive virtual server configured with 4 dedicated vCPUs from an Intel Xeon 8573C processor running at 4.2 GHz, 84.0 GB of RAM, and a 236 GB local NVMe SSD. Operating on the Microsoft Hyper-V hypervisor, this x86_64 instance features a high memory-to-core ratio of 21.0 GB per core and a large 260 MB L3 cache. Benchmarks show top-tier single-core performance, though multi-core compute and uncached memory bandwidth are relatively weak. This hardware profile makes the server a qualitatively cost-efficient choice for memory-bound workloads that do not require high parallel processing power. It is best suited for in-memory caching, database operations, and single-threaded data processing.

    Workload Profiles

    0.54Score
    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.
