    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring exceptional single-core clock speeds and high memory density for specialized, low-concurrency workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX4-2mds_v2 is a memory-intensive virtual machine featuring 2 vCPUs across 1 physical Intel Xeon 8573C core clocked at 4.2 GHz. It is equipped with 84.0 GB of RAM, a 260 MB L3 cache, and a 236 GB local NVMe SSD. Operating on the Microsoft Hyper-V hypervisor, this x86_64 server delivers top-tier single-core performance, as evidenced by a Geekbench single-core score of 2342.0 and strong single-threaded gzip compression. However, its multi-core performance is limited by the single physical core design, resulting in lower multi-threaded benchmark scores. With an exceptional memory-to-core ratio of 42 GB per vCPU, this instance is qualitatively optimized for memory-heavy, low-concurrency workloads. It is highly suited for memory-intensive databases, caching systems, and single-threaded analytical applications requiring a substantial memory footprint without the need for high parallel compute scaling.

    Workload Profiles

    0.31Score
    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.
