    CPU and System Topology

    Server Description

    A high-frequency, memory-intensive virtual machine featuring an exceptional RAM-to-core ratio and fast local NVMe storage for demanding database workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    The Microsoft Azure FX64-16mds_v2 is a memory-optimized virtual machine from the FXmdsv2 family, built on the Microsoft Hyper-V hypervisor. It features an x86_64 Intel Xeon 8573C processor with 16 dedicated vCPUs running at 4.2 GHz, paired with an exceptionally large 1344.0 GB of RAM and 3780 GB of local NVMe SSD storage. Benchmark results show top-tier single-core CPU and text processing performance, alongside strong large-block memory write bandwidth. With its massive memory-to-core ratio of 84.0 GB per core, this instance provides high qualitative cost efficiency for memory-bound workloads by minimizing core-licensing costs. It is highly suited for in-memory databases, large-scale data analytics, and enterprise applications requiring high single-thread performance and substantial local storage.

    Performance

    Workload Profiles

    1.5Score
    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.
