    CPU and System Topology

    Server Description

    A high-frequency, memory-intensive virtual machine with dedicated Intel Xeon cores and local NVMe SSD storage for demanding database workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    Microsoft Azure FX12mds_v2 is a memory-optimized virtual machine powered by an Intel Xeon 8573C processor with 12 dedicated vCPUs operating at 4.2 GHz. It features 252.0 GB of RAM, yielding a high resource density of 21.0 GB per core, alongside 945 GB of local NVMe SSD storage. Running on Microsoft Hyper-V, the instance delivers top-tier single-core performance, as evidenced by a Geekbench single-core score of 2358.0 and strong single-threaded compression throughput. The processor supports advanced instruction sets including AVX-512 and Intel AMX for accelerated matrix operations. With its high memory capacity, fast clock speed, and local NVMe storage, the FX12mds_v2 is optimized for memory-intensive databases, text processing, and workloads requiring strong single-threaded execution.

    Workload Profiles

    1.3Score
    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.
