    CPU and System Topology

    Server Description

    A memory-intensive server featuring dedicated Intel Xeon processors, massive RAM capacity, and high-speed local NVMe storage for enterprise database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX64mds_v2 is a memory-optimized server in the FXmdsv2 family, running on the Microsoft Hyper-V hypervisor. It features 64 dedicated vCPUs from a 32-core Intel Xeon 8573C processor running at 4.2 GHz, paired with 1344.0 GB of RAM and a 3780 GB NVMe SSD. The architecture supports AVX-512 and Intel AMX instructions. Benchmarks indicate top-tier performance in large-block memory bandwidth (392.4 GB/sec read) and database operations, alongside strong multi-core CPU execution. While single-core performance is average, the high memory-to-vCPU ratio of 21.0 GB per core offers qualitative cost efficiency for memory-intensive deployments. This server is configured for in-memory databases, large-scale data processing, and enterprise application hosting.

    Workload Profiles

    4.3Score
    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.
