    CPU and System Topology

    Server Description

    A high-frequency, memory-intensive virtual machine featuring dedicated Intel Xeon cores, massive RAM density, and integrated local storage for demanding workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure FX12mds_v2 is a memory-optimized virtual machine featuring 12 dedicated vCPUs from an Intel Xeon 8573C processor running at 4.2 GHz. Built on the x86_64 architecture with Hyper-V virtualization, it delivers 252.0 GB of RAM (21.0 GB per core) and includes a 945 GB local disk. The processor features a 260 MB L3 cache and supports AMX and AVX-512 instruction sets. Benchmarks highlight top-tier single-core performance, with Geekbench single-core and text processing scores in the top 10% tier, alongside strong single-threaded decompression. Multi-core and database benchmarks perform in the average tier, with Redis SET operations reaching 19.38 million operations per second. This instance provides high memory density relative to its core count, making it highly suitable for memory-intensive databases, text processing, and caching workloads.

    Workload Profiles

    1.31Score
    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.
