    CPU and System Topology

    Server Description

    A high-frequency, memory-dense virtual server optimized for memory-intensive enterprise workloads and large in-memory database applications.

    Memory OptimizedGeneral Purpose

    Microsoft Azure FX12-6ms_v2 is a memory-optimized virtual machine from the FXmsv2 family, powered by a dedicated 4.2 GHz Intel Xeon 8573C processor. Operating on the Microsoft Hyper-V hypervisor, this x86_64 server provides 6 vCPUs across 3 physical cores and an extensive 252.0 GB of RAM, yielding 42.0 GB of memory per core. It features no local storage or GPU resources but is premium storage capable. Benchmarks highlight exceptional single-core capabilities, with Geekbench single-core and text processing scores reaching the top 10% tier, alongside strong single-threaded compression speeds. Conversely, multi-core metrics and large-model LLM inference speeds remain average to weak. This configuration represents a highly specialized, memory-dense profile designed for workloads that prioritize RAM capacity over raw core counts. It is best suited for in-memory databases, large-scale caching, and memory-intensive enterprise applications.

    Workload Profiles

    0.744Score
    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.
