    CPU and System Topology

    Server Description

    A high-frequency, memory-intensive virtual server featuring one terabyte of RAM and advanced matrix extensions for demanding enterprise workloads.

    Memory OptimizedCompute Optimized

    Microsoft Azure FX48ms_v2 is a memory-intensive virtual machine from the FXmsv2 family, running on the Microsoft Hyper-V hypervisor. It features a dedicated Intel Xeon 8573C x86_64 processor with 48 vCPUs (24 physical cores) operating at 4.2 GHz, supported by a 260 MB L3 cache. The instance provides 1008.0 GB of RAM, translating to 21.0 GB per core, but includes no local storage or bundled GPUs. Benchmarks indicate strong memory bandwidth, with uncached large-block reads at 331.05 GB/sec, and top-tier single-core performance in image and text processing. The processor's support for AVX-512 and AMX instructions enhances its capability for mathematical and cryptographic operations. This server is designed for memory-heavy and compute-intensive workloads such as large database operations, in-memory caching, and CPU-based machine learning inference.

    Workload Profiles

    3.76Score
    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.
