    CPU and System Topology

    Server Description

    A memory-intensive virtual machine featuring dedicated AMD EPYC cores and high memory density for database and text processing workloads.

    Memory OptimizedGeneral Purpose

    The Microsoft Azure F4ams_v6 is a memory-intensive virtual machine from the Famsv6 family, powered by a 3.7 GHz AMD EPYC 9V74 processor with 4 dedicated physical cores on the x86_64 architecture. It features 32.0 GB of RAM, providing a high 8.0 GB per vCPU ratio, but includes no local storage. Benchmarks show strong single-core CPU and text processing performance, alongside average multi-core and database execution speeds. However, uncached large-block memory read bandwidth is a performance bottleneck, landing in the bottom 25%. Lacking a GPU and local disks, this instance is qualitatively cost-efficient for memory-heavy workloads relying on external premium storage. It is best suited for database operations, text processing, and moderate memory-bound applications.

    Workload Profiles

    0.464Score
    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.
