    CPU and System Topology

    Server Description

    A compute-optimized virtual machine featuring dedicated Intel Xeon cores and a 1:2 memory-to-vCPU ratio for multi-threaded workloads.

    Compute OptimizedGeneral Purpose

    Microsoft Azure F8s is an FS-family virtual machine featuring 8 dedicated vCPUs and 8 physical cores powered by an Intel Xeon 8171M processor running at 2.6 GHz. Built on the x86_64 architecture under the Microsoft Hyper-V hypervisor, it includes 16.0 GB of memory (2.0 GB per core) and a 33 GB local storage volume with Premium Storage capability. Performance benchmarks show a contrast between weak single-core execution and average multi-core capabilities, with Passmark CPU, Geekbench multi-core, and Redis SET operations all scoring in the middle 50 percent. This compute-optimized configuration is well-suited for multi-threaded workloads such as software compilation, image processing, ray tracing, and moderate database operations where a 1:2 memory-to-vCPU ratio is sufficient.

    Workload Profiles

    0.486Score
    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.
