    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring dedicated Intel Xeon cores and high memory density for database and caching workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure GS4 is an x86_64 virtual machine featuring 16 dedicated physical cores and 16 vCPUs powered by an Intel Xeon E5-2698B v3 processor running at 2.0 GHz. It is configured with 224.0 GB of RAM, offering a high memory-to-core ratio of 14.0 GB, alongside 459 GB of local storage. Benchmark results show poor single-core performance and weak uncached memory write bandwidth, but average multi-core CPU performance and database operations. The instance lacks GPU acceleration and AVX-512 support. Qualitatively, the GS4 provides high memory density at the expense of modern single-thread processing speeds. It is best suited for memory-intensive workloads such as database operations, Redis caching, and static web serving.

    Workload Profiles

    0.47Score
    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.
