    CPU and System Topology

    Server Description

    An x86_64 virtual machine combining a high memory-to-core ratio with dedicated Intel Xeon processing and local storage for memory-centric workloads.

    Memory OptimizedGeneral Purpose

    The Microsoft Azure DS12 is an x86_64 virtual machine instance within the DS family, powered by an Intel Xeon 8171M processor running at 2.6 GHz on the Microsoft Hyper-V hypervisor. It features 4 dedicated physical cores with 1 thread per core, 28.0 GB of system memory, and 57 GB of local storage. Benchmark data reveals a distinct performance profile: while CPU-centric metrics such as Geekbench and stress-ng scores fall into the bottom 25 percent, memory performance remains average, with solid memory bandwidth and Redis SET operations reaching 6.15 million operations per second. This instance offers qualitative cost efficiency for memory-heavy, compute-light workloads. It is best suited for memory-intensive general-purpose applications, caching layers, and lightweight database operations.

    Workload Profiles

    0.36Score
    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.
