    CPU and System Topology

    Server Description

    A memory-optimized server combining high RAM density, fast local NVMe storage, and strong single-core performance for demanding database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E64-16ads_v7 is a memory-optimized virtual machine featuring 16 dedicated vCPUs powered by an AMD EPYC 9V45 processor running at 4.5 GHz. It is configured with 512.0 GB of RAM, providing an exceptionally high 32.0 GB of memory per core, alongside 3780 GB of local NVMe SSD storage. Operating on the Microsoft Hyper-V hypervisor, this instance excels in single-core CPU tasks, placing in the top 10% for single-core stress-ng and compression benchmarks. While multi-core performance and large-block memory bandwidth are average, its PassMark memory score is strong. The high memory-to-vCPU ratio and fast local storage make this server highly efficient for memory-intensive workloads, such as in-memory databases, caching layers, and data analytics, where massive RAM capacity is required without the cost of additional compute cores.

    Workload Profiles

    1Score
    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.
