    CPU and System Topology

    Server Description

    A high-density, memory-optimized virtual machine featuring sixty-four dedicated vCPUs and five hundred twelve gigabytes of RAM for demanding enterprise workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure E64_v5 is a memory-optimized virtual machine from the Ev5 family, powered by a 2.8 GHz Intel Xeon 8370C processor. It features 64 dedicated vCPUs (32 physical cores), 512.0 GB of RAM, and a 105 MB L3 cache, with no local storage or GPUs. Operating on Microsoft Hyper-V, it delivers strong multi-core CPU performance, high memory bandwidth, and excellent database operations. While single-core tasks and large-model text generation show average to weak performance, its high memory-to-core ratio of 8.0 GB per vCPU provides strong qualitative cost efficiency for memory-intensive applications. It is best suited for large databases, multi-threaded data processing, and enterprise workloads.

    Workload Profiles

    3.12Score
    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.
