    CPU and System Topology

    Server Description

    An AMD-powered virtual machine offering high memory density and local storage for memory-bound workloads and database caching.

    Memory OptimizedGeneral Purpose

    Microsoft Azure E8a_v4 is an x86_64 memory-optimized virtual machine from the EAv4 family, running on the Microsoft Hyper-V hypervisor. It features an AMD EPYC 7452 processor with 8 dedicated vCPUs operating at 3.35 GHz, paired with 64.0 GB of RAM and a 205 GB local storage drive. Benchmark results indicate average performance across standard operations, including a Geekbench multi-core score of 5142.0 and a Redis throughput of 7.1 million operations per second. However, CPU-heavy tasks show limitations, with stress-ng multi-core performance falling into the bottom 25%. This instance offers a high memory-to-core ratio, making it a qualitatively cost-effective option for memory-intensive workloads such as databases, caching layers, and general-purpose web serving that do not demand extreme raw processing power.

    Workload Profiles

    0.42Score
    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.
