    CPU and System Topology

    Server Description

    An AMD-powered virtual machine offering a high memory-to-core ratio and local SSD storage for memory-bound enterprise workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E8a_v4 is a memory-optimized virtual machine instance powered by an AMD EPYC 7452 processor with 8 dedicated vCPUs and 64.0 GB of RAM. Operating on the x86_64 architecture under Microsoft Hyper-V, this server provides a high memory-to-vCPU ratio of 8.0 GB per core and includes 205 GB of local SSD storage. While synthetic benchmarks indicate weak raw CPU and large-block memory write performance, the instance delivers average results in real-world application tests, such as database operations, Redis SET transactions, and static web serving. The E8a_v4 represents a cost-efficient choice for memory-intensive workloads that do not demand extreme compute power, making it well-suited for relational databases, caching layers, and general enterprise applications.

    Workload Profiles

    0.41Score
    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.
