    Server Description

    A high-density memory-optimized virtual machine featuring dedicated AMD EPYC processing and local storage for demanding database and enterprise workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure E48as_v4 is an x86_64 memory-optimized virtual machine from the EASv4 family, powered by a dedicated AMD EPYC 7763 processor. It features 48 vCPUs running at 3.525 GHz, paired with 384.0 GB of RAM and 786 GB of local storage. Operating under Microsoft Hyper-V, the instance delivers strong multi-core CPU performance and high cryptographic throughput, as evidenced by top-tier stress-ng and Passmark benchmarks. While memory capacity is substantial at 8.0 GB per vCPU, uncached memory bandwidth and large-model LLM text generation represent relative performance tradeoffs. This hardware profile is highly cost-efficient for memory-heavy applications, making it an appropriate fit for relational databases, in-memory caching, data analytics, and enterprise web applications.

    Workload Profiles

    1.7Score
    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.
