    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring a high RAM-to-vCPU ratio, dedicated AMD EPYC processing, and local storage for data-intensive workloads.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Microsoft Azure E64-16as_v4 is an EASv4-series virtual machine featuring 16 dedicated vCPUs and 512.0 GB of RAM, powered by an AMD EPYC 7763 processor operating at 3.525 GHz. Built on the x86_64 architecture and managed via Microsoft Hyper-V, this instance includes 885 GB of local storage and is Premium Storage capable. Benchmark results show strong single-core CPU performance and a strong PassMark memory score, both placing in the top 25%. Conversely, large block memory write bandwidth is a relative bottleneck, performing in the bottom 25%. With a high memory-to-vCPU ratio of 32 GB per vCPU, this configuration is optimized for memory-intensive workloads such as in-memory databases, caching layers, and data-heavy enterprise applications where RAM capacity is prioritized over raw multi-core compute scaling.

    Workload Profiles

    0.72Score
    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.
