    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring high RAM density, dedicated AMD EPYC processing, and local SSD storage for memory-intensive enterprise workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E64-32as_v4 is a memory-optimized virtual machine from the EASv4 family, powered by an AMD EPYC 7763 processor running at 3.525 GHz. It features 32 dedicated vCPUs, 512.0 GB of RAM, and an 885 GB local SSD. Operating under Microsoft Hyper-V, this instance delivers strong single-core CPU and memory performance, as evidenced by its top-tier PassMark memory score and stress-ng single-core results. While multi-core processing and memory bandwidth remain average, its high memory density makes it highly cost-efficient for memory-bound workloads. However, it exhibits weak performance on large-scale LLM inference tasks. This server is best suited for memory-intensive applications, including large databases, in-memory caches, and data processing pipelines.

    Workload Profiles

    1.3Score
    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.
