    CPU and System Topology

    Server Description

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

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Microsoft Azure E64as_v4 is an x86_64 memory-optimized virtual machine powered by a dedicated AMD EPYC 7763 processor. It features 64 vCPUs, 32 physical cores, 512 GB of RAM, and an 885 GB local SSD. Operating on Microsoft Hyper-V, this server delivers strong multi-core processing and top-tier memory performance, as evidenced by high Passmark memory scores and 62.62 million Redis SET operations per second. While cached memory bandwidth is strong, uncached memory bandwidth remains average. Additionally, the lack of a GPU results in weak performance for large-scale LLM text generation. This server is highly cost-efficient for memory-intensive workloads, making it best suited for database hosting, in-memory caching, and large-scale software compilation.

    Workload Profiles

    2.1Score
    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.
