    Server Description

    A memory-optimized x86_64 platform featuring dedicated AMD EPYC processing and top-tier memory performance for database and multi-threaded workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure EC64as_cc_v5 is an x86_64 memory-optimized server featuring a dedicated AMD EPYC 7763 processor with 64 vCPUs, 32 physical cores, and a clock speed of 3.525 GHz. It is configured with 512.0 GB of RAM, yielding 8.0 GB of memory per vCPU, but contains no local storage or GPUs. Operating under Microsoft Hyper-V, the server delivers top-tier memory performance and strong multi-core processing capabilities, as evidenced by its top 10% PassMark memory score and top 25% multi-core stress-ng results. Tradeoffs include average uncached large-block memory bandwidth and weak performance in large-model LLM text generation. This hardware profile is qualitatively cost-efficient for memory-heavy applications that do not require local NVMe drives. It is suited for database operations, Redis caching, and multi-threaded data processing.

    Workload Profiles

    2.14Score
    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.
