    Server Description

    A dedicated AMD EPYC instance featuring high memory density and strong single-core performance for memory-bound enterprise workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure EC20as_cc_v5 is an x86_64 memory-optimized server instance powered by a dedicated AMD EPYC 7763 processor running at 3.525 GHz. It features 20 vCPUs, 10 physical cores, and 160.0 GB of RAM, yielding a high 8.0 GB per vCPU ratio. While it lacks local storage and GPUs, it is Premium Storage capable. Benchmark data reveals strong single-core CPU performance and a top-tier Passmark memory score, alongside average multi-core and memory bandwidth capabilities. The instance excels at small-model LLM text generation but exhibits poor performance on large 70B models. Qualitatively, its high memory density relative to compute cores provides cost-efficient resource allocation for memory-bound tasks. It is best suited for databases, caching layers, and enterprise applications requiring substantial memory without local storage dependencies.

    Workload Profiles

    0.92Score
    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.
