    Server Description

    A memory-optimized virtual machine featuring dedicated AMD processors, high memory density, and fast local SSD storage for enterprise workloads.

    Microsoft Azure EC20ads_v5 is an x86_64 memory-optimized virtual machine instance from the ECADSv5 family, running on the Microsoft Hyper-V hypervisor. It is equipped with 20 dedicated vCPUs and 160.0 GB of system memory, establishing a high memory-to-vCPU ratio of 8.0 GB per core. The hardware configuration includes a bundled 768 GB local SSD and supports Premium Storage for high-performance external disk attachments. This instance does not feature an integrated GPU or include complimentary public IPv4 addresses. With its high memory density, dedicated compute resources, and fast local storage, the EC20ads_v5 is designed for memory-intensive enterprise applications, relational database hosting, and caching layers that require significant RAM and low-latency local storage.

    Workload Profiles

    0.73Score
    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.Partial coverage: missing component benchmark(s): Memory bandwidth (read, 16 MB ~ L3).
