    CPU and System Topology

    Server Description

    A high-memory server with dedicated AMD EPYC processing and local NVMe storage for memory-intensive database and caching workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E16-4ads_v7 is an x86_64 memory-optimized server featuring 4 dedicated vCPUs from 2 physical AMD EPYC 9V45 cores running at 4.5 GHz. It is equipped with 128.0 GB of RAM, providing a high ratio of 32.0 GB per core, and includes a 945 GB local NVMe SSD. Performance benchmarks show top-tier single-core CPU execution and single-threaded compression speeds, though multi-threaded performance scales moderately, with multi-core stress-ng and PassMark scores landing in the average tier. The server delivers average memory bandwidth and handles Redis SET operations at 7.7 million operations per second. This hardware profile is highly suited for memory-intensive workloads, relational databases, and caching systems that benefit from high memory capacity and fast local storage without requiring massive parallel compute resources.

    Workload Profiles

    0.42Score
    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.
