    CPU and System Topology

    Server Description

    An x86_64 memory-optimized virtual machine featuring a high memory-to-core ratio for database operations and in-memory caching workloads.

    Memory OptimizedGeneral Purpose

    The Microsoft Azure E20_v4 is an x86_64 memory-optimized virtual machine from the Ev4 family, powered by a 2.6 GHz Intel Xeon 8272CL processor. It features 20 dedicated vCPUs and 160.0 GB of RAM, providing a high 8.0 GB of memory per core. This instance does not include local storage or GPU accelerators. Benchmark results place the server in the average tier for most operations, with a multi-core Geekbench score of 8313.0 and Redis SET performance of 16.52 million operations per second. However, single-threaded bzip3 decompression and medium-model LLM prompt processing represent performance bottlenecks, scoring in the bottom 25% tier. The E20_v4 is suited for memory-intensive applications, database operations, and caching workloads that do not require local NVMe storage or specialized GPU acceleration.

    Workload Profiles

    0.888Score
    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.
