    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring dedicated Intel Xeon processing and advanced matrix extensions for network-intensive workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure E4ns_v6 is a network-optimized virtual machine from the Env6 family, featuring 4 vCPUs and 32.0 GB of RAM. Powered by a dedicated Intel Xeon 8573C processor running at 4.2 GHz, it utilizes 2 physical cores with hyper-threading and a large 260 MB L3 cache. The architecture supports Intel Advanced Matrix Extensions and AVX-512. While single-core performance is solid, with strong single-threaded gzip compression, multi-core and memory bandwidth benchmarks are relatively weak. The instance lacks local storage, relying instead on Premium Storage capabilities. It is best suited for memory-intensive, network-oriented workloads, moderate database caching, and light web serving.

    Workload Profiles

    0.449Score
    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.
