      CPU and System Topology

      Server Description

      A memory-optimized, network-ready virtual server featuring dedicated Intel Xeon processors and high memory-to-core density for specialized workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E4ns_v6 is an Env6-family, memory-optimized server featuring 4 dedicated vCPUs and 32.0 GB of RAM. Powered by an Intel Xeon 8573C x86_64 processor running at 4.2 GHz under Microsoft Hyper-V, it includes 2 physical cores, 2 threads per core, and a 260 MB L3 cache. The hardware supports AVX-512 and AMX instructions but lacks local storage and GPUs. Benchmarks indicate average single-core CPU performance (1916.18 stress-ng) and average static web serving (7.48 GB/sec), though multi-core performance and memory bandwidth are weak. Qualitatively, it provides high memory density per vCPU on dedicated Intel silicon. It is best suited for memory-intensive workloads, caching layers, and network-optimized tasks that do not demand intensive multi-threaded compute.

      Workload Profiles

      0.45Score
      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.
