    CPU and System Topology

    Server Description

    A memory-optimized, network-enhanced virtual machine featuring dedicated high-frequency processors and advanced matrix extensions for demanding database and enterprise workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure E48ns_v6 is a memory-optimized virtual machine from the Env6 family, powered by a dedicated 4.2 GHz Intel Xeon 8573C processor with 48 vCPUs and 24 physical cores. It features 384.0 GB of RAM, yielding an 8.0 GB per core memory-to-vCPU ratio, and includes a 260 MB L3 cache with support for AVX-512 and Intel AMX instructions. Running on Microsoft Hyper-V, this network-optimized instance does not include local storage, relying on Premium Storage compatibility. Benchmarks show strong performance in large-block memory bandwidth, database operations, and static web serving throughput, alongside average CPU stress-test results. This server is suited for memory-intensive databases, enterprise applications, and high-throughput web serving workloads.

    Workload Profiles

    2.75Score
    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.
