    CPU and System Topology

    Server Description

    A memory-optimized virtual machine featuring high memory bandwidth and dedicated Intel Xeon processors for memory-intensive enterprise workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure E48_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 48 dedicated vCPUs, 24 physical cores, and 384.0 GB of RAM, yielding a high 1:8 memory-to-vCPU ratio. The server does not include local storage or GPU accelerators. Performance testing highlights strong memory capabilities, with uncached large-block read and write bandwidths ranking in the top 25 percent, alongside strong multi-threaded bzip3 decompression. Conversely, single-threaded compression and large-model LLM inference represent performance tradeoffs, scoring in the bottom 25 percent. This server is qualitatively cost-effective for memory-intensive workloads that rely on network-attached storage. It is best suited for relational databases, in-memory caches, and multi-threaded data processing.

    Workload Profiles

    1.87Score
    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.
