    Server Description

    An isolated, high-capacity memory-optimized server featuring 104 dedicated Intel Xeon vCPUs for demanding multi-threaded enterprise workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure E104i_v5 is an isolated, memory-optimized server in the EIv5 family, powered by an Intel Xeon 8370C processor. It features 104 dedicated vCPUs across 52 physical cores, 672.0 GB of RAM, and no local storage. Operating on the x86_64 architecture, it delivers strong multi-core performance, highlighted by a PassMark CPU score of 79,491.91 and a multi-threaded bzip3 decompression speed of 470.08 GB/sec. Cryptographic performance is in the top 10% tier, though single-core benchmarks and large-scale LLM text generation are average to weak. This configuration is suited for memory-intensive databases, enterprise web serving, and concurrent software compilation.

    Workload Profiles

    4.16Score
    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.
