      CPU and System Topology

      Server Description

      An x86_64 memory-optimized virtual machine featuring a high memory-to-core ratio for memory-intensive workloads with moderate processing demands.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E4s_v5 is an x86_64 memory-optimized virtual machine within the ESv5 family, running on the Microsoft Hyper-V hypervisor. It features 4 dedicated vCPUs from 2 physical Intel Xeon 8370C cores clocked at 2.8 GHz, paired with 32.0 GB of RAM. This configuration provides a high memory-to-vCPU ratio of 8.0 GB per core, though it lacks local storage and GPU resources. Performance benchmarks indicate average single-core capabilities, with a Geekbench single-core score of 1664.0, but show weak multi-core scaling and memory bandwidth, as evidenced by a multi-core Geekbench score of 3527.0 and large-block read speeds of 29.84 GB/sec. This server is qualitatively cost-efficient for memory-heavy, low-compute workloads. It is best suited for memory-bound applications, static web serving, and moderate database operations that do not demand high parallel processing power.

      Workload Profiles

      0.36Score
      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.
