      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring twenty vCPUs and high memory density for database operations and memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E20_v4 is a memory-optimized virtual machine from the Ev4 family, running on the Microsoft Hyper-V hypervisor. It features a dedicated Intel Xeon 8272CL x86_64 processor with 20 vCPUs (10 physical cores) operating at 2.6 GHz, paired with 160.0 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 accelerators. Benchmarks indicate average performance across most metrics, including a Geekbench multi-core score of 8313.0 and a Redis SET throughput of 16.52 million operations per second. However, single-threaded compression tasks like gzip perform weakly. The E20_v4 is qualitatively cost-efficient for memory-intensive applications, making it appropriate for database operations, software compilation, and static web serving.

      Workload Profiles

      0.89Score
      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.
