      CPU and System Topology

      Server Description

      A memory-optimized virtual machine featuring high single-core AMD EPYC performance and a dense memory-to-vCPU ratio for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E4as_v7 is a memory-optimized virtual machine from the Easv7 family, powered by a 4.5 GHz AMD EPYC 9V45 processor. It provides 4 dedicated vCPUs (2 physical cores with multithreading) and 32.0 GB of RAM, establishing a high memory-to-vCPU ratio of 8.0 GB per vCPU. Running on the Microsoft Hyper-V hypervisor, this x86_64 instance lacks local storage and GPUs but supports Premium Storage. Benchmarks show top-tier single-core CPU performance and single-threaded compression, though multi-core scaling and memory bandwidth remain average. Database operations and multi-threaded decompression are relatively weak. This server is best suited for memory-bound workloads, Redis caching, and static web serving, where high memory capacity is required but massive parallel compute or local storage is not.

      Workload Profiles

      0.4Score
      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.
