      CPU and System Topology

      Server Description

      An AMD-powered virtual machine offering high memory density and strong single-core performance for memory-intensive enterprise workloads without local storage.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E48as_v7 is an x86_64 virtual machine from the Easv7 family, powered by a 4.5 GHz AMD EPYC 9V45 processor. It features 48 dedicated vCPUs, 24 physical cores, and 384.0 GB of RAM, establishing a high 8.0 GB per vCPU memory ratio. The instance lacks local storage and GPUs, relying on remote Premium Storage. Benchmarks show top 10% single-core CPU and compression performance, alongside top 25% multi-core and database execution speeds. However, uncached large-block memory read bandwidth remains in the middle 50%. This configuration provides qualitative cost efficiency for memory-heavy workloads by avoiding the premium of local NVMe or GPU hardware. It is suited for database operations, in-memory caching, and general-purpose enterprise applications.

      Workload Profiles

      2.3Score
      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.
