      CPU and System Topology

      Server Description

      An x86_64 virtual machine featuring high memory density and strong memory bandwidth for memory-intensive enterprise workloads without local storage.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E48_v4 is an Ev4-family virtual machine featuring 48 vCPUs and 384.0 GB of RAM on the x86_64 architecture. Powered by an Intel Xeon 8272CL processor running at 2.6 GHz, it provides 24 physical cores with dedicated allocation and no local storage or GPU. Benchmarks indicate strong memory performance, with large-block read-only memory bandwidth reaching 199.45 GB/sec and a strong Passmark memory score. However, single-threaded CPU tasks like gzip compression fall into the bottom 25%. With 8.0 GB of RAM per vCPU, this memory-optimized instance is suited for memory-intensive workloads, including database operations, in-memory caching, and enterprise applications, provided they do not require local storage.

      Workload Profiles

      1.9Score
      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.
