      CPU and System Topology

      Server Description

      A general-purpose virtual machine delivering strong single-core execution and balanced memory allocation for non-parallelized enterprise workloads.

      General Purpose

      Microsoft Azure D4as_v5 is a general-purpose virtual machine powered by an AMD EPYC 7763 processor running at 3.525 GHz on the Microsoft Hyper-V hypervisor. It features 4 dedicated vCPUs across 2 physical cores, 16.0 GB of RAM, and no local storage, though it supports Premium Storage. Benchmarks show a clear performance tradeoff: single-core CPU performance is strong, ranking in the top 25%, while multi-core CPU performance and memory write bandwidth fall into the bottom 25%. Single-threaded compression and image processing tasks perform at average levels, but multi-threaded decompression and database operations are weak. This server is best suited for general-purpose workloads, lightweight web serving, and text processing tasks that rely on single-core execution rather than dense parallel processing or high-throughput local storage.

      Performance

      Workload Profiles

      0.29Score
      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.
