      CPU and System Topology

      Server Description

      A balanced general-purpose virtual machine delivering top-tier single-core AMD EPYC performance and dedicated resources for diverse workloads.

      General Purpose

      The Microsoft Azure D4as_v7 is a general-purpose virtual machine from the Dasv7 family, powered by an AMD EPYC 9V45 processor running at 4.5 GHz. Utilizing the x86_64 architecture, it provides 4 dedicated vCPUs and 16.0 GB of RAM, yielding a balanced 4.0 GB per core ratio. This instance does not include local storage but supports Premium Storage. Benchmarks reveal top-tier single-core CPU performance, single-threaded text processing, and compression, while multi-core operations, memory bandwidth, and database operations perform in the average tier. Conversely, multi-threaded decompression and medium-model LLM prompt processing show weaker results. The D4as_v7 is highly suitable for general-purpose workloads, including web serving, software compilation, and text processing tasks that benefit from strong single-threaded performance.

      Workload Profiles

      0.41Score
      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.
