      CPU and System Topology

      Server Description

      A dedicated four-core virtual machine delivering exceptional single-core clock speeds and balanced memory for predictable compute workloads.

      General PurposeCompute Optimized

      Microsoft Azure F4as_v7 is a general-purpose virtual machine from the Fasv7 family, featuring 4 dedicated vCPUs on an AMD EPYC 9V45 processor running at 4.5 GHz. Built on the x86_64 architecture with 16.0 GB of RAM, this instance lacks bundled local storage and GPUs but supports Premium Storage. It delivers top-tier single-core performance, with stress-ng single-core and single-threaded compression benchmarks placing in the top 10%. Multi-core and memory bandwidth metrics remain in the average tier. The dedicated, non-hyperthreaded cores provide predictable performance, making it highly cost-efficient for single-threaded workloads, database operations, and small-scale LLM text generation.

      Performance

      Workload Profiles

      0.46Score
      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.
