      CPU and System Topology

      Server Description

      A single-core virtual machine delivering dedicated high-frequency CPU performance and balanced memory for lightweight, single-threaded workloads.

      General PurposeCompute Optimized

      Microsoft Azure F1as_v7 is a single-core virtual machine from the Fasv7 family, powered by a dedicated 4.5 GHz AMD EPYC 9V45 processor on the x86_64 architecture. It features 1 physical core, 1 thread, and 4.0 GB of RAM, with no local storage or integrated GPU. Benchmarks show top-tier single-core CPU performance, including high-speed single-threaded gzip compression and bzip3 decompression. However, its single-core configuration limits multi-core performance, PassMark scores, and database operations to the bottom 25%. Memory bandwidth is average for large blocks but weak for cached small blocks. This server provides a cost-effective entry point for dedicated compute resources without burstable limitations. It is best suited for lightweight, single-threaded applications, basic web serving, and small-scale language model inference prototyping.

      Workload Profiles

      0.18Score
      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.
