      CPU and System Topology

      Server Description

      A compute-focused virtual machine featuring dedicated AMD EPYC processing power and strong single-core performance for memory-light, CPU-bound workloads.

      Compute Optimized

      The Microsoft Azure F4als_v6 is a compute-focused virtual machine from the Falsv6 family, powered by a dedicated 3.7 GHz AMD EPYC 9V74 processor. Featuring 4 vCPUs and 8.0 GB of RAM, this x86_64 instance is optimized for compute-heavy workloads with low memory requirements. It does not include local storage or GPUs but supports Premium Storage. Benchmarks indicate strong single-core CPU and text processing performance, placing in the top 25%, while multi-core metrics and memory write bandwidth remain average. However, uncached large-block read memory bandwidth is weak, representing a key hardware tradeoff. This instance is qualitatively cost-efficient for single-threaded applications, web serving, and light compilation tasks, but is constrained for memory-intensive workloads.

      Workload Profiles

      0.43Score
      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.
