      CPU and System Topology

      Server Description

      A dedicated four-core AMD EPYC instance delivering strong single-threaded performance and balanced memory for general-purpose workloads without local storage.

      General Purpose

      Microsoft Azure F4as_v6 is a general-purpose virtual machine featuring 4 dedicated vCPUs on an AMD EPYC 9V74 processor running at 3.7 GHz. It is equipped with 16.0 GB of RAM, 32 MB of L3 cache, and lacks local storage or GPUs. Benchmarks show strong single-core CPU and text processing performance, placing in the top 25%. However, multi-core performance and uncached large-block read memory bandwidth are weaker, with the latter falling into the bottom 25% at 37.88 GB/sec. The instance is suited for single-threaded applications, text processing, and moderate web serving, offering a stable, dedicated hardware profile without hyperthreading overhead. It supports advanced instruction sets like AVX-512 and cryptography acceleration, making it a reliable choice for secure, compute-aligned tasks.

      Workload Profiles

      0.44Score
      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.
