      CPU and System Topology

      Server Description

      A burstable ARM64 virtual machine offering balanced memory and variable CPU performance for cost-conscious development and light web serving workloads.

      Burstable & BudgetGeneral Purpose

      Microsoft Azure B4ps_v2 is a burstable virtual machine from the Bpsv2 family, utilizing an ARM64 architecture. Powered by an Ampere ARMv8 Neoverse-N1 processor running at 3.0 GHz, it features 4 physical cores, 4 vCPUs, and 16.0 GB of RAM, providing a balanced 4.0 GB of memory per core. The instance lacks bundled local storage and GPU accelerators but is Premium Storage capable. Benchmark data shows average CPU performance, with a stress-ng multi-core score of 7252.95, alongside average large-block memory write bandwidth of 29.04 GB/sec. However, it exhibits weaker performance in cryptographic and intensive computing tasks, such as a Passmark encryption score of 647.61. This server is qualitatively cost-efficient for workloads with variable CPU demands, making it suitable for static web serving, lightweight database operations, and development environments.

      Workload Profiles

      0.34Score
      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.
