      CPU and System Topology

      Server Description

      A burstable, Intel-powered virtual machine offering balanced memory and average single-core performance for workloads with variable CPU utilization.

      Burstable & BudgetGeneral Purpose

      Microsoft Azure B4s_v2 is a burstable virtual machine from the Bsv2 family, running on the Microsoft Hyper-V hypervisor. It is powered by an Intel Xeon 8370C x86_64 processor operating at 2.8 GHz, featuring 4 vCPUs across 2 physical cores and 16.0 GB of RAM. The hardware lacks local storage and dedicated GPUs but supports Premium Storage. Performance benchmarks indicate average single-core capabilities, as seen in Geekbench single-core and Passmark CPU encryption tests, while multi-core and memory bandwidth metrics generally fall into the weak category. The burstable CPU allocation model provides a cost-effective option for workloads with fluctuating resource demands. This server is suited for static web serving, software development, and lightweight database tasks that do not require sustained, high-intensity multi-core processing.

      Workload Profiles

      0.37Score
      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.
