      CPU and System Topology

      Server Description

      A burstable, cost-efficient virtual machine featuring strong single-core performance and 8 GB of memory for variable, lightweight workloads.

      Microsoft Azure B4als_v2 is a burstable virtual machine from the Basv2 family, featuring an AMD EPYC 7763 processor with 4 vCPUs across 2 physical cores, running at 3.525 GHz on an x86_64 architecture. It is configured with 8.0 GB of RAM, lacks local storage, and has no GPU. Performance benchmarks reveal a strong single-core CPU capability, ranking in the top 25% on stress-ng, but multi-core and memory performance are weak, falling into the bottom 25% and 10% respectively. This resource profile makes the server a cost-efficient option for workloads with variable CPU utilization. It is best suited for lightweight applications, development environments, and low-traffic web serving.

      Workload Profiles

      0.27Score
      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.
