    CPU and System Topology

    Server Description

    A dedicated dual-core x86_64 virtual server with NVMe storage, delivering strong single-core performance for lightweight general-purpose workloads.

    General Purpose

    The OVHcloud b3-8 is a general-purpose virtual server featuring 2 dedicated vCPUs on an AMD EPYC x86_64 processor running at 2.3 GHz. It is equipped with 8.0 GB of RAM, 50 GB of local NVMe SSD storage, and operates on the KVM hypervisor. Benchmarks show strong single-core CPU performance, though multi-core execution, memory bandwidth, and database operations generally fall into the average to weak categories. Static web serving throughput is particularly low, placing in the bottom 10 percent. With dedicated CPU allocation and a balanced 1:4 CPU-to-RAM ratio, the b3-8 provides predictable compute resources for its size. It is best suited for lightweight general-purpose applications, single-threaded tasks, text processing, and development environments where consistent, non-burstable CPU performance is required without the need for high-throughput database or web serving capabilities.

    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.
