    CPU and System Topology

    Server Description

    A balanced general-purpose server featuring thirty-two dedicated AMD EPYC cores, local NVMe storage, and strong multi-threaded database performance.

    General PurposeStorage & Database

    OVHcloud b3-128 is a General Purpose server powered by an AMD EPYC x86_64 processor with 32 dedicated physical cores running at 2.3 GHz. It features 128 GB of RAM, 400 GB of local NVMe SSD storage, and an 8 Gbps baseline network interface. Operating on a KVM hypervisor, this instance delivers strong multi-core performance, as evidenced by a stress-ng multi-core score of 98377.64 and a Geekbench multi-core score of 17522.0. Memory bandwidth is highly efficient, reaching 4737.01 GB/sec for cached reads. Database operations are a key strength, with Redis SET operations reaching 74.67 million operations per second. This balanced hardware profile provides predictable resource density, making it an excellent fit for database hosting, multi-threaded data processing, software compilation, and general-purpose enterprise applications.

    Workload Profiles

    2.1Score
    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.
