    CPU and System Topology

    Server Description

    A dedicated dual-core AMD EPYC virtual server with NVMe storage, optimized for single-threaded compute tasks and lightweight utility workloads.

    Compute Optimized

    The OVHcloud c3-4 is a compute-optimized virtual server powered by an x86_64 AMD EPYC processor with 2 dedicated physical cores and 2 vCPUs running at 2.3 GHz. It is equipped with 4.0 GB of RAM and a 50 GB NVMe SSD for local storage. Operating on the KVM hypervisor, this instance delivers strong single-core CPU performance, though its multi-core capabilities and memory bandwidth are more modest. The server lacks GPU acceleration and is designed for workloads that prioritize dedicated CPU execution over high memory capacity. It is qualitatively cost-efficient for lightweight compute tasks, making it suitable for single-threaded applications, basic text processing, and small-scale utility workloads.

    Performance

    Workload Profiles

    0.26Score
    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.
