    CPU and System Topology

    Server Description

    A dedicated 32-core compute instance with NVMe storage, delivering strong multi-core processing and high-speed memory performance for parallel workloads.

    Compute OptimizedStorage & Database

    OVHcloud c3-64 is a compute-optimized server instance configured with 32 dedicated AMD EPYC physical cores and 32 vCPUs on the x86_64 architecture. It features 64.0 GB of RAM, a 400 GB NVMe SSD, and a 4 Gbps baseline network bandwidth. Operating on the KVM hypervisor, this instance delivers strong multi-core performance, ranking in the top 25% for stress-ng and Passmark CPU benchmarks. Memory performance is exceptionally strong, placing in the top 10% on Passmark memory tests. With a resource ratio of 2.0 GB of RAM per core and no hyperthreading, the c3-64 offers high cost efficiency for compute-heavy workloads that require dedicated execution resources without massive memory footprints. It is highly suitable for software compilation, database operations, ray tracing, and small-scale language model inference.

    Workload Profiles

    2.16Score
    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.
