    CPU and System Topology

    Server Description

    A dedicated 32-core AMD EPYC server with NVMe storage, optimized for high-throughput parallel computing and multi-threaded workloads.

    Compute OptimizedStorage & Database

    OVHcloud c3-64 is a compute-optimized server featuring 32 dedicated AMD EPYC physical cores running at 2.3 GHz on the x86_64 architecture. It is equipped with 64.0 GB of RAM, a 400 GB NVMe SSD, and a 4 Gbps baseline network interface. Operating on the KVM hypervisor, the server delivers strong multi-core performance, as evidenced by top 25% scores in multi-core stress-ng, Geekbench, and PassMark CPU benchmarks, alongside a top 10% PassMark memory score. However, single-core performance and single-threaded compression tasks remain in the average tier. With a 2.0 GB per core memory allocation, this server is designed for compute-heavy, parallelized workloads such as software compilation, database operations, Redis caching, and multi-threaded data processing, offering a balanced, high-density compute profile without the overhead of excess memory.

    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.
