    CPU and System Topology

    Server Description

    A high-density compute platform featuring one hundred sixty dedicated physical cores and local NVMe storage for parallelized enterprise workloads.

    Compute OptimizedStorage & Database

    OVHcloud c3-320 is a compute-optimized server featuring 160 dedicated physical AMD EPYC cores on the x86_64 architecture, running at 2.3 GHz with no hyperthreading. It is equipped with 320 GB of RAM, a 400 GB NVMe SSD, and a 20 Gbps baseline network interface. Benchmark results show top-tier multi-core CPU performance, software compilation speeds, and memory bandwidth, alongside strong static web serving and database capabilities. The dedicated core allocation and 2.0 GB of RAM per core profile deliver high compute density for parallel processing. This server is designed for demanding workloads such as software compilation, multi-threaded data decompression, ray tracing, and high-throughput database operations.

    Workload Profiles

    4.16Score
    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.
