    CPU and System Topology

    Server Description

    A compute-optimized platform featuring 160 dedicated physical cores and local NVMe storage for parallel processing workloads.

    Compute OptimizedStorage & Database

    OVHcloud c3-320 is a compute-optimized server instance featuring 160 dedicated physical cores on an AMD EPYC x86_64 architecture running at 2.3 GHz. It is equipped with 320.0 GB of RAM, a 400 GB local NVMe SSD, and a 20 Gbps baseline network bandwidth. Operating under the KVM hypervisor, this instance delivers top-tier multi-core CPU performance, ranking in the top 10% on stress-ng and PassMark benchmarks. It also achieves top-tier results in multi-threaded decompression, software compilation, and Redis SET operations. With a resource density of 2.0 GB of RAM per core, the server is optimized for compute-heavy parallel workloads rather than memory-intensive applications. It is highly suitable for software compilation, ray tracing, static web serving, and database operations.

    Workload Profiles

    4.19Score
    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.
