    CPU and System Topology

    Server Description

    A dedicated sixty-four core compute instance designed for highly parallelized workloads, multi-threaded software compilation, and high-throughput caching.

    Compute OptimizedStorage & Database

    OVHcloud c3-128 is a compute-optimized server featuring 64 dedicated physical cores on an AMD EPYC x86_64 processor running at 2.3 GHz with no hyperthreading. It is equipped with 128 GB of RAM, a 400 GB NVMe SSD, and an 8 Gbps baseline network interface. Benchmark results indicate top-tier multi-core CPU performance, software compilation speeds, and Redis SET throughput, alongside strong database and static web serving capabilities. Conversely, single-threaded performance and LLM text generation speeds fall into the average range. With a low memory-to-core ratio of 2.0 GB per core, this instance represents a tradeoff favoring dense parallel processing over memory-intensive operations. It is suited for multi-threaded workloads such as software compilation, ray tracing, image processing, and high-throughput caching.

    Workload Profiles

    3.15Score
    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.
