    CPU and System Topology

    Server Description

    A dedicated sixty-four core server with balanced memory and NVMe storage, optimized for highly parallelized multi-threaded workloads and database operations.

    General PurposeCompute Optimized

    The OVHcloud b3-256 is a general-purpose server configured with 64 dedicated AMD EPYC physical cores running at 2.3 GHz on the x86_64 architecture. It features 256.0 GB of RAM (4.0 GB per core), a 400 GB local NVMe SSD, and 16 Gbps baseline network bandwidth. Operating on a KVM hypervisor, the server delivers top-tier multi-core CPU performance, particularly in software compilation, ray tracing, and multi-threaded decompression. Memory bandwidth for cached small blocks also ranks in the top tier, while database operations and static web serving throughput show strong performance. However, single-core benchmarks and LLM text generation speeds are average. This resource profile makes the b3-256 suitable for multi-threaded applications, database hosting, and parallel processing workloads.

    Workload Profiles

    3Score
    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.
