    CPU and System Topology

    Server Description

    A dedicated 64-core AMD EPYC server with balanced memory and fast NVMe storage for predictable, high-throughput multi-threaded workloads.

    General PurposeCompute Optimized

    OVHcloud b3-256 is a general-purpose server configured with 64 dedicated AMD EPYC physical cores operating at 2.3 GHz on the x86_64 architecture. It features 256.0 GB of RAM, a 400 GB local NVMe SSD, and a 16 Gbps baseline network interface under a KVM hypervisor. Lacking hyperthreading, the instance provides dedicated compute resources per vCPU, resulting in top-tier multi-core CPU performance, software compilation speeds, and Redis transaction throughput. Memory bandwidth is highly efficient, particularly for cached read operations. This balanced resource allocation makes the b3-256 a cost-effective solution for predictable, high-throughput workloads. It is highly suited for multi-threaded data processing, software compilation, database hosting, and high-capacity web serving.

    Workload Profiles

    3.01Score
    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.
