    CPU and System Topology

    Server Description

    A dedicated AMD EPYC server featuring balanced memory-to-core allocation and high-speed local NVMe storage for general-purpose workloads.

    General PurposeStorage & Database

    The OVHcloud b3-64 is a general-purpose server featuring 16 dedicated AMD EPYC physical cores on the x86_64 architecture, running at 2.3 GHz with a 1:1 vCPU-to-core ratio. Equipped with 64.0 GB of RAM and a 400 GB NVMe SSD, it delivers a balanced hardware profile. Benchmarks indicate strong single-core CPU performance and high memory bandwidth for large-block operations, alongside average multi-core and database execution speeds. The network interface provides a baseline bandwidth of 4 Gbps, and the server includes one public IPv4 address. Lacking GPU acceleration and AVX-512 support, the b3-64 is optimized for workloads requiring dedicated CPU resources, such as database hosting, web serving, and general-purpose application deployments.

    Workload Profiles

    1.3Score
    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.
