    CPU and System Topology

    Server Description

    A balanced general-purpose server with dedicated AMD EPYC cores, local NVMe storage, and strong single-core performance for reliable application hosting.

    General PurposeStorage & Database

    The OVHcloud b3-16 is a general-purpose virtual server built on the x86_64 architecture and powered by a dedicated AMD EPYC processor. It features 4 physical cores (1 thread per core) running at 2.3 GHz, paired with 16.0 GB of RAM and 100 GB of local NVMe SSD storage. Operating on a KVM hypervisor, the server provides a baseline network bandwidth of 1 Gbps. Performance benchmarks show strong single-core capabilities, particularly in text processing and single-threaded CPU tasks, while multi-core operations and memory bandwidth remain average. Tradeoffs include lower performance in static web serving and medium LLM prompt processing. This configuration is suitable for general-purpose workloads, application hosting, and database operations requiring dedicated CPU resources without GPU acceleration.

    Workload Profiles

    0.48Score
    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.
