    CPU and System Topology

    Server Description

    A memory-optimized virtual server featuring dedicated AMD EPYC cores and NVMe storage for memory-bound workloads with low parallel processing needs.

    Memory OptimizedGeneral Purpose

    OVHcloud r3-16 is a memory-optimized KVM virtual server featuring 2 dedicated AMD EPYC vCPUs running at 2.3 GHz, 16.0 GB of RAM, and a 50 GB NVMe SSD. Built on the x86_64 architecture, it delivers a high 8.0 GB of memory per core. In benchmarks, the server demonstrates strong single-core CPU performance, ranking in the top 25% for stress-ng single-core tests, though its multi-core performance and memory bandwidth remain average. Tradeoffs include weak multi-core Geekbench scores, low database operation metrics, and a baseline network bandwidth of 0 Gbps. This instance is suited for memory-bound workloads with low parallel processing demands, such as lightweight caching, basic text processing, and small-scale database operations.

    Workload Profiles

    0.28Score
    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.
