    CPU and System Topology

    Server Description

    A memory-optimized instance featuring dedicated AMD EPYC cores, high-capacity RAM, and local NVMe storage for demanding database workloads.

    Memory OptimizedCompute OptimizedStorage & Database

    OVHcloud r3-512 is a memory-optimized server instance featuring 64 dedicated physical cores on an AMD EPYC x86_64 processor running at 2.3 GHz. It is equipped with 512.0 GB of RAM, providing 8.0 GB of memory per core, and includes 400 GB of local NVMe SSD storage. Operating on the KVM hypervisor, the instance delivers 20 Gbps baseline network bandwidth. Benchmarks highlight top-tier multi-core and memory performance, with a PassMark CPU score of 94,314.31 and Redis SET operations reaching 134.58 million per second. While single-core performance is moderate, the high memory density and dedicated physical cores make this instance highly efficient for memory-intensive workloads, large-scale database operations, and multi-threaded software compilation.

    Workload Profiles

    3.1Score
    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.
