    CPU and System Topology

    Server Description

    A high-density memory-optimized platform featuring dedicated AMD EPYC cores and NVMe storage for demanding in-memory database and caching workloads.

    Memory OptimizedCompute OptimizedStorage & Database

    OVHcloud r3-1024 is a memory-optimized server featuring 128 dedicated AMD EPYC physical cores (128 vCPUs) running at 2.3 GHz on the x86_64 architecture. It is equipped with 1024.0 GB of RAM, 400 GB of NVMe SSD storage, and a 20 Gbps baseline network interface. The server delivers top-tier multi-core CPU and memory bandwidth performance, as evidenced by its top 10% PassMark memory and stress-ng multi-core scores, alongside 166.68 million Redis SET operations per second. While single-core speeds and large-model LLM text generation are moderate, its massive memory footprint and dedicated core allocation make it highly efficient for memory-intensive workloads. It is best suited for in-memory databases, caching layers, and parallel software compilation.

    Workload Profiles

    3.8Score
    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.
