    CPU and System Topology

    Server Description

    A high-density memory-optimized instance featuring dedicated AMD EPYC cores and top-tier multi-core performance for memory-bound enterprise workloads.

    Memory OptimizedCompute OptimizedStorage & Database

    OVHcloud r3-512 is a memory-optimized server instance running on the KVM hypervisor. It is equipped with 64 dedicated AMD EPYC physical cores on the x86_64 architecture, operating at 2.3 GHz with one thread per core. The hardware configuration includes 512.0 GB of RAM, a 400 GB NVMe SSD, and 20 Gbps baseline network bandwidth. Benchmark data places the instance in the top 10% for multi-core processing, Passmark memory scores, and Redis SET operations, though single-threaded compression tasks perform at an average level. The high memory-to-core ratio provides qualitative cost efficiency for memory-intensive deployments, offset by a relatively small local storage capacity. This server is suited for in-memory databases, large-scale caching, multi-threaded compilation, and data-intensive enterprise workloads.

    Workload Profiles

    3.15Score
    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.
