    Server Description

    A memory-optimized instance featuring high-capacity DDR4 RAM and integrated local NVMe SSD storage for demanding database and data processing workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.12xlarge is a memory-optimized instance featuring 48 vCPUs and 24 physical cores powered by an Intel Xeon 8259CL processor running at 3.1 GHz. It is equipped with 384.0 GB of DDR4 memory and 1800 GB of local NVMe SSD storage, operating on the Nitro hypervisor with a 12 Gbps baseline network bandwidth. Performance benchmarks show average multi-core CPU capabilities and memory bandwidth, though single-core performance is relatively weak. The combination of high memory capacity and fast local NVMe storage makes this instance highly suitable for memory-intensive workloads, database operations, and data processing tasks that require substantial temporary storage.

    Workload Profiles

    1.6Score
    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.
