    Server Description

    High-bandwidth memory-optimized instance with local NVMe storage and strong multi-core performance for demanding database and caching workloads.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services r5dn.24xlarge is a memory-optimized instance featuring 96 vCPUs and 48 physical cores powered by an Intel Xeon 8259CL processor running at 3.1 GHz. It is equipped with 768.0 GB of DDR4 memory, 3600 GB of local NVMe SSD storage, and a baseline network bandwidth of 100 Gbps. Operating on the Nitro hypervisor, this instance exhibits a performance profile characterized by strong multi-core CPU capabilities and high memory bandwidth, contrasted with weaker single-core performance. The combination of high memory capacity, fast local storage, and high-speed networking makes this instance qualitatively cost-efficient for memory-intensive and network-bound workloads. It is highly suited for large-scale databases, in-memory data stores like Redis, static web serving, and parallel software compilation.

    Workload Profiles

    2.8Score
    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.
