    Server Description

    A memory-optimized, high-bandwidth instance featuring integrated NVMe storage and robust multi-core performance for demanding database and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5dn.24xlarge is a memory-optimized instance featuring 96 vCPUs and 48 physical cores powered by an Intel Xeon 8259CL processor at 3.1 GHz. It is equipped with 768.0 GB of DDR4 memory, 3600 GB of local NVMe SSD storage, and a 100 Gbps baseline network interface. Operating on the Nitro hypervisor, this instance demonstrates strong multi-core CPU performance and exceptional memory bandwidth, with cached small-block reads reaching 4502.68 GB/sec. It also delivers high throughput for database operations, achieving 75.03 million Redis SET operations per second. While single-core performance is relatively weak, the instance's high memory-to-vCPU ratio and fast local storage make it highly effective for in-memory databases, caching layers, and high-throughput network workloads.

    Workload Profiles

    2.84Score
    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.
