    Server Description

    A memory-optimized instance featuring dedicated Intel Xeon processors and local NVMe SSD storage for memory-intensive database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.4xlarge is a memory-optimized instance featuring 16 vCPUs and 8 physical cores powered by an Intel Xeon 8259CL processor running at 3.1 GHz. Built on the AWS Nitro hypervisor, it delivers 128.0 GB of DDR4 memory alongside 600 GB of local NVMe SSD instance storage. While single-core benchmarks place the instance in the lower 25% performance tier, its multi-core capabilities, memory bandwidth, and database operations consistently rank in the average middle 50% tier. With a baseline network bandwidth of 5 Gbps and no integrated GPUs, this instance is designed for memory-heavy applications, caching layers, and database workloads requiring fast local storage. It offers a balanced resource density for memory-intensive tasks without the premium cost of GPU-accelerated hardware.

    Workload Profiles

    0.73Score
    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.
