    Server Description

    A memory-optimized instance featuring a high memory-to-vCPU ratio and integrated local NVMe SSD storage for caching and database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.xlarge is a memory-optimized instance featuring 4 vCPUs and 32.0 GB of DDR4 RAM. It is powered by an Intel Xeon 8259CL processor running at 3.1 GHz with 2 physical cores and hyper-threading. The instance includes a bundled 150 GB NVMe SSD local instance store and operates on the AWS Nitro hypervisor with a baseline network bandwidth of 1 Gbps. Benchmark data indicates that while CPU performance and memory bandwidth generally rank in the bottom 25%, the PassMark memory score achieves an average rating in the middle 50%. This hardware profile offers a high memory-to-vCPU ratio of 8 GB per core, making it qualitatively cost-efficient for memory-bound workloads that benefit from local scratch storage. It is suited for small-scale databases, caching layers, and memory-intensive data processing applications that do not require high computational throughput.

    Workload Profiles

    0.25Score
    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.
