    Server Description

    A memory-optimized platform featuring dedicated Intel Xeon processors and high-speed local NVMe storage for memory-intensive database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.4xlarge is a memory-optimized instance featuring 16 vCPUs, 8 physical Intel Xeon 8259CL cores, and 128.0 GB of DDR4 RAM. Operating on the Nitro hypervisor, this x86_64 platform includes 600 GB of local NVMe SSD storage and a baseline network bandwidth of 5 Gbps. Benchmark data reveals a performance tradeoff: single-core CPU execution and single-threaded compression tasks rank in the bottom 25%, while multi-core operations, memory bandwidth, and Redis SET operations perform in the average middle 50% tier. This resource profile makes the instance qualitatively cost-efficient for memory-heavy applications requiring high-speed local storage, such as database servers and caching layers, though it is less suited for single-threaded compute-bound workloads.

    Workload Profiles

    0.757Score
    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.
