    Server Description

    A memory-optimized x86 platform featuring high-speed DDR5 RAM, integrated NVMe instance storage, and strong single-core processing capabilities.

    Memory OptimizedStorage & Database

    Amazon Web Services r8id.4xlarge is a memory-optimized instance featuring 16 vCPUs and 8 physical cores powered by a 3.9 GHz Intel Xeon 6975P-C processor. It is configured with 128.0 GB of high-speed 7 GHz DDR5 memory and 950 GB of local NVMe SSD instance storage. Operating on the Nitro hypervisor, this instance delivers top-tier single-core CPU and text processing performance in benchmark evaluations, alongside strong single-threaded compression speeds. The hardware includes Intel Advanced Matrix Extensions (AMX) and Advanced Vector Extensions (AVX-512), which facilitate efficient local data processing and small-scale model inference. The high memory-to-vCPU ratio and integrated local NVMe storage make this instance highly efficient for memory-bound applications, database hosting, and text-heavy processing workloads.

    Workload Profiles

    1.61Score
    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.
