    Server Description

    An x86 memory-optimized platform combining dedicated Intel Xeon processing, high-speed DDR5 memory, and integrated local NVMe SSD storage.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services r8id.8xlarge is a memory-optimized instance featuring 32 vCPUs and 16 physical cores powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is configured with 256.0 GB of DDR5 memory and a bundled 1900 GB NVMe SSD local instance store. Operating on the Nitro hypervisor, the server delivers a baseline network bandwidth of 15 Gbps. Benchmark results show strong CPU capabilities, with a Passmark CPU score of 51,704.46 and top-tier text processing performance. While it handles small-scale language model inference efficiently, text generation for large 70B models is a relative bottleneck. This hardware configuration is designed for memory-intensive databases, Redis caching layers, and high-throughput web serving.

    Workload Profiles

    2.74Score
    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.
