    Server Description

    A memory-optimized platform featuring high-density DDR5 RAM, massive local NVMe storage, and advanced matrix extensions for parallelized enterprise workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    Amazon Web Services r8id.32xlarge is a memory-optimized instance featuring 128 vCPUs powered by Intel Xeon 6975P-C processors at 3.9 GHz, 1024.0 GB of DDR5 memory, and 7600 GB of local NVMe SSD storage. Operating on the Nitro hypervisor, it delivers a baseline network bandwidth of 50 Gbps. Benchmark results place this instance in the top tier for multi-core CPU performance, database operations, and memory read bandwidth, though single-core performance remains in the average tier. The processor supports advanced instruction sets like AVX-512 and Intel AMX, enabling top-tier prompt processing speeds for large language models. This hardware profile is designed for memory-intensive databases, Redis caching layers, and parallelized data processing workloads that benefit from high-capacity local storage and dense memory configurations.

    Workload Profiles

    7.4Score
    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.
