    Server Description

    A high-capacity memory-optimized platform featuring massive local NVMe storage and advanced matrix acceleration for demanding database and data processing workloads.

    Memory OptimizedStorage & Database

    The Amazon Web Services r8id.32xlarge is a memory-optimized server instance powered by dedicated Intel Xeon 6975P-C processors with 128 vCPUs (64 physical cores) running at 3.9 GHz. It features 1024.0 GB of DDR5 memory and 7600 GB of local NVMe SSD storage, operating on the AWS Nitro hypervisor with 50 Gbps baseline network bandwidth. The CPU architecture supports AVX-512 and Intel AMX instructions, enabling accelerated matrix and cryptographic operations. Benchmark data shows top-tier multi-core CPU, database, and memory read performance, though single-core performance remains average. This instance is highly suited for memory-intensive and storage-heavy workloads, such as large-scale databases, Redis caching, and CPU-based machine learning inference.

    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.
