    Server Description

    A memory-optimized x86 platform combining 1.5 TB of DDR5 RAM with 11.4 TB of local NVMe SSD storage for data-intensive workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8id.48xlarge is a memory-optimized instance featuring 192 vCPUs (96 physical cores) powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is equipped with 1536.0 GB of DDR5 memory and 11400 GB of local NVMe SSD storage, managed via the Nitro hypervisor. The system delivers top-tier multi-core CPU performance and memory bandwidth, ranking in the top 10% for database operations, Redis SET throughput, and multi-threaded decompression. While single-core performance remains in the average tier, the inclusion of Intel AMX instructions enables strong CPU-based LLM inference. With a 75 Gbps baseline network bandwidth and massive local storage, this instance is designed for memory-intensive workloads, large-scale databases, and high-throughput data processing.

    Workload Profiles

    9.04Score
    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.
