    Server Description

    A memory-optimized instance combining high-speed DDR5 RAM, local NVMe SSD storage, and advanced Intel Xeon processing for data-intensive workloads.

    Memory OptimizedStorage & Database

    The Amazon Web Services r8id.12xlarge is a memory-optimized instance featuring 48 vCPUs, 24 physical cores, and 384.0 GB of high-speed DDR5 memory. Powered by an Intel Xeon 6975P-C processor running at 3.9 GHz, this instance integrates 2850 GB of local NVMe SSD storage and operates on the Nitro hypervisor with a 22 Gbps baseline network bandwidth. Benchmark results show strong performance, with memory read-only bandwidth reaching 3840.86 GB/sec and Redis SET operations exceeding 85 million operations per second. The CPU supports advanced instruction sets, including AVX-512 and AMX, which accelerate vector and matrix operations. This server is optimized for memory-intensive and storage-heavy workloads, making it highly suitable for enterprise database hosting, in-memory caching, and data processing pipelines.

    Workload Profiles

    3.64Score
    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.
