    Server Description

    A memory-optimized instance combining dedicated Intel Xeon processors with high-capacity local NVMe SSD storage for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6id.12xlarge is a memory-optimized instance featuring 48 vCPUs and 24 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the Nitro hypervisor, it delivers 384.0 GB of DDR4 memory alongside 2850 GB of local NVMe SSD instance storage and 19 Gbps baseline network bandwidth. Benchmark results show a stress-ng multi-core score of 46468.49 and a Passmark CPU encryption score of 43337.66, indicating strong cryptographic performance. The instance is highly efficient for workloads requiring a balance of large memory capacity and fast local storage, such as high-performance databases, in-memory caches, and data-intensive enterprise applications.

    Workload Profiles

    2.3Score
    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.
