    Server Description

    A high-bandwidth, memory-optimized virtual server featuring fast local NVMe storage and dedicated Intel Xeon processing for data-intensive enterprise workloads.

    Amazon Web Services r6idn.12xlarge is a memory-optimized instance designed for data-intensive workloads. Powered by a 3.5 GHz Intel Xeon 8375C processor, it provides 48 vCPUs, 384.0 GB of DDR4 RAM, and 2850 GB of local NVMe SSD storage. Operating on the AWS Nitro hypervisor, the instance delivers a baseline network bandwidth of 75 Gbps. Benchmark data indicates strong capabilities in memory-bound and cryptographic tasks, with a Passmark CPU score of 48,727.93 and a Redis SET throughput of 44.3 million operations per second. While the absence of a GPU restricts heavy machine learning training, the high memory-to-core ratio and fast local storage make this instance highly efficient for large databases, real-time analytics, and enterprise-scale web serving.

    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.
