    CPU and System Topology

    Server Description

    A memory-optimized platform featuring high-density DDR4 RAM, local NVMe storage, and strong multi-core performance for enterprise database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services x2idn.16xlarge is a memory-optimized server instance designed for memory-intensive enterprise workloads. Powered by an Intel Xeon 8375C processor with 64 vCPUs and 32 physical cores, it features 1024.0 GB of DDR4 RAM and a 1900 GB NVMe SSD instance store. Running on the AWS Nitro hypervisor, the instance delivers a baseline network bandwidth of 50 Gbps. Benchmarks highlight strong multi-core performance, with a Passmark CPU score of 56725.09, and exceptional database operations capabilities scoring 26134.77. While single-core performance is average, its high memory-to-vCPU ratio and fast local storage make it highly efficient for large-scale databases, software compilation, and high-throughput web serving. Additionally, it demonstrates strong text generation speeds in language model inference benchmarks, making it a viable option for CPU-based model execution.

    Workload Profiles

    2.7Score
    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.
