    CPU and System Topology

    Server Description

    A memory-optimized server featuring 1024 GB RAM, dedicated NVMe storage, and strong multi-core performance for database and enterprise workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services x2idn.16xlarge is a memory-optimized server featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8375C processor at 3.5 GHz. It is equipped with 1024.0 GB of DDR4 memory, a bundled 1900 GB NVMe SSD, and a 50 Gbps baseline network interface. Operating on the Nitro hypervisor, this instance delivers strong multi-core CPU performance, database operations, and cryptographic execution, placing in the top 25% of benchmarks. Conversely, single-core performance and memory bandwidth fall into the average tier. This resource profile is optimized for memory-intensive workloads, large databases, and multi-threaded enterprise applications requiring high memory density and fast local storage.

    Workload Profiles

    2.68Score
    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.
