    Server Description

    A high-capacity compute and storage platform featuring dedicated Intel Xeon processors, massive NVMe SSD capacity, and high-speed networking.

    Compute OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services trn1.32xlarge is a high-capacity compute instance built on the Nitro hypervisor. It features 128 dedicated vCPUs from Intel Xeon 8375C processors running at 3.5 GHz, paired with 512.0 GB of DDR4 memory and 7600 GB of local NVMe SSD storage. The server delivers a baseline network bandwidth of 100 Gbps. Benchmark results show top-tier multi-core CPU performance, with a Passmark CPU score of 86301.41, and strong memory read bandwidth of up to 6667.57 GB/sec. It is highly efficient for database operations, showing strong Redis SET performance of 103.85 million operations per second, and excels in static web serving. While prompt processing for medium LLM models is strong, text generation for large 70B models represents a performance tradeoff. This instance is suited for multi-threaded CPU tasks, database hosting, and high-throughput web serving.

    Workload Profiles

    4.42Score
    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.
