    CPU and System Topology

    Server Description

    A memory-optimized server featuring an ultra-high RAM-to-vCPU ratio and local NVMe storage for memory-bound enterprise workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services x2iedn.4xlarge is a memory-optimized instance featuring 16 vCPUs and 8 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is equipped with 512.0 GB of DDR4 RAM, providing a high memory-to-core ratio of 32.0 GB per core, alongside a 475 GB local NVMe SSD. Operating on the Nitro hypervisor, the instance delivers a baseline network bandwidth of 12 Gbps. Benchmark results show average tier performance, including a Passmark CPU score of 20852.39 and 15.66 million Redis SET operations per second. However, large language model prompt processing drops to a weak tier of 31.41 tokens/sec for 7B models. This hardware profile is suited for memory-intensive databases, in-memory caching, and data processing workloads.

    Workload Profiles

    1.04Score
    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.
