    Server Description

    An ARM-based storage-optimized instance featuring high-capacity local NVMe SSD storage and balanced memory for data-intensive workloads.

    Storage & DatabaseGeneral Purpose

    Amazon Web Services is4gen.2xlarge is a storage-optimized instance featuring an 8-core AWS Graviton Neoverse-N1 ARM64 processor running at 2.5 GHz on the Nitro hypervisor. It is equipped with 48.0 GB of system memory and a 7500 GB local NVMe SSD. The instance delivers average multi-core CPU performance, with a stress-ng multi-core score of 12134.02, and average database performance, processing 9.55 million Redis SET operations per second. However, single-core capabilities are weaker, with a Geekbench single-core score of 950.0 and lower performance in compression tasks. Lacking advanced vector extensions like AVX or AMX, it is not designed for heavy mathematical acceleration or complex LLM inference. Instead, its high local storage density and balanced memory profile make it qualitatively cost-efficient for storage-intensive applications, database hosting, and static web serving.

    Workload Profiles

    0.57Score
    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.
