    Server Description

    An ARM64 memory-optimized instance featuring high RAM density and local NVMe storage for memory-intensive databases and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services x2gd.4xlarge is an ARM64 memory-optimized server powered by a 16-core AWS Graviton2 processor running at 2.5 GHz. It features 256.0 GB of RAM, providing a high 16.0 GB per vCPU ratio, and includes 950 GB of local NVMe SSD storage. Operating on the Nitro hypervisor, it delivers 5 Gbps baseline network bandwidth. Benchmarks show average multi-core performance, with a Geekbench multi-core score of 8543.0 and Redis SET operations reaching 18.95 million operations per second. However, single-threaded capabilities are weaker, as evidenced by a Geekbench single-core score of 962.0. Lacking AVX instruction sets, this instance is qualitatively cost-efficient for memory-bound applications. It is best suited for in-memory databases, caching layers, and data processing workloads requiring high memory density and local scratch space.

    Workload Profiles

    0.923Score
    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.
