    Server Description

    High-density ARM architecture featuring 64 physical cores, 128 GB memory, and direct-attached local NVMe storage for data-intensive parallel workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c8gd.16xlarge is a compute-optimized instance featuring 64 physical ARMv9 Graviton Neoverse-V2 cores operating at 2.8 GHz. It includes 128 GB of main memory, 3,800 GB of direct-attached local NVMe SSD storage, and 30 Gbps baseline network bandwidth running on the AWS Nitro hypervisor. Benchmark data indicates strong multi-core scaling and memory throughput, recording 459.25 GB/sec uncached memory read speeds and 133.11 million operations per second in Redis SET evaluations. While single-threaded processing scores in average ranges, the dedicated core architecture and integrated local storage offer sustained throughput for resource-dense parallel workloads. The server is well suited for database operations, key-value caching layers, multi-threaded software build automation, static web distribution, and parallel data processing jobs.

    Workload Profiles

    4.8Score
    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.
