    Server Description

    An ARM64 compute-optimized instance featuring dedicated Graviton cores, high-speed memory bandwidth, and integrated NVMe local storage.

    Compute OptimizedStorage & Database

    Amazon Web Services c8gd.4xlarge is a compute-optimized, ARM64-based instance powered by 16 dedicated AWS Graviton Neoverse-V2 physical cores running at 2.8 GHz. It features 32.0 GB of system memory, a bundled 950 GB NVMe SSD local instance store, and an 8 Gbps baseline network bandwidth managed by the Nitro hypervisor. Benchmark results show top-tier memory performance with a Passmark memory score of 3138.89, alongside strong uncached memory read bandwidth of 296.81 GB/sec. The instance delivers strong multi-core processing, bzip3 decompression, and database operation performance. With its 1:2 vCPU-to-RAM ratio and high-speed local storage, the c8gd.4xlarge is highly efficient for compute-intensive applications, high-throughput web serving, and local database workloads, though it lacks x86 vector extensions and is less suited for heavy machine learning inference.

    Workload Profiles

    1.76Score
    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.
