    Server Description

    An ARM64 compute-optimized platform featuring dedicated Graviton processors, high-speed local NVMe storage, and top-tier multi-core and database performance.

    Compute OptimizedStorage & Database

    Amazon Web Services c8gd.12xlarge is an ARM64 compute-optimized server featuring 48 dedicated physical cores of the AWS Graviton Neoverse-V2 processor running at 2.8 GHz, paired with 96.0 GB of RAM and 2850 GB of local NVMe SSD storage. Operating on the Nitro hypervisor, it delivers 22 Gbps of baseline network bandwidth. Benchmarks indicate top-tier capabilities in memory bandwidth, software compilation, and database operations, alongside strong multi-core processing and static web serving throughput. However, single-core performance and LLM inference tasks fall within the average range. The server lacks x86 instruction sets like AVX-512 and features a relatively low memory-to-core ratio of 2.0 GB. This configuration is highly efficient for multi-threaded workloads, software compilation, database hosting, and high-throughput web serving.

    Workload Profiles

    3.86Score
    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.
