      Server Description

      A dedicated 64-core arm64 compute instance delivering top-tier multi-core performance and high memory bandwidth for parallel workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7g.16xlarge is an arm64 compute-optimized instance powered by 64 dedicated physical cores of the AWS Graviton3 processor running at 2.6 GHz. It features 128.0 GB of RAM, a Nitro hypervisor, and 30 Gbps baseline network bandwidth, with no local storage. The processor includes 32 MB of L3 cache and 1.0 MB of L2 cache per core. Benchmarks indicate top-tier multi-core performance and memory bandwidth, alongside strong software compilation and database operation capabilities. However, single-core performance remains average, and small-model LLM text generation is weak. This instance is qualitatively cost-efficient for highly parallelized workloads, offering high compute density without hyperthreading. It is suited for software compilation, static web serving, database operations, and multi-threaded processing.

      Workload Profiles

      3.37Score
      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.
