      Server Description

      A high-bandwidth, 64-core ARM64 compute instance designed for network-intensive workloads, software compilation, and distributed multi-threaded applications.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7gn.16xlarge is a compute-optimized instance powered by a 64-core AWS Graviton3 Neoverse-V1 ARM64 processor running at 2.6 GHz. It features 128.0 GB of memory, providing 2.0 GB per core, and lacks local storage and GPUs. The instance delivers a baseline network bandwidth of 200 Gbps. In benchmark evaluations, the c7gn.16xlarge demonstrates top-tier performance in software compilation and multi-core Geekbench tests, alongside strong memory bandwidth and database operations. However, single-core performance remains average, and small-model LLM text generation is poor. This server offers high resource density and qualitative cost efficiency for multi-threaded, network-heavy workloads. It is best suited for network-intensive applications, software compilation, and distributed databases.

      Workload Profiles

      3.36Score
      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.
