      Server Description

      An arm64 compute-optimized instance featuring 64 dedicated cores and 100 Gbps network bandwidth for highly parallel, network-intensive workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6gn.16xlarge is a compute-optimized instance featuring 64 dedicated ARMv8 Neoverse-N1 cores running at 2.5 GHz on an arm64 architecture. It is equipped with 128.0 GB of memory, providing 2.0 GB per core, and operates on the Nitro hypervisor with a baseline network bandwidth of 100 Gbps. The instance lacks local storage and GPU accelerators. Benchmark results show strong multi-core CPU performance, high static web serving throughput, and efficient Redis SET operations, though single-core performance and single-threaded compression tasks are weaker. This profile offers qualitative cost efficiency for highly parallelized, network-intensive workloads. It is suited for multi-threaded applications, software compilation, and high-throughput web serving.

      Workload Profiles

      2.3Score
      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.
