      Server Description

      An ARM64 compute-optimized server featuring sixty-four dedicated physical cores and high multi-threaded throughput for parallelized workloads and web serving.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6g.16xlarge is a compute-optimized instance featuring 64 dedicated ARMv8 Neoverse-N1 physical cores running at 2.5 GHz, paired with 128.0 GB of memory. Operating on the Nitro hypervisor, this server provides a 25 Gbps baseline network bandwidth but lacks local storage and GPU accelerators. Benchmark results indicate strong multi-core performance, highlighted by high software compilation speeds, a stress-ng multi-core score of 97056.55, and static web serving throughput of 45.55 GB/sec. However, single-core performance is a notable tradeoff, with weak single-threaded decompression and a Geekbench single-core score of 970.0. The instance is suited for highly parallelized workloads, including static web serving, Redis databases, and multi-threaded software compilation, offering a high density of dedicated physical cores for parallel processing tasks.

      Workload Profiles

      2.4Score
      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.
