      Server Description

      A high-bandwidth, 64-core ARM64 compute instance optimized for parallel processing, distributed databases, and high-throughput network workloads without local storage.

      Compute Optimized

      Amazon Web Services c8gn.16xlarge is a compute-optimized instance featuring 64 dedicated ARMv9 Neoverse-V2 physical cores running at 2.8 GHz. Built on the Nitro hypervisor, it includes 128 GB of RAM and a high-speed 200 Gbps baseline network interface, though it lacks local storage and GPU accelerators. Benchmark results highlight top-tier multi-core CPU performance, exceptional memory bandwidth, and high-throughput database capabilities, as demonstrated by 144.9 million Redis SET operations per second and 116.84 GB/sec static web serving. However, single-core performance and small-model LLM text generation are more modest. This profile offers strong qualitative cost efficiency for highly parallelized, network-heavy workloads. It is highly suited for distributed databases, software compilation, static web serving, and multi-threaded data processing.

      Workload Profiles

      4.91Score
      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.
