      CPU and System Topology

      Server Description

      A dedicated sixty-four core ARMv9 compute instance delivering exceptional memory bandwidth and multi-threaded performance for demanding scale-out workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8g.16xlarge is a compute-optimized server instance built on the arm64 architecture and powered by 64 dedicated AWS Neoverse-V2 physical cores running at 2.8 GHz. Operating on the Nitro hypervisor, it features 128.0 GB of system memory and a 30 Gbps baseline network bandwidth, with no bundled local storage or GPU accelerators. Benchmark data highlights top-tier performance in multi-core processing, software compilation, and memory bandwidth, alongside exceptional throughput in static web serving and Redis operations. The custom ARM-based hardware profile delivers high resource density and compute efficiency. This instance is highly suited for compute-intensive workloads, including software compilation, database operations, high-throughput 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.
