      CPU and System Topology

      Server Description

      An arm64 compute-optimized server featuring dedicated ARMv9 cores and top-tier memory bandwidth for data-intensive workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8g.4xlarge is a compute-optimized instance featuring 16 dedicated arm64 physical cores on the ARMv9 Neoverse-V2 architecture running at 2.8 GHz. It is configured with 32.0 GB of memory, providing 2.0 GB per core, and operates on the Nitro hypervisor with an 8 Gbps baseline network bandwidth. The instance does not include local storage or GPUs. Benchmarks highlight top-tier memory performance, with a Passmark memory score in the top 10% and strong large-block memory bandwidth reads of 302.31 GB/sec. While CPU performance in stress-ng and Geekbench is average, multi-threaded bzip3 decompression and database operations perform strongly. This server is highly efficient for memory-bandwidth-sensitive compute tasks, multi-threaded decompression, database operations, and static web serving.

      Workload Profiles

      1.7Score
      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.
