      Server Description

      A dedicated 32-core ARM64 compute-optimized server delivering top-tier memory bandwidth and high-speed network performance for multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8gb.8xlarge is a compute-optimized server featuring 32 dedicated physical cores powered by the ARMv9 AWS Graviton Neoverse-V2 processor running at 2.8 GHz. Operating on the Nitro hypervisor, it includes 64.0 GB of RAM and delivers a baseline network bandwidth of 67 Gbps, though it lacks local storage and GPU accelerators. Benchmarks highlight top-tier memory bandwidth and multi-core performance, alongside strong database operations and static web serving throughput. Conversely, single-core execution and LLM inference tasks show average to weak performance. Qualitatively, its ARM64 architecture offers high resource density and memory efficiency for multi-threaded tasks. This server is highly suited for high-throughput web serving, database operations, software compilation, and multi-threaded data processing.

      Workload Profiles

      2.6Score
      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.
