      Server Description

      A dedicated 32-core ARM64 compute-optimized instance delivering 100 Gbps network bandwidth and top-tier memory throughput for demanding workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8gn.8xlarge is an ARM64 compute-optimized server powered by a 32-core AWS Graviton Neoverse-V2 processor running at 2.8 GHz. Operating on the Nitro hypervisor, it features 32 dedicated physical cores, 64.0 GB of system memory, and a baseline network bandwidth of 100 Gbps, with no local storage or GPU hardware. Benchmark results highlight top-tier memory bandwidth and database operations, alongside strong multi-core performance in Geekbench and software compilation. However, large-model LLM inference presents a performance tradeoff, scoring in the bottom 25% for 70B model prompt processing. This instance provides qualitative cost efficiency for high-throughput, network-bound, and compute-intensive workloads. It is highly suited for database operations, static web serving, software compilation, and multi-threaded decompression tasks.

      Workload Profiles

      3Score
      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.
