      Server Description

      An ARM64 compute-optimized instance delivering high-bandwidth networking, top-tier memory throughput, and 48 dedicated physical cores for multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      The Amazon Web Services c8gn.12xlarge is an ARM64 compute-optimized server powered by 48 dedicated physical cores of the AWS Graviton ARMv9 Neoverse-V2 processor. Operating at 2.8 GHz on the Nitro hypervisor, it features 96.0 GB of memory and a 150 Gbps baseline network bandwidth, with no local storage or GPUs. Benchmarks show top-tier performance in large-block memory bandwidth, software compilation, and static web serving throughput, alongside strong multi-core processing. However, single-core performance and small-model text generation remain average to weak. This resource profile offers high compute density and memory throughput, making it suitable for multi-threaded workloads, software compilation, database operations, and high-bandwidth web serving, while requiring network-attached storage for disk-heavy tasks.

      Workload Profiles

      3.7Score
      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.
