      Server Description

      An ARM64 compute-optimized server featuring dedicated physical cores, high-speed memory bandwidth, and 150 Gbps baseline network performance.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7gn.12xlarge is an ARM64 compute-optimized server featuring 48 dedicated physical cores of the AWS Graviton Neoverse-V1 processor running at 2.6 GHz. It is configured with 96.0 GB of system memory, providing a 2.0 GB per core ratio, and includes no local storage or GPU accelerators. Built on the Nitro hypervisor, the instance delivers a baseline network bandwidth of 150 Gbps. Benchmark results show strong multi-core CPU capabilities and top-tier memory bandwidth, with Passmark memory scores in the top 10% and stress-ng multi-core performance in the top 25%. Conversely, single-core metrics and LLM inference speeds remain in the average middle 50% tier. This profile makes the c7gn.12xlarge highly effective for network-intensive applications, software compilation, and database operations, though the absence of local NVMe storage and x86 vector instructions are notable tradeoffs.

      Workload Profiles

      2.82Score
      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.
