      Server Description

      A dedicated 32-core ARM64 compute-optimized platform delivering top-tier memory bandwidth and high-throughput network performance for parallel workloads.

      Compute Optimized

      Amazon Web Services c8gb.8xlarge is a compute-optimized instance featuring 32 dedicated ARM64 physical cores powered by AWS Graviton Neoverse-V2 processors running at 2.8 GHz. It is equipped with 64.0 GB of RAM, providing a 2.0 GB per core ratio, and operates on the Nitro hypervisor with a 67 Gbps baseline network bandwidth. This instance does not include local storage or GPU accelerators. In benchmark testing, the c8gb.8xlarge demonstrates top-tier memory bandwidth and multi-core Geekbench performance, alongside strong database and static web serving capabilities. However, it exhibits weaker performance in LLM text generation and prompt processing. This profile makes the instance highly efficient for parallelized workloads, software compilation, and high-throughput database operations, while presenting a tradeoff for large language model inference.

      Workload Profiles

      2.61Score
      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.
