      Server Description

      A high-density, compute-optimized platform featuring 128 dedicated vCPUs and DDR5 memory for intensive parallel processing and database workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8i.32xlarge is an x86_64 compute-optimized instance featuring 128 dedicated vCPUs powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is equipped with 256.0 GB of DDR5 memory at 7 GHz, providing a 2.0 GB memory-to-core ratio, and delivers a baseline network bandwidth of 50 Gbps. The instance lacks local storage and GPUs. Benchmark results show top-tier multi-core CPU performance, high memory bandwidth, and strong capabilities in software compilation, database operations, and CPU-based LLM inference. It is highly suited for compute-intensive workloads, including high-throughput web serving, large-scale compilation, and mathematical simulations, offering high resource density for parallel processing tasks.

      Workload Profiles

      7.81Score
      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.
