      Server Description

      A high-density, multi-core compute instance featuring dedicated Intel Xeon processors and 50 Gbps network bandwidth for parallelized workloads.

      Compute Optimized

      Amazon Web Services c6i.32xlarge is an x86_64 compute-optimized server instance utilizing the Nitro hypervisor. It features 128 dedicated vCPUs (64 physical cores) powered by Intel Xeon 8375C processors running at 3.5 GHz, paired with 256.0 GB of DDR4 memory. The instance does not include local storage or GPUs, but provides a 50 Gbps baseline network bandwidth. Benchmark data indicates average single-core performance but strong multi-core execution, with top-tier results in Passmark CPU and encryption tests. The 2.0 GB of memory per core represents a tradeoff for memory-intensive applications, making the instance highly efficient for parallel, compute-bound workloads. It is suited for software compilation, multi-threaded decompression, database operations, and static web serving.

      Workload Profiles

      4.68Score
      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.
