      Server Description

      A dedicated 32-vCPU compute-optimized instance featuring Intel Xeon processors and DDR4 memory for high-density CPU workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6i.8xlarge is a compute-optimized instance featuring 32 vCPUs and 16 physical cores powered by a dedicated 3.5 GHz Intel Xeon 8375C processor. Built on the x86_64 architecture and managed by the Nitro hypervisor, it includes 64.0 GB of DDR4 memory, providing 2.0 GB per core. The instance lacks local storage and dedicated GPUs, relying on a 12 Gbps baseline network bandwidth. Benchmark data shows average tier performance across standard compute metrics, with a Passmark CPU score of 36326.98 and a Geekbench multi-core score of 13945.0. It exhibits strong performance in text generation for small 135M LLM models at 303.91 tokens/sec, but drops to a weak 6.2 tokens/sec for large 70B models. This hardware profile is suited for CPU-bound tasks like software compilation, web serving, and moderate database operations.

      Workload Profiles

      1.77Score
      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.
