      Server Description

      A compute-optimized x86 server featuring dedicated Intel Xeon processors and balanced memory bandwidth for web serving and batch processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6i.4xlarge is a compute-optimized instance featuring 16 dedicated vCPUs and 8 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is equipped with 32.0 GB of DDR4 memory, providing a 2.0 GB per vCPU ratio, and operates on the AWS Nitro hypervisor. The instance lacks local storage and GPU hardware, relying on a 6 Gbps baseline network bandwidth. Benchmark data indicates average performance, with a Geekbench multi-core score of 9680.0, a static web serving throughput of 22.41 GB/sec, and 15.63 million Redis SET operations per second. While it exhibits weak performance on larger LLM prompt processing, it remains efficient for compute-bound tasks. The c6i.4xlarge is suited for workloads such as web serving, batch processing, and moderate CPU-based inference.

      Workload Profiles

      1.04Score
      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.
