      Server Description

      A compute-optimized, network-enhanced virtual server featuring dedicated Intel Xeon processors and high-speed network bandwidth for demanding workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6in.4xlarge is a compute-optimized instance utilizing the AWS Nitro hypervisor and an x86_64 Intel Xeon 8375C processor. Operating at 3.5 GHz, it delivers 16 dedicated vCPUs, 32.0 GB of DDR4 memory, and a baseline network bandwidth of 25 Gbps. The instance lacks local storage and GPU accelerators, relying entirely on network-attached storage. Benchmark data shows solid mid-range performance, with a PassMark CPU score of 21375.14 and a Redis SET throughput of 15.84 million operations per second. While highly capable for network-bound and compute-heavy tasks, its memory-to-vCPU ratio of 2.0 GB per core and lack of local NVMe storage represent key tradeoffs. It is best suited for static web serving, software compilation, network-optimized applications, and moderate database workloads.

      Workload Profiles

      1.03Score
      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.
