      Server Description

      A compute-optimized, network-enhanced instance featuring sixty-four virtual CPUs and high-speed network bandwidth for demanding parallel processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6in.16xlarge is a compute-optimized instance featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the Nitro hypervisor, it provides 128.0 GB of DDR4 memory, yielding a 2.0 GB per core ratio, with no local storage or GPU hardware. The instance delivers strong multi-core CPU performance, particularly in software compilation, ray tracing, and cryptographic operations, though single-core metrics and memory bandwidth remain in the average tier. With a baseline network bandwidth of 100 Gbps, it achieves strong static web serving throughput. This hardware profile is qualitatively cost-efficient for compute-heavy, network-intensive tasks, making it suitable for workloads such as multi-threaded compilation, image processing, and web serving.

      Workload Profiles

      2.78Score
      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.
