      Server Description

      A compute-optimized instance featuring sixty-four virtual cores, high-speed network bandwidth, and dedicated Intel Xeon processing for parallel workloads.

      Compute Optimized

      Amazon Web Services c6in.16xlarge is an x86_64 compute-optimized instance featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is equipped with 128.0 GB of DDR4 RAM, providing 2.0 GB of memory per core, and operates on the Nitro hypervisor. The instance lacks local storage and GPU accelerators but delivers a baseline network bandwidth of 100 Gbps. Benchmark data shows strong multi-core CPU performance, placing in the top 25% for stress-ng multi-core, PassMark CPU, and software compilation tests, while single-core and memory bandwidth metrics remain in the average tier. This hardware profile is configured for network-heavy, compute-intensive workloads such as static web serving, multi-threaded decompression, and database operations, presenting a tradeoff of lower memory density per core.

      Workload Profiles

      2.8Score
      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.
