      Server Description

      A high-density, compute-optimized virtual server featuring 128 vCPUs, 200 Gbps network bandwidth, and advanced cryptographic instruction support.

      Compute Optimized

      Amazon Web Services c6in.32xlarge is an x86_64 compute-optimized instance featuring 128 vCPUs and 64 physical cores powered by Intel Xeon 8375C processors running at 3.5 GHz. Built on the AWS Nitro hypervisor, it includes 256.0 GB of DDR4 memory at 3 GHz, yielding a 2.0 GB per core ratio. The instance lacks local storage and GPUs but offers a high baseline network bandwidth of 200 Gbps. Benchmark data indicates top-tier performance in Passmark CPU and encryption tests, alongside strong multi-core processing and memory bandwidth. It is highly efficient for network-bound and compute-intensive workloads, such as high-throughput web serving, database operations, software compilation, and moderate LLM inference.

      Workload Profiles

      4.5Score
      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.
