      Server Description

      A compute-optimized virtual server with dedicated Intel Xeon processors, designed for single-threaded tasks and lightweight utility workloads.

      Compute Optimized

      Amazon Web Services c6i.xlarge is a compute-optimized instance featuring 4 dedicated vCPUs across 2 physical Intel Xeon 8375C cores running at 3.5 GHz. It is configured with 8.0 GB of DDR4 memory, providing a 1:2 vCPU-to-RAM ratio, and relies on network-attached storage with a baseline network bandwidth of 2 Gbps. Performance benchmarks indicate average single-core capabilities, though multi-core scaling and memory bandwidth are relatively weak, placing in the bottom quartile. The instance supports advanced instruction sets such as AVX-512 and SHA-NI, making it suitable for compute-bound tasks that do not require high memory density. The c6i.xlarge is best deployed for lightweight web serving, single-threaded batch processing, and basic utility workloads.

      Workload Profiles

      0.329Score
      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.
