      Server Description

      A dedicated dual-vCPU compute instance featuring Intel Xeon architecture and AVX-512 support for lightweight, single-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6i.large is an x86_64 compute-optimized instance powered by a dedicated 3.5 GHz Intel Xeon 8375C processor. It features 2 vCPUs (1 physical core with hyper-threading), 4.0 GB of DDR4 memory, and a baseline network bandwidth of 1 Gbps, with no local storage or GPU. Running on the Nitro hypervisor, the instance supports advanced instruction sets such as AVX-512 and AES. Benchmark results indicate average single-core CPU performance and single-threaded compression speeds, but poor multi-core scaling and memory bandwidth. Consequently, the instance presents a tradeoff between dedicated single-core compute capability and limited multi-threaded capacity. It is qualitatively cost-efficient for lightweight, compute-bound tasks but struggles with memory-intensive operations. The c6i.large is best suited for basic web serving, single-threaded processing, and small-scale computational workloads.

      Workload Profiles

      0.193Score
      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.
