      Server Description

      A cost-efficient compute-optimized instance featuring dedicated Intel Xeon processors and DDR5 memory for moderate single-threaded workloads.

      Compute Optimized

      Amazon Web Services c7i-flex.xlarge is a compute-optimized instance featuring 4 dedicated vCPUs and 8.0 GB of DDR5 memory. Powered by an Intel Xeon 8488C processor at 3.2 GHz under the Nitro hypervisor, it delivers solid single-core performance, as evidenced by a Geekbench single-core score of 1912.0. However, multi-core and memory bandwidth benchmarks are relatively weak, with a Passmark memory score in the bottom 10%. The instance lacks local storage and GPUs, and provides a baseline network speed of 1 Gbps. It supports advanced instruction sets like AVX-512 and AMX. This server is a cost-effective choice for workloads requiring moderate compute power with low memory demands, such as static web serving, basic text processing, and light single-threaded batch jobs.

      Workload Profiles

      0.46Score
      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.
