      Server Description

      A compute-optimized instance featuring dedicated Intel Xeon processors and DDR5 memory, delivering strong single-core performance for processing-heavy workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i-flex.8xlarge is an x86_64 compute-optimized instance powered by a 3.2 GHz Intel Xeon 8488C processor and the Nitro hypervisor. It features 32 dedicated vCPUs across 16 physical cores, 64.0 GB of DDR5 memory at 5 GHz, and a baseline network bandwidth of 6 Gbps, with no local storage or GPUs. Benchmarks indicate strong single-core and multi-core performance, with Geekbench scores of 2074.0 and 15951.0 respectively, placing it in the top 25% tier. It also demonstrates strong capabilities in static web serving at 51.12 GB/sec and single-threaded compression tasks. The instance supports advanced instruction sets like AVX-512 and Intel AMX, making it a cost-efficient option for compute-heavy workloads, including web serving, batch processing, and moderate machine learning inference.

      Workload Profiles

      2.28Score
      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.
