      Server Description

      A compute-optimized virtual server featuring high-speed DDR5 memory and advanced Intel Xeon processing for demanding multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i-flex.8xlarge is a compute-optimized virtual server running on the Nitro hypervisor. It is equipped with an x86_64 Intel Xeon 8488C processor operating at 3.2 GHz, delivering 32 vCPUs across 16 physical cores. The instance features 64.0 GB of high-speed DDR5 memory at 5 GHz, providing 2.0 GB of RAM per core, but does not include local storage or GPU accelerators. Baseline network bandwidth is rated at 6 Gbps. Benchmark results show strong performance in single-core and multi-core operations, with a Geekbench single-core score of 2074.0 and a multi-core score of 15951.0. It also excels in cryptographic tasks and static web serving, reaching a throughput of 51.12 GB/sec. This resource profile makes the c7i-flex.8xlarge highly suitable for compute-heavy workloads such as software compilation, data compression, static web serving, and small-to-medium scale machine learning inference.

      Workload Profiles

      2.3Score
      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.
