      Server Description

      A cost-efficient, compute-optimized virtual instance featuring DDR5 memory and advanced matrix extensions for accelerated processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i-flex.4xlarge is an x86_64 compute-optimized instance powered by an Intel Xeon 8488C processor running at 3.2 GHz. It features 16 dedicated vCPUs (8 physical cores), 32.0 GB of DDR5 memory at 5 GHz, and a baseline network bandwidth of 3 Gbps, with no local storage or GPUs. The instance delivers strong single-core performance, highlighted by a Geekbench single-core score of 2045.0 and a single-threaded gzip compression rate of 33.24 GB/sec. Its processor supports advanced vector and matrix extensions (AVX-512 and AMX), enabling efficient execution of mathematical and cryptographic operations. Positioned as a resource-dense and cost-efficient option within the compute-optimized class, the c7i-flex.4xlarge is designed for workloads such as web serving, batch processing, software compilation, and small-to-medium scale machine learning inference.

      Workload Profiles

      1.3Score
      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.
