      Server Description

      A balanced general-purpose instance featuring high-speed DDR5 memory, strong single-core performance, and advanced Intel matrix math acceleration.

      General Purpose

      The Amazon Web Services m8i-flex.4xlarge is an x86_64 general-purpose instance featuring an Intel Xeon 6975P-C processor with 16 vCPUs, 8 physical cores, and a 3.9 GHz clock speed. Equipped with 64.0 GB of DDR5 memory at 7 GHz, it provides a balanced 4.0 GB of RAM per core but lacks local storage and dedicated GPUs. It operates on the Nitro hypervisor with a baseline network bandwidth of 4 Gbps. Performance benchmarks highlight top-tier single-core and text processing capabilities, alongside strong single-threaded compression speeds. The processor's support for Intel Advanced Matrix Extensions (AMX) and Advanced Vector Extensions (AVX-512) enables efficient execution of vector and matrix operations. This instance is well-suited for general-purpose applications, web serving, text processing, and small-scale language model inference.

      Workload Profiles

      1.64Score
      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.
