      Server Description

      A balanced general-purpose virtual machine featuring high-frequency Intel Xeon processors, DDR5 memory, and advanced matrix acceleration for diverse enterprise workloads.

      General Purpose

      Amazon Web Services m8i-flex.8xlarge is a general-purpose instance featuring 32 vCPUs and 16 physical cores powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is configured with 128.0 GB of DDR5 memory at 7 GHz, but lacks local storage and dedicated GPUs. Operating on the Nitro hypervisor, the instance supports advanced instruction sets including AVX-512 and Intel AMX. In benchmark testing, the server exhibits strong performance in text processing, single-threaded compression, and small-model LLM text generation, though it shows limitations in large-model LLM text generation. With a baseline network bandwidth of 8 Gbps, this instance is qualitatively cost-efficient for balanced workloads. It is well-suited for applications such as static web serving, database operations, and medium-scale enterprise applications.

      Workload Profiles

      2.7Score
      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.
