      Server Description

      A high-core-count general-purpose instance featuring DDR5 memory and advanced matrix extensions for accelerated multi-threaded enterprise workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8i.32xlarge is a general-purpose instance featuring 128 vCPUs and 512.0 GB of DDR5 memory. Powered by an Intel Xeon 6975P-C processor running at 3.9 GHz, this instance utilizes the Nitro hypervisor and provides a baseline network bandwidth of 50 Gbps. While it lacks local storage and dedicated GPUs, it delivers top-tier multi-core CPU performance and memory bandwidth, ranking in the top 10% of several benchmarks. The processor includes Advanced Matrix Extensions and Advanced Vector Extensions, which significantly accelerate workloads like LLM inference and database operations. The m8i.32xlarge is qualitatively cost-efficient for high-density, multi-threaded enterprise applications, making it highly suitable for large-scale web serving, database management, and CPU-based machine learning tasks.

      Workload Profiles

      7.42Score
      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.
