      Server Description

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

      General PurposeCompute Optimized

      The Amazon Web Services m8i.32xlarge is a general-purpose server instance powered by an Intel Xeon 6975P-C processor with 128 vCPUs (64 physical cores) running at 3.9 GHz. It features 512.0 GB of DDR5 memory at 7 GHz, providing a balanced 1:4 vCPU-to-RAM ratio, and offers a baseline network bandwidth of 50 Gbps. The instance lacks local storage and GPU accelerators. In benchmarks, the m8i.32xlarge delivers top-tier multi-core CPU performance, memory bandwidth, and database operations. Its support for Intel Advanced Matrix Extensions (AMX) and AVX-512 enables top-tier performance in cryptography, physics simulations, and CPU-based LLM inference. This instance is highly suited for enterprise databases, static web serving, software compilation, and multi-threaded computational workloads.

      Workload Profiles

      7.46Score
      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.
