      Server Description

      A high-density general-purpose platform featuring sixty-four dedicated processor cores and fast DDR5 memory for demanding multi-threaded enterprise workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8i.16xlarge is a general-purpose instance featuring 64 dedicated vCPUs powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. Built on the Nitro hypervisor, it includes 256 GB of DDR5 memory at 7 GHz, providing a balanced 4 GB of RAM per vCPU, but lacks local storage and GPU accelerators. The instance delivers top-tier performance in multi-core benchmarks, software compilation, and static web serving, which reaches 107.39 GB/sec. It also features advanced instruction sets like AVX-512 and Intel AMX, aiding in tasks like prompt processing for large language models. With a baseline network bandwidth of 30 Gbps, this instance is optimized for resource-dense, multi-threaded workloads. It is highly suitable for enterprise web serving, software build pipelines, Redis databases, and CPU-based machine learning inference.

      Workload Profiles

      4.59Score
      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.
