      CPU and System Topology

      Server Description

      A balanced x86_64 compute platform featuring dedicated Intel Xeon processors and DDR4 memory for standard enterprise workloads.

      General Purpose

      Amazon Web Services m6i.12xlarge is an x86_64 general-purpose instance utilizing the Nitro hypervisor. It is equipped with an Intel Xeon 8375C processor running at 3.5 GHz, delivering 48 vCPUs (24 physical cores) and 192.0 GB of DDR4 memory. The instance has no local storage or GPU accelerators, but provides a baseline network bandwidth of 19 Gbps. Performance benchmarks indicate average capabilities across most compute and memory tasks, with strong results in image processing and CPU encryption. However, a notable tradeoff exists in large-scale machine learning, where text generation for a 70B model drops to a weak 2.75 tokens/second. This instance is configured for balanced workloads such as database operations, software compilation, and static web serving.

      Workload Profiles

      2.3Score
      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.
