      CPU and System Topology

      Server Description

      A balanced general-purpose server featuring 64 vCPUs, AVX-512 support, and 256 GB RAM for multi-threaded enterprise workloads.

      General Purpose

      Amazon Web Services m6i.16xlarge is a general-purpose instance featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the x86_64 architecture and managed by the Nitro hypervisor, it includes 256.0 GB of DDR4 memory, providing a balanced 4.0 GB of RAM per vCPU. The server lacks local storage and dedicated GPUs but delivers a baseline network bandwidth of 25 Gbps. Benchmark data highlights strong multi-core CPU performance, particularly in software compilation, database operations, and static web serving, alongside strong cryptographic execution via AVX-512 and AES extensions. Single-core performance and memory bandwidth remain in the average tier. This configuration is optimized for multi-threaded enterprise workloads, web serving, and database applications requiring balanced compute and memory resources.

      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.
