      CPU and System Topology

      Server Description

      An x86_64 compute-optimized instance featuring dedicated Intel Xeon processors and DDR5 memory for single-threaded and text processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8i.2xlarge is an x86_64 compute-optimized server instance featuring 8 dedicated vCPUs powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. It is equipped with 16.0 GB of DDR5 memory at 7 GHz, a 480 MB L3 cache, and a baseline network bandwidth of 4 Gbps, with no local storage or GPU hardware. Benchmarks indicate strong single-threaded capabilities, with top-tier text processing performance and strong single-threaded gzip compression. Multi-core performance, memory bandwidth, and database operations align with average tiers. The instance supports advanced instruction sets like AVX-512 and AMX, making it qualitatively cost-effective for compute-heavy tasks. However, the 2.0 GB of RAM per core ratio presents a tradeoff for memory-intensive applications. It is best suited for software compilation, text processing, lightweight model inference, and general compute-bound workloads.

      Workload Profiles

      0.936Score
      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.
