      CPU and System Topology

      Server Description

      A compute-optimized x86_64 platform featuring dedicated Intel Xeon processors and DDR5 memory for high-throughput text processing and inference.

      Compute Optimized

      Amazon Web Services c8i.8xlarge is an x86_64 compute-optimized instance featuring 32 dedicated vCPUs from an Intel Xeon 6975P-C processor running at 3.9 GHz, paired with 64.0 GB of DDR5 memory. Operating on the Nitro hypervisor, it lacks local storage and GPUs, relying on a 15 Gbps baseline network bandwidth. Benchmark results show strong performance, with Geekbench single-core and multi-core scores in the top 25%, and text processing in the top 10%. The CPU includes Advanced Matrix Extensions, enabling top-tier text generation speeds of 357.67 tokens/sec for small LLM models. While the 2:1 RAM-to-vCPU ratio and lack of local storage present tradeoffs for memory-intensive or high-I/O databases, the instance offers high compute density. It is suited for CPU-bound workloads, including software compilation, web serving, text processing, and machine learning inference.

      Workload Profiles

      2.77Score
      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.
