      Server Description

      A compute-optimized instance featuring dedicated Intel Xeon processors, DDR5 memory, and advanced matrix extensions for intensive computational workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8i.8xlarge is an x86_64 compute-optimized instance powered by a 3.9 GHz Intel Xeon 6975P-C processor with 32 vCPUs and 16 physical cores. Running on the Nitro hypervisor, it features 64.0 GB of DDR5 memory at 7 GHz, offering a memory-to-core ratio of 2.0 GB. The processor includes a 480 MB L3 cache and supports Intel Advanced Matrix Extensions (AMX) and AVX-512. While it lacks local storage, it provides a baseline network bandwidth of 15 Gbps. Benchmark data shows top-tier performance in image and text processing, alongside strong results in single-threaded compression and small-model LLM inference. Conversely, its multi-core stress-ng and memory bandwidth benchmarks sit in the average tier. This instance is suited for compute-intensive workloads such as software compilation, static web serving, and medium-scale machine learning inference.

      Workload Profiles

      2.8Score
      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.
