      Server Description

      A compute-optimized instance featuring high-speed DDR5 memory and advanced Intel matrix extensions for intensive CPU-bound workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i.8xlarge is a compute-optimized instance featuring 32 vCPUs and 16 physical cores powered by an Intel Xeon 8488C processor at 3.2 GHz. Built on the x86_64 architecture and the Nitro hypervisor, it includes 64.0 GB of DDR5 memory running at 5 GHz, yielding a 1:2 vCPU-to-RAM ratio. The processor supports advanced instruction sets like AVX-512 and Intel AMX. While it lacks local storage and GPUs, it delivers a baseline network bandwidth of 12 Gbps. Benchmarks highlight strong performance in static web serving (48.15 GB/sec), single-threaded gzip compression (32.2 GB/sec), and small-model LLM text generation (380.26 tokens/sec). This profile makes it highly suitable for compute-intensive workloads such as web serving, software compilation, and CPU-based machine learning inference.

      Workload Profiles

      2.1Score
      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.
