      CPU and System Topology

      Server Description

      A high-density, compute-optimized server with dedicated Intel Xeon processors and DDR5 memory for demanding multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8i.24xlarge is a compute-optimized instance featuring 96 dedicated vCPUs and 48 physical cores powered by an Intel Xeon 6975P-C processor running at 3.9 GHz. Built on the x86_64 architecture and the Nitro hypervisor, it includes 192.0 GB of high-speed 7 GHz DDR5 memory, a 480 MB L3 cache, and advanced instruction sets like AVX-512 and AMX. The instance lacks local storage and GPUs but provides a 40 Gbps baseline network bandwidth. Benchmarks highlight top-tier multi-core performance, with a PassMark CPU score of 106,933.38 and a Redis throughput of 171.2 million SET operations per second. It also delivers strong LLM prompt processing speeds. This server is highly suited for compute-intensive workloads, including software compilation, database operations, static web serving, and CPU-based machine learning inference.

      Workload Profiles

      6.2Score
      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.
