      CPU and System Topology

      Server Description

      A high-density, compute-optimized platform featuring 192 vCPUs and advanced matrix extensions for demanding parallel processing and database workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8i.48xlarge is a compute-optimized instance featuring 192 vCPUs and 96 physical Intel Xeon 6975P-C cores running at 3.9 GHz on the x86_64 architecture. Built on the AWS Nitro hypervisor, it includes 384.0 GB of DDR5 memory at 7 GHz but lacks local storage and GPUs. The instance delivers top-tier multi-core CPU performance, memory bandwidth, and database operations, supported by advanced instruction sets like AVX-512 and Intel AMX. While single-core performance is moderate, its massive parallel processing capabilities and 75 Gbps baseline network bandwidth make it highly efficient for multi-threaded workloads. It is best suited for high-performance computing, software compilation, large-scale database operations, and LLM inference.

      Workload Profiles

      9.03Score
      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.
