      Server Description

      A high-density, compute-optimized x86 platform featuring 384 vCPUs and advanced matrix extensions for demanding parallel processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8i.96xlarge is a compute-optimized instance featuring 384 vCPUs and 192 physical cores powered by dedicated Intel Xeon 6975P-C processors at 3.9 GHz. It is equipped with 768.0 GB of DDR5 memory running at 7 GHz, delivering 2.0 GB of RAM per vCPU, but lacks local storage and dedicated GPUs. Operating on the AWS Nitro hypervisor, the instance supports advanced instruction sets like AVX-512 and Intel AMX. Benchmarks show top-tier multi-core CPU performance, exceptional memory bandwidth, and strong cryptographic execution, though text generation for small LLMs is a notable tradeoff. With a 100 Gbps baseline network bandwidth, this instance is highly cost-efficient for compute-dense, network-reliant workloads. It is best suited for high-performance computing, software compilation, database operations, and static web serving.

      Workload Profiles

      14.1Score
      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.
