      CPU and System Topology

      Server Description

      A high-density memory-optimized server featuring 128 vCPUs and 2 TB of DDR5 RAM for memory-intensive enterprise workloads.

      Memory OptimizedCompute OptimizedGeneral Purpose

      Amazon Web Services x8i.32xlarge is a memory-optimized server powered by the Nitro hypervisor and an Intel Xeon 6975P-C processor. Operating on the x86_64 architecture, it provides 128 vCPUs across 64 physical cores at 3.9 GHz, paired with 2048.0 GB of DDR5 memory running at 7 GHz. The instance lacks local storage and GPUs but delivers a baseline network bandwidth of 50 Gbps. Benchmark data highlights top-tier multi-core CPU performance, exceptional memory bandwidth, and top-tier results in Redis SET operations and static web serving. The processor includes AVX-512 and AMX extensions, facilitating top-tier performance in extended instructions and prompt processing for large language models. This instance is optimized for memory-intensive workloads, including in-memory databases, software compilation, and CPU-based LLM inference.

      Workload Profiles

      7.3Score
      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.
