      CPU and System Topology

      Server Description

      A memory-optimized x86_64 platform featuring two terabytes of DDR5 RAM and high-core-count Intel Xeon processors for enterprise workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services x8i.32xlarge is a memory-optimized server featuring 128 vCPUs on 64 physical Intel Xeon 6975P-C cores running at 3.9 GHz. It is configured with 2048.0 GB of DDR5 memory operating at 7 GHz, offering a high memory-to-vCPU ratio of 16.0 GB per core. The server lacks local storage and dedicated GPUs but provides a baseline network bandwidth of 50 Gbps. Powered by the Nitro hypervisor, it delivers top-tier multi-core CPU performance, high cached memory bandwidth, and strong multi-threaded decompression capabilities. Advanced instruction support, including AVX-512 and Intel AMX, enables top-tier performance in LLM inference prompt processing. This instance is optimized for memory-intensive applications, large database operations, Redis caching, and multi-threaded enterprise workloads.

      Workload Profiles

      7.56Score
      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.
