      Server Description

      A high-density, memory-optimized server featuring 128 vCPUs and 1 TB of DDR5 RAM for demanding enterprise database workloads.

      Memory OptimizedCompute OptimizedGeneral Purpose

      Amazon Web Services r8i.32xlarge is a memory-optimized server featuring 128 dedicated vCPUs from 64 physical Intel Xeon 6975P-C cores running at 3.9 GHz, paired with 1024.0 GB of high-speed 7 GHz DDR5 memory. Operating on the Nitro hypervisor, this instance lacks local storage and GPUs but provides a baseline network bandwidth of 50 Gbps. It delivers top-tier multi-core CPU and memory bandwidth performance, supported by Intel Advanced Matrix Extensions (AMX) and AVX-512 instructions. Benchmark data highlights exceptional throughput in multi-threaded tasks, Redis operations, and CPU-based LLM prompt processing. This configuration is highly efficient for memory-intensive enterprise workloads, including large-scale databases, in-memory caches, and complex data processing pipelines.

      Workload Profiles

      7.4Score
      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.
