      Server Description

      A high-capacity memory-optimized instance featuring 128 vCPUs and 1 TB of DDR5 RAM for demanding database and analytical workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8i.32xlarge is a memory-optimized server instance powered by an Intel Xeon 6975P-C processor with 128 vCPUs and 64 physical cores running at 3.9 GHz. It features 1024.0 GB of high-speed 7 GHz DDR5 memory, delivering a balanced 8.0 GB of RAM per core. The instance utilizes the AWS Nitro hypervisor and provides a baseline network bandwidth of 50 Gbps, though it lacks local storage and dedicated GPUs. In benchmark testing, the r8i.32xlarge achieves top-tier multi-core CPU and memory bandwidth performance, ranking in the top 10% for database operations, Redis SET transactions, and multi-threaded decompression. Equipped with Intel Advanced Matrix Extensions (AMX), it also delivers top-tier prompt processing speeds for large language model inference. This instance is designed for memory-intensive enterprise workloads, large relational databases, in-memory caching, and high-throughput data processing.

      Workload Profiles

      7.6Score
      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.
