      Server Description

      A high-frequency, memory-optimized server featuring one terabyte of DDR5 RAM and top-tier multi-core processing capabilities for demanding enterprise workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7iz.32xlarge is a memory-optimized server powered by the Nitro hypervisor and an Intel Xeon 6455B processor. It features 128 vCPUs, 64 physical cores running at 3.9 GHz, and 1024.0 GB of DDR5 memory operating at 5 GHz. The instance does not include local storage or GPUs, but provides a baseline network bandwidth of 50 Gbps. Benchmark results place this server in the top tier for multi-core CPU performance, memory bandwidth, and database operations, with Redis SET performance reaching 149.32 million operations per second. It also delivers top-tier performance in LLM inference for medium-sized models. The r7iz.32xlarge is designed for memory-intensive and high-compute workloads, making it highly suitable for in-memory databases, large-scale caching layers, and enterprise software compilation.

      Workload Profiles

      6.32Score
      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.
