      Server Description

      A high-frequency bare-metal server combining one terabyte of DDR5 memory with dedicated Intel Xeon processors for demanding database workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7iz.metal-32xl is a memory-optimized bare-metal server powered by a 128-vCPU Intel Xeon 6455B processor running at 3.9 GHz. Built on the x86_64 architecture, it features 1024.0 GB of 5 GHz DDR5 memory, providing 8.0 GB of RAM per core, alongside a 50 Gbps baseline network speed. The server lacks local storage and dedicated GPUs, but delivers top-tier performance across multi-core CPU benchmarks, memory bandwidth, and database operations. It achieves 155.31 million operations per second in Redis SET benchmarks and ranks in the top 10% for Passmark database operations. This hardware profile is highly efficient for memory-intensive enterprise applications, large-scale in-memory databases, and high-performance computing workloads that require dedicated physical resources without virtualization overhead.

      Workload Profiles

      6.4Score
      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.
