      Server Description

      A high-capacity bare-metal server featuring 1.5 TB of DDR5 memory and 192 vCPUs for demanding in-memory database workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8i.metal-48xl is a bare-metal, memory-optimized server designed for resource-intensive enterprise workloads. It features 192 vCPUs across 96 physical Intel Xeon 6975P-C cores running at 3.9 GHz, paired with 1536.0 GB of DDR5 memory. The architecture supports advanced vector and matrix extensions (AVX-512 and AMX), driving top-tier multi-core and memory bandwidth performance. Benchmarks show exceptional capabilities in database operations, with Redis SET performance reaching 296.12 million operations per second, and strong LLM prompt processing speeds. While the server lacks local storage, its 75 Gbps baseline network bandwidth ensures efficient connectivity to network storage. This instance is highly suited for in-memory databases, large-scale data processing, and complex multi-threaded enterprise applications.

      Workload Profiles

      9.2Score
      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.
