      Server Description

      A bare-metal platform featuring 1.5 TB of DDR5 memory and advanced matrix extensions for memory-intensive enterprise workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services r8i.metal-48xl is a memory-optimized bare-metal server featuring 192 vCPUs across 96 physical Intel Xeon 6975P-C cores running at 3.9 GHz. It is equipped with 1536.0 GB of high-speed 7 GHz DDR5 memory, providing 8.0 GB of RAM per core, and offers a baseline network bandwidth of 75 Gbps. The server lacks local storage and dedicated GPUs. Performance benchmarks show top-tier capabilities in multi-core processing, memory bandwidth, and database operations, though single-core performance is more moderate. Advanced instruction support includes AVX-512 and Intel AMX, which drive top-tier prompt processing speeds for LLM inference. This instance is suited for memory-intensive enterprise applications, large-scale in-memory databases, and CPU-based machine learning workloads.

      Workload Profiles

      9.48Score
      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.
