      Server Description

      A high-density memory-optimized platform featuring three terabytes of DDR5 RAM and advanced matrix extensions for massive enterprise database workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8i.96xlarge is a memory-optimized server instance powered by the Nitro hypervisor and an Intel Xeon 6975P-C processor. It delivers 384 vCPUs, 192 physical cores, and 3072.0 GB of DDR5 memory running at 7 GHz. Designed for memory-intensive applications, the instance achieves top-tier multi-core CPU performance and exceptional memory bandwidth, as demonstrated by its high throughput in database operations and Redis SET benchmarks. However, it lacks local storage and exhibits average single-core performance. It supports advanced vector and matrix extensions for accelerated mathematical computations. This instance is highly suited for large-scale in-memory databases, enterprise database operations, and heavy multi-threaded data processing workloads.

      Workload Profiles

      14.2Score
      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.
