      Server Description

      A high-density memory-optimized platform featuring three terabytes of DDR5 RAM and three hundred eighty-four virtual cores for massive parallel workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8i.96xlarge is a memory-optimized server designed for high-throughput, memory-intensive workloads. Powered by Intel Xeon 6975P-C processors on the x86_64 architecture, it delivers 384 vCPUs, 192 physical cores, and 3072.0 GB of high-speed DDR5 memory. Running on the Nitro hypervisor, the instance features a 100 Gbps baseline network bandwidth but lacks local storage and GPU accelerators. Benchmark data highlights top-tier multi-core CPU performance, exceptional memory bandwidth, and outstanding database operations, including over 508 million Redis SET operations per second. The integration of Intel Advanced Matrix Extensions accelerates matrix operations, though LLM text generation remains limited by the lack of a GPU. This server is highly efficient for large in-memory databases, intensive data processing, and enterprise applications requiring massive memory capacity and parallel computing power.

      Workload Profiles

      14.3Score
      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.
