      Server Description

      A memory-optimized platform featuring high-speed DDR5 RAM and advanced matrix extensions for demanding database and memory-intensive workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8i.24xlarge is a memory-optimized instance featuring 96 vCPUs and 48 physical cores powered by Intel Xeon 6975P-C processors at 3.9 GHz. It is equipped with 768.0 GB of DDR5 memory running at 7 GHz, delivering 8.0 GB of RAM per core. The instance operates on the AWS Nitro hypervisor and provides a 40 Gbps baseline network bandwidth, though it lacks local storage and GPU accelerators. Benchmark data shows top-tier performance in memory bandwidth, database operations, and Redis SET operations, alongside strong multi-core CPU capabilities. The processor supports advanced vector and matrix extensions for accelerated mathematical computations. This configuration is designed for memory-intensive workloads, including large database deployments, in-memory data stores, and enterprise-scale data processing.

      Workload Profiles

      6.36Score
      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.
