      Server Description

      A high-capacity memory-optimized instance featuring ninety-six vCPUs and DDR5 memory for demanding database and data processing workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8i.24xlarge is a memory-optimized server instance featuring 96 dedicated vCPUs and 768.0 GB of DDR5 RAM. Powered by Intel Xeon 6975P-C processors running at 3.9 GHz, this x86_64 instance utilizes the Nitro hypervisor and delivers 40 Gbps of baseline network bandwidth. It does not include local storage or GPUs. Benchmarks indicate top-tier memory read bandwidth of up to 7,675.4 GB/sec and strong multi-core performance, with a PassMark CPU score of 106,946.29. The hardware supports advanced instruction sets like AVX-512 and Intel AMX, making it highly effective for memory-intensive database operations, Redis deployments, and CPU-based machine learning inference.

      Workload Profiles

      6.4Score
      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.
