      Server Description

      A memory-optimized x86 platform featuring 1.5 TB of DDR5 RAM and 192 vCPUs for demanding database and multi-core workloads.

      Memory OptimizedStorage & DatabaseCompute Optimized

      Amazon Web Services r8i.48xlarge is a memory-optimized server featuring 192 vCPUs and 1536.0 GB of DDR5 memory operating at 7 GHz. Powered by an Intel Xeon 6975P-C processor on the Nitro hypervisor, it delivers top-tier multi-core CPU performance, database operations, and memory bandwidth. The instance lacks local storage and GPUs, relying on a 75 Gbps baseline network bandwidth. While single-core stress tests and text generation speeds represent relative performance tradeoffs in the average to strong tiers, its support for AVX-512 and AMX extensions enables top-tier prompt processing for large language models. This configuration is designed for memory-intensive workloads such as in-memory databases and enterprise data processing.

      Workload Profiles

      9Score
      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.
