      CPU and System Topology

      Server Description

      A high-density ARM64 server featuring 1.5 TB of memory and 192 dedicated cores for memory-intensive parallel workloads.

      Amazon Web Services r8g.48xlarge is a memory-optimized server instance powered by the AWS Nitro hypervisor and 192 dedicated ARM64 physical cores on AWS Neoverse-V2 processors running at 2.7 GHz. It features 1536.0 GB of system memory, providing 8.0 GB of RAM per core, alongside a baseline network bandwidth of 50 Gbps. The instance does not include local storage or GPU accelerators. Benchmark results indicate top-tier multi-core CPU performance, memory bandwidth, and database operations, though single-core performance and small-model LLM prompt processing are relatively weaker. This hardware profile is suited for memory-intensive, highly parallel workloads such as in-memory databases, caching layers, and large-scale software compilation.

      Workload Profiles

      11Score
      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.
