      Server Description

      An ARM64 memory-optimized platform featuring ninety-six dedicated cores and high-bandwidth networking for demanding database and multi-threaded workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r8gn.24xlarge is an ARM64 memory-optimized instance featuring 96 dedicated physical cores on the AWS Graviton Neoverse-V2 architecture. Operating at 2.8 GHz, it delivers 768.0 GB of system memory (8.0 GB per core) and a baseline network bandwidth of 300 Gbps, without local storage or GPUs. Benchmarks indicate top-tier multi-core CPU performance, memory bandwidth, and database operations, alongside 198.12 million Redis SET operations per second. While single-core metrics and small-model LLM text generation are moderate to weak, the instance excels in multi-threaded tasks, large-model LLM text generation, and memory-intensive workloads. This hardware profile provides high resource density and qualitative cost efficiency for memory-bound applications, making it suitable for in-memory databases, high-throughput web serving, and large-scale data compilation.

      Workload Profiles

      5.85Score
      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.
