      Server Description

      An ARM64 memory-optimized server featuring ninety-six dedicated cores and high-bandwidth memory for demanding database and caching workloads.

      Memory OptimizedCompute OptimizedStorage & Database

      Amazon Web Services r8gb.24xlarge is an ARM64 memory-optimized server featuring 96 dedicated physical cores on the AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It is equipped with 768.0 GB of RAM, yielding an 8.0 GB per core ratio, and delivers a baseline network bandwidth of 200 Gbps without local storage or GPU accelerators. Benchmarks indicate top-tier multi-core and memory subsystem performance, with Redis SET operations reaching 198.49 million operations per second and uncached memory read bandwidth at 481.61 GB/sec. However, single-core metrics and small-model LLM text generation show average to weak performance. This profile makes the instance highly efficient for memory-intensive, network-bound workloads such as in-memory databases, distributed caching, and high-throughput web serving, offering strong resource density for enterprise-scale memory requirements.

      Workload Profiles

      5.8Score
      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.
