      Server Description

      An ARM64 memory-optimized instance featuring sixty-four dedicated cores and top-tier memory bandwidth for database and caching workloads.

      Memory Optimized

      Amazon Web Services r8g.16xlarge is an ARM64 memory-optimized server instance featuring 64 dedicated physical cores powered by the AWS Neoverse-V2 processor at 2.8 GHz. Running on the Nitro hypervisor, it delivers 512.0 GB of RAM, equivalent to 8.0 GB per core, with a baseline network bandwidth of 30 Gbps and no local storage or GPU. Benchmark data shows top-tier memory bandwidth and database performance, with Redis SET operations achieving 132.23 million operations per second. While single-core performance and small-model LLM text generation are average to weak, multi-core execution, software compilation, and larger LLM text generation are strong to top-tier. This profile makes the instance highly efficient for memory-intensive workloads, database management, and caching, though users must plan for network-attached storage.

      Workload Profiles

      5.06Score
      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.
