      Server Description

      An arm64 memory-optimized instance featuring high memory bandwidth, dedicated Graviton cores, and optimized network performance for database workloads.

      Memory Optimized

      Amazon Web Services r8gn.2xlarge is an arm64 memory-optimized instance powered by an 8-core AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It features 64.0 GB of RAM, providing a high 8.0 GB per core ratio, and operates on the Nitro hypervisor with a 25 Gbps baseline network bandwidth and no local storage. Benchmark results highlight top-tier memory performance, with a PassMark memory score in the top 10% and memory bandwidth reaching up to 925.05 GB/sec for cached reads. While single-threaded bzip3 decompression is strong, CPU encryption and LLM inference speeds are weak. This profile makes the instance highly efficient for memory-intensive applications, database operations, and Redis caching, while presenting tradeoffs for cryptographic and machine learning workloads.

      Workload Profiles

      0.91Score
      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.
