      Server Description

      An arm64 memory-optimized instance featuring dedicated physical cores and high-bandwidth memory for memory-intensive database and caching workloads.

      Memory Optimized

      Amazon Web Services r8g.2xlarge is a memory-optimized instance featuring 8 dedicated arm64 physical cores powered by the AWS Graviton Neoverse-V2 processor at 2.8 GHz. It provides 64.0 GB of RAM, yielding a high memory-to-core ratio of 8.0 GB per core, alongside a 36 MB L3 cache and a 4 Gbps baseline network bandwidth. The instance does not include local storage or GPU hardware. Benchmark results show top-tier memory performance, with Passmark memory scores in the top 10% and large-block read bandwidth in the top 25%. However, cryptographic and LLM inference benchmarks show weaker performance, with encryption and medium-model prompt processing scoring in the bottom 25% and 10% respectively. This profile makes the r8g.2xlarge highly efficient for memory-intensive workloads like caching and in-memory databases, while being less suited for compute-heavy cryptography or AI inference.

      Workload Profiles

      1.09Score
      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.
