      Server Description

      An arm64 memory-optimized instance featuring one terabyte of RAM and dedicated physical cores for high-throughput database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services x8g.16xlarge is an arm64 memory-optimized server instance powered by 64 dedicated AWS Neoverse-V2 physical cores running at 2.8 GHz. It features 1024.0 GB of RAM, yielding a high resource density of 16.0 GB per core, and operates on the Nitro hypervisor with 30 Gbps baseline network bandwidth and no local storage. Benchmark results show top-tier memory bandwidth, database operations, and Redis SET performance, alongside strong multi-core CPU capabilities. Conversely, single-core processing speeds remain in the average tier. Qualitatively, the Arm-based architecture provides high resource density and cost-efficient memory scaling, though the lack of local storage and GPU acceleration represents a clear hardware tradeoff. This instance is suited for in-memory databases, caching layers, software compilation, and high-throughput web serving.

      Workload Profiles

      4.84Score
      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.
