      Server Description

      An ARM64 memory-optimized instance featuring high memory density and strong memory bandwidth for caching and in-memory database workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services x8g.2xlarge is a memory-optimized server powered by an 8-core ARM64 AWS Graviton Neoverse-V2 processor running at 2.8 GHz. Operating on the Nitro hypervisor, it features 128.0 GB of RAM, translating to a high density of 16.0 GB per core. The instance lacks local storage and GPU accelerators, but provides a 4 Gbps baseline network bandwidth. Benchmark data highlights top-tier memory performance and strong single-threaded bzip3 decompression, though cryptographic and LLM inference capabilities are weaker. This profile makes the x8g.2xlarge highly cost-efficient for memory-intensive workloads like caching layers and in-memory databases that do not require local NVMe storage.

      Workload Profiles

      1.1Score
      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.
