      Server Description

      An ARM64-based virtual server featuring sixteen dedicated cores for cost-effective scale-out workloads and multi-threaded application environments.

      Compute OptimizedGeneral Purpose

      Amazon Web Services a1.4xlarge is an ARM64-based instance powered by the first-generation AWS Graviton processor with 16 dedicated physical cores and 16 vCPUs running at 2.3 GHz. It features 32.0 GB of system memory, a 5 Gbps baseline network bandwidth, and runs on the Nitro hypervisor without local storage or GPU accelerators. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 23,858.27 and solid multi-threaded decompression, though single-core performance and uncached memory write bandwidth are weak. This instance is qualitatively cost-effective for scale-out ARM applications, software compilation, and containerized microservices, but is less suitable for memory-intensive or single-threaded workloads.

      Workload Profiles

      0.303Score
      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.
