Server Description
A dedicated arm64 bare-metal server featuring sixteen physical cores for scale-out workloads and ARM-native application development.
Amazon Web Services a1.metal is a bare-metal server featuring 16 dedicated physical cores on the arm64 architecture, powered by the 2.3 GHz AWS Graviton Cortex-A72 processor. Equipped with 32.0 GB of RAM, 5 Gbps baseline network bandwidth, and no local storage or GPUs, this instance is designed for ARM-native workloads. Benchmarks show average multi-core performance, with a stress-ng multi-core score of 24102.93 and 8.6 million Redis SET operations per second, though single-core and uncached memory write speeds are relatively weak. The lack of hyperthreading provides predictable execution, making it a qualitatively cost-effective option for scale-out applications, software compilation, and lightweight web serving.
