Server Description
An arm64 memory-optimized instance delivering high memory bandwidth and dedicated physical cores for intensive database and caching workloads.
Amazon Web Services x8g.16xlarge is an arm64 memory-optimized instance featuring 64 dedicated physical cores powered by AWS Graviton Neoverse-V2 processors running at 2.8 GHz. It is equipped with 1024.0 GB of RAM, providing a high memory-to-core ratio of 16.0 GB per core, alongside a 30 Gbps baseline network bandwidth. The instance does not include local storage or GPUs. Benchmark results indicate top-tier memory bandwidth, with uncached read speeds of 456.97 GB/sec, and strong multi-core performance, highlighted by a Geekbench multi-core score of 25533.0. Database and caching performance are also top-tier, with Redis SET operations reaching 132.1 million operations per second. This profile makes the instance highly efficient for memory-intensive workloads such as in-memory databases, Redis caching, software compilation, and high-throughput web serving, offering a strong balance of memory density and multi-core processing without the overhead of simultaneous multithreading.
