Server Description
An ARM64 memory-optimized instance featuring high memory density, dedicated physical cores, and local NVMe SSD storage for data-intensive workloads.
Amazon Web Services x2gd.12xlarge is an ARM64 memory-optimized instance featuring 48 dedicated physical cores powered by the AWS Graviton2 processor running at 2.5 GHz. It is provisioned with 768.0 GB of RAM, offering a high 16:1 memory-to-vCPU ratio, alongside 2850 GB of local NVMe SSD instance storage and 20 Gbps baseline network bandwidth. Benchmarks show strong multi-core CPU performance, though single-core execution and memory latency present performance tradeoffs. The instance provides high resource density and cost efficiency for memory-intensive workloads. It is best suited for large-scale databases, caching layers, and in-memory analytics.
