Since a preview launch at AWS re:Invent 2025, we’re announcing the general availability of new memory-optimized Amazon Elastic Compute Cloud (Amazon EC2) X8i instances. These instances are powered by custom Intel Xeon 6 processors with a sustained all-core turbo frequency of 3.9 GHz, available only on AWS. These SAP certified instances deliver the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud.
X8i instances are ideal for memory-intensive workloads including in-memory databases such as SAP HANA,traditional large-scale databases,data analytics,and electronic design automation (EDA),which require high compute performance and a large memory footprint.
These instances provide 1.5 times more memory capacity (up to 6 TB), and 3.4 times more memory bandwidth compared to previous generation X2i instances.These instances offer up to 43% higher performance compared to X2i instances, with higher gains on some of the real-world workloads. They deliver up to 50% higher SAP Application Performance Standard (SAPS) performance, up to 47% faster PostgreSQL performance, up to 88% faster Memcached performance, and up to 46% faster AI inference performance.
During the preview, customers like RISE with SAP utilized up to 6 TB of memory capacity with 50% higher compute performance compared to X2i instances. This enabled faster transaction processing and improved query response times for SAP HANA workloads. orion reduced the number of active cores on X8i instances compared to X2idn instances while maintaining performance thresholds,cutting SQL Server licensing costs by 50%.
X8i instances
X8i instances are available in 14 sizes including three la
| x8i.2xlarge | 8 | 128 | Up to 15 | Up to 10 |
| x8i.4xlarge | 16 | 256 | Up to 15 | up to 10 |
| x8i.8xlarge | 32 | 512 | 15 | 10 |
| x8i.12xlarge | 48 | 768 | 22.5 | 15 |
| x8i.16xlarge | 64 | 1024 | 30 | 20 |
X8i instances support the instance bandwidth configuration (IBC) feature like other eighth-generation instances.
