• AWS News Blog Amazon EC2 X8i instances powered by custom Intel Xeon 6 processors are generally available for memory-intensive workloads | 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 3.3 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.
Article Summaries:
- Amazon has announced that its new EC2 X8i instances-powered by custom Intel Xeon 6 processors-are now generally available. Designed for memory‑intensive workloads such as SAP HANA, large databases, analytics, and EDA, the X8i offers up to 6 TB of memory, 1.5 × the capacity and 3.3 × the bandwidth of the previous X2i generation. Customers report up to 43 % higher overall performance, with significant gains in SAP, PostgreSQL, Memcached, and AI inference workloads. The family includes 14 sizes (up to 384 vCPUs) and two bare‑metal options, supporting up to 100 Gbps network bandwidth and flexible IBC scaling.
