Amazon EC2 X2i Instances
Up to 50% better performance than X1 instances for memory-intensive workloads
Amazon EC2 X2i instances are the next generation of memory-optimized instances delivering improvements in performance, price performance, and cost per GiB of memory compared to previous generation X1 instances. These instances offer a choice of 16:1 or 32:1 ratio of memory to vCPU and are ideal for memory-intensive databases and electronic design automation (EDA) workloads.
X2idn and X2iedn instances are powered by 3rd generation Intel Xeon Scalable processors with an all-core turbo frequency up to 3.5 GHz and deliver up to 50% higher compute price performance than comparable X1 instances. X2idn and X2iedn instances both include up to 3.8 TB of local NVMe SSD storage and up to 100 Gbps of networking bandwidth, while X2idn offers up to 2 TiB of memory and X2iedn offers up to 4 TiB of memory. X2idn and X2iedn instances are SAP-Certified and are a great fit for workloads such as small-to large-scale traditional and in-memory databases, and analytics.

“Siemens EDA helps you engineer a smarter future faster, delivering an unmatched portfolio of electronic design automation (EDA) software, hardware, and services. Siemens EDA worked with AWS to test the new Amazon EC2 X2iezn HPC/EDA focused instances with the industry performance and sign-off leader Calibre evaluating advanced node DRC workloads. We were pleased to demonstrate performance improvements of up to 14% using the 4.5 GHz all core turbo frequency of X2iezn instances for all VMs in the run. Additionally, we successfully demonstrated the use of a heterogeneous server configuration using the X2iezn as the primary node and other lower memory VMs for remote compute - providing an 11% speed up and attractive value. These results confirmed the X2iezn is a good fit for primary server EDA workloads for Calibre Physical and Circuit verification applications.”
