The Cray X1 relies on Samsung’s RDRAM for its extreme memory performance. With an aggregate memory bandwidth of 6.4GB/s, the four-channel RDRAM module provides the highest performance memory currently on the market.
The Cray X1 is designed to drive advances in aerospace and automotive engineering, national security, and weather and climate prediction. The Cray X1 scales to more than 52 trillions of peak calculations per second (teraflops) compared to 40teraflops of NEC's Earth Simulator, and is designed to be substantially faster on real-world problems than competing systems. Customers for the Cray X1 will include government, academic institutions and industry. More information about Cray’s X1 supercomputer is available in this document.
