LSI Corp. said this week that the company collaborated with Fujitsu to design the new multi-core SPARC64TM IXfx processor for highly scalable supercomputing applications. The new chip, which features a significant performance boost over the previous generation, couples Fujitsu’s multi-generational expertise in high-performance computing and LSI’s industry-leading custom silicon tech.

 

The SPARC64 IXfx processor is manufactured using 40nm process technology, has 16 high-performance cores, 64KB I/D cache and 12MB shared L2 cache memory to handle the data rate requirements of supercomputing applications. The chip works at 1.848GHz and provides 236.5GFLOPS of double-precision performance while consuming 110W of power. LSI’s custom silicon capability allows storage and networking customers the ability to offer highly differentiated hardware solutions to meet customer demands.
