In 1998 Fujitsu developed the first SPARC64 processor. Called SPARC64 GP it was used in the G7000F family of servers.

In 2002, SPARC64 V, with improved reliability technology inherited from Fujitsu mainframe development, was used in PRIMEPOWER. PRIMEPOWER with SPARC64 V was sold world-wide and grew to become a respected global platform.

In 2007, all SPARC Enterprise models use the latest SPARC V9 architecture processors. SPARC64 VI for M4000 model and above and UltraSPARC T1 for T1000/T2000. Models incorporating the dual core processor SPARC64 VI inherit all the high reliability and availability technologies of SPARC64 V.

SPARC64, the high performance and business continuity focused processor family is accredited by Sun Microsystems through co-development of the SPARC Enterprise family.

Fujitsu continues to develop SPARC64 processors and provide business platforms suited to an even changing business environment.
