Use of 65 nm technology allows SPARC64 VII to provide quad cores in almost the same physical space as existing dual core processors. The result is much superior performance and greatly improved cost efficiency.SPARC64 VII has the same outstanding RAS technology heritage found in Fujitsu mainframes systems. With error detection and recovery mechanisms in all processor circuits, systems halts due to processor error can be avoided. In addition some 3400 data validation circuits in the SPARC64 VII processor support SPARC enterprise's high reliability profile.
