The UltraSPARC™-II CPU is the second generation in the UltraSPARC™ s-series microprocessor family.
A complete implementation of the SPARC



V9 architecture, it has binary compatibility with all previous ver-

sions of the SPARC™ microprocessor family

.

The UltraSPARC™-II CPU is designed as a cost effective, scalable and reliable solution for high-end worksta-
tions and servers. Meeting the demands of mission critical enterprise computing, theUltraSPARC™-II CPU
runs enterprise applications requiring high data throughput. It is characterized by a high integer and floating
point performance: optimally accelerating application performance, especially multimedia applications.

Delivering high memory bandwidth, media processing and raw compute performance, the UltraSPARC™-II
CPU incorporates innovative technologies which lower the cost of ownership.
