Niagara2 is the second-generation 8-core 64-thread SPARC
processor from Sun Microsystems based on the power-efficient
CMT architecture optimized for Space, Watts (power), and
Performance (SWaP). It integrates the major server functions on
chip, thus reducing system component count, complexity, and
power and hence significantly improving reliability. Niagara2
breaks new ground by doubling the throughput performance
and performance/watt and providing improvement
in floating point throughput performance as compared to its
predecessor, the UltraSPARC T1. The advanced cryptographic
support that it provides at high bandwidth enables running
secure applications at wire speeds. All these features help Niagara2
enable a new generation of power-efficient fully secure
datacenters.
