SPARC T3
The SPARC T3 microprocessor (previously known as UltraSPARC T3, codenamed Rainbow Falls, and also known as UltraSPARC KT or Niagara-3 during development) is a multithreading, multi-core CPU produced by Oracle Corporation (previously Sun Microsystems). Officially launched on 20 September 2010, it is a member of the SPARC family, and the successor to the UltraSPARC T2.
Performance
Overall single socket and multi-socket throughput increased with the T3 processor in systems, providing superior throughput with half the CPU socket requirements to its predecessor.
The throughput (SPEC CINT2006 rate) increased in single a socket T3-1 platform in comparison to its predecessor T2+ processor in a dual-socket T5240 platform.
Under simulated web serving workloads, dual-socket based SPARC T3 systems benchmarked better performance than quad-socket(previous generation) UltraSPARC T2+ systems (as well as competing dual and quad socket contemporary systems.)
History
Online IT publication The Register incorrectly reported in June 2008 that the microprocessor would have 16 cores, each with 16 threads. In September 2009 they published a roadmap that instead showed 8 threads per core. During the Hot Chips 21 conference Sun revealed the chip has a total of 16 cores and 128 threads.
