TheSPARC T3microprocessor(previously known asUltraSPARC T3,codenamedRainbow Falls,[1]and also known as UltraSPARC KT orNiagara-3during development) is amultithreading,multi-coreCPUproduced byOracle Corporation(previouslySun Microsystems).[2][3][4]Officially launched on 20 September 2010, it is a member of theSPARCfamily, and the successor to theUltraSPARC T2.[5]

Performance

[edit]

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[6]in comparison to its predecessor T2+ processor in a dual-socket T5240 platform.[7]

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).[8]

History

[edit]
SPARC T3 processor

Online IT publicationThe Registerincorrectly 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.[9]During the Hot Chips 21 conference Sun revealed the chip has a total of 16 cores and 128 threads.[10][11]According to theISSCC2010 presentation:

"A 16-core SPARC SoC processor enables up to 512 threads in a 4-way glueless system to maximize throughput. The 6 MB L2 cache of 461 GB/s and the 308-pin SerDes I/O of 2.4 Tb/s support the required bandwidth. Six clock and four voltage domains, as well as power management and circuit techniques, optimize performance, power, variability and yield trade-offs across the 377mm2die. "[12]

Support for the UltraSPARC T3 was confirmed on July 16, 2010 when the ARCBot under Twitter noted unpublished PSARC/2010/274 which revealed a new "-xtarget value for UltraSPARC T3" being included inOpenSolaris.[13]

During Oracle OpenWorld in San Francisco on September 20, 2010, the processor was officially launched as the "SPARC T3" (dropping the "Ultra" prefix in its name), accompanied by new systems and new reported benchmarks claiming world-record performance.[4]Varied real-world application benchmarks were released with full system disclosures.[14][15][16]Internationally recognized SPEC benchmarks were also released with full system disclosures.[17][18] Oracle disclosed that SPARC T3 was built with a 40 nm process.[19]

Systems

[edit]

With the release of the SPARC T3 chip, the new brand ofOracle SPARC T-series serverswas introduced to the market, effectively replacing CMT (UltraSPARC T2/T2 Plus) machines from the previousSPARC Enterpriseproduct line. Fewer physical products from the former server line were refreshed with the T3 chip, reducing the total number of servers respectively to four:[20]

  • One SocketSPARC T3-12U Rack Server[21]
  • One SocketSPARC T3-1BBlade Server[22]
  • Two SocketSPARC T3-2Server[23]
  • Four SocketSPARC T3-4Server[24]

Virtualization

[edit]

Like the prior T1, T2, and T2+ processors, the T3 supports Hyper-Privileged execution mode. The T3 supports up to 128Oracle VM Server for SPARCdomains (a feature formerly known asLogical Domains).[24]

Performance improvement versus T2 and T2+

[edit]

The SPARC T3 processor is effectively two T2+ processors on a single die.[25]The T3 has:

  • Double the cores (16) of a T2 or T2+
  • Double the 10Gig Ethernet ports (2) over a T2+
  • Double the crypto accelerator cores (16) over a T2 or T2+
  • Crypto engines support more algorithms than the T2 or T2+ including:DES,Triple DES,AES,RC4,SHA-1,SHA256/384/512,Kasumi,Galois Field,MD5,RSA to 2048 key,ECC,CRC32[19]
  • Over 1.9x Cryptography Performance Throughput Increase[26]
  • Faster DDR3 RAM interface over the T2 or T2+ DDR2 interface
  • Double the throughput[21]
  • Double the memory capacity[21]
  • Quadruple the I/O throughput[21]
  • Two PCIe 2.0 eight lane interfaces vs one PCIe former generation eight lane interface[25]
