The UltraSPARC T2 processor is the industry's first "system on a chip," packing the most cores and threads of any general-purpose processor available, and integrating all the key functions of a server on a single chip: computing, networking, security, and input/output (I/O), plus tight integration with the Solaris operating system.

At A Glance
The UltraSPARC T2 processor is the fastest commodity processor with two world-record single-chip SPEC CPU results, based on tests that delivered 78.3 est. SPECint_rate2006 and 62.3 est. SPECfp_rate2006
Powered by less than 95 watts (nominal) with less than 2 watts per thread, this next generation UltraSPARC T2 processor boasts the most functionality, and lowest wattage per core and thread of any processor in its class
Integrated multithreaded 10 Gb Ethernet networking
Integrated PCI Express I/O expansion
Integrated floating point and cryptographic processing units per core

--------------------------------------------------------------------------------

Key Applications
Single-socket rackmount and blade servers
3G/4G telco infrastructure
WiMAX (Worldwide Interoperability for Microwave Access) infrastructure
Network infrastructure

--------------------------------------------------------------------------------

All SPEC CPU metrics quoted are from full "reportable" runs, but are designated as "estimates" because they used pre-production systems. SPEC, SPECint, SPECfp reg tm of Standard Performance Evaluation Corporation. Results from www.spec.org as of 8/6/07. Sun Ultra SPARC T2 @1.4GHz (64 threads, 8 cores 1 chip) 78.3 est. SPECint_rate2006, 62.3 est. SPECfp_rate2006.

Features and Benefits
With eight cores and 64 threads on one chip, integrated 10 GbE networking, crypto, and PCI-Express expansion, you have the jump on anything else on the market. The opportunities for system consolidation and virtualization are here like never before. Consumes less power per core and thread than any processor in its class – without compromising on performance. The UltraSPARC T2 processor gives OEMs a massively threaded, multi-core alternative to more power-hungry, less threaded processors from competing vendors.

Key Benefits
Higher performance and throughput, more network bandwidth, integrated security, low power consumption
Optimized to run multithreaded applications rapidly, efficiently, and securely
Superior consolidation and virtualization capabilities: Up to 64 domains on a single processor
Leverages Solaris 10, the most advanced OS available
Features and Benefits
Unprecedented Throughput
Revolutionary Multithreaded Networking
Faster I/O Expansion
The Consolidation Processor
"Zero Cost" Security
Advantages for OEMs and Developers



--------------------------------------------------------------------------------

Unprecedented Throughput
Ahead of all the rest
By far, the UltraSPARC T2 processor has the most cores and threads of any processor in its class. It delivers eight cores, while the competition is struggling to get to four. And, it gives you 64 threads today, while the competition struggles to deliver eight.

T2 = Double the Throughput of the UltraSPARC T1 processor
The UltraSPARC T2 doubles the throughput of the UltraSPARC T1 processor, by doubling the threading from 32 to 64. The UltraSPARC T2 is the only processor to scale its performance through threading, rather than by increasing the clock frequency or quadrupling the caches.

Massive Floating Point improvement
By dedicating one Floating Point Unit (FPU) to each core, we were able to improve floating point throughput performance by 10x over the first-generation UltraSPARC T1 processor.

More memory
The UltraSPARC T2 processor offers 33 percent more L2 cache than its predecessor. Four integrated memory controllers are integrated on the processor.

Better performance across your network
Now, more applications than ever can take advantage of Chip Multithreading Technology (CMT) throughput, from huge databases in the heart of the data center to bandwidth-hungry web services at the edge of your network.


--------------------------------------------------------------------------------

Revolutionary Multithreaded Networking
Multithreaded 10 GbE performance
Dual, multithreaded 10 Gb Ethernet, integrated on the UltraSPARC T2 processor, delivers up to 4x the performance of current network interface cards, without the cost of the cards. Multithreaded 10 GbE relieves network overhead, helps eliminate network I/O bottlenecks, enables faster network access, and improves rackmount server performance. Sun is the only company to offer multithreaded 10 GbE.


--------------------------------------------------------------------------------

Faster I/O Expansion
An essential throughput component
Eight lanes of PCI Express I/O expansion is integrated on chip, accelerating I/O-intensive applications, such as OLTP databases, back-up server operations, and streaming media.


--------------------------------------------------------------------------------

The Consolidation Processor
More virtualization flexibility than any processor in its class
The superior compute power and multithreaded 10 GbE networking of the UltraSPARC T2 processor make it especially valuable for consolidation and virtualization projects. For example, by leveraging the unique, no-cost advantages of Solaris Containers, and Logical Domains (LDoms) the UltraSPARC T2 processor lets you run up to 64 domains on one processor. That can help help you completely refactor your network infrastructure while saving thousands of dollars.


--------------------------------------------------------------------------------

"Zero Cost" Security
Integrated crypto onboard
The UltraSPARC T2 processor was designed with one integrated cryptographic unit for each of its eight cores. Integrated cryptographic acceleration means applications can run securely without the extra cost of a separate cryptographic processor, and without the high performance penalty previously associated with secure operation. Sun's integrated cryptographic units support the ten most common ciphers and secure hashing functions, including NSA approved algorithms. And, they outperform competing accelerators by more than 10x, with minimal performance impact.


--------------------------------------------------------------------------------

Advantages for OEMs and Developers
Unique system designs for OEMs
The UltraSPARC T2 processor's massively threaded, multi-core capabilities are an easy choice over the traditional power-hungry, minimally threaded processors from others. It consumes less power per core and thread than any processor in its class–without compromising performance. Its nominal sub-95 watt power draw lets you deliver high-performance solutions even in power-budgeted designs, for example, ATCA blade systems.

Specifications
Imagine: one chip, eight cores, 64 threads. Plus integrated 10 GbE networking, crypto, and PCI-Express expansion. Let's add Solaris 10 to the capabilities, the free and open source OS. We introduced Sun's second generation CMT processor while the rest of the industry is straining to catch up with its first generation.

UltraSPARC T2 不以主频取胜,它的
特点是Core多,省电

也没见省多少电啊.主频上不去才多CORE.

就是以数量取胜

面向市场不同吧！！

属于低性能core，多个core加起来提高性能。但这个core一多，软件的LICENSE就麻烦了，而且管理也有些麻烦。

是买的一家做网络产品的COU的技术。网络产品的CPU一般都是简单专用CPU。
