Features and Benefits
With eight cores and 64 threads on each chip and integrated features including crypto, I/O, and 10GbE networking, 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 and T2 Plus processors give customers massively threaded,
multi-core alternatives 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

Unprecedented Throughput
Ahead of all the rest
By far, the UltraSPARC T2 and T2 Plus processors have the most cores and threads of any processors in their class. They deliver eight cores and 64 threads per processor, scaling up to 256 threads in four sockets.
T2 and T2 Plus = Double the Throughput of the UltraSPARC T1 processor
The UltraSPARC T2 and T2 Plus double the throughput of the UltraSPARC T1 processor, by doubling the threading from 32 to 64. The UltraSPARC T2 and T2 Plus are the only processors to scale 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 and T2 Plus processors offer 33 percent more L2 cache than their predecessor. Four integrated memory controllers are integrated on the T2 processor. Each T2 Plus processor includes two integrated memory controllers, with next generation SerDes for enhanced performance and increased bandwidth per channel.
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
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 are integrated on each chip, accelerating I/O-intensive applications, such as OLTP databases, back-up server operations, and streaming media. In Sun's multi-socket T2 Plus servers, this bandwidth is multiplied for massive I/O capacity to support your most demanding workloads.
The Consolidation Processor
More virtualization flexibility than any processor in its class
The superior compute power and integrated features of the UltraSPARC T2 and T2 Plus processors 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), you can run up to 64 domains on each processor. That can help help you completely re-factor your network infrastructure while saving thousands of dollars.
"Zero Cost" Security
Integrated crypto on chip
The UltraSPARC T2 and T2 Plus processors were designed with one integrated cryptographic unit for each of the 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.
