UltraSPARC T1, T2, and T2 Plus Processors

by Karen Perkins, last updated on 2009-08-26

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).

The UltraSPARC T2 Plus processor, which is available only in Sun servers, extends these features by replacing the networking functionality with coherency links, enabling multi-socket system designs. Both processors benefit from tight integration with the Solaris OS and with Sun's latest virtualization technologies.

The UltraSPARC T2 and T2 Plus Processors web page provides information about features and benefits, links to datasheets, and resources, such as:
