 It incorporates one floating point unit and one dedicated cryptographic unit per core.The cores use the 64-bit SPARC Version 9 architecture running at frequencies between 2.85 GHz and 3.0 GHz, and are built in a 40 nm process with a die size of .An eight core, eight thread per core chip built in a 40 nm process and running at 2.5 GHz was described in Sun Microsystems' processor roadmap of 2009.
