SPARC T4
The SPARC T4 is a SPARC multicore microprocessor introduced in 2011 by Oracle Corporation. The processor is designed to offer high multithreaded performance (8 threads per core, with 8 cores per chip), as well as high single threaded performance from the same chip. The chip is the 4th generation processor in the T-Series family. Sun Microsystems brought the first T-Series processor (UltraSPARC T1) to market in 2005.

The chip is the first Sun/Oracle SPARC chip to use dynamic threading and out-of-order execution. 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 403 mm2 (0.625 sq in).
