UltraSPARC T2

Sun Microsystems' UltraSPARC T2 microprocessor, is a multithreading, multicore CPU. The UltraSPARC T2's predecessor was the UltraSPARC T1. The chip is sometimes referred to by the codename Niagara II.

The T2 is a derivative of the UltraSPARC series of microprocessors. The processor is available with eight CPU cores, each core is able to handle eight threads concurrently. Thus the processor is capable of processing up to 64 threads concurrently. Also, each core has its own floating-point unit (FPU).

On April 12, 2006, Sun announced the tape-out completion of the T2. It also disclosed that under the same power envelope, the T2 will deliver twice the performance of the T1 when running transactional workload.
