UltraSPARC T1
Hard Drive Recovery - UltraSPARC T1
UltraSPARC T1 is the first multithreaded and multi-core microprocessor designed by Sun Microsystems. The T1 was known under the development codename ‘Niagara’ until its release on 14 November 2005. It is designed to reduce energy consumption of server computers. This CPU uses only 72 W of power at 1.4 GHz.
UltraSPARC T1 is a ‘new-from-the-ground-up’ SPARC microprocessor implementation that conforms to the UltraSPARC Architecture 2005 specification. It was designed from scratch as a multithreaded special-purpose multiprocessor. It features a whole new architecture designed for greater performance. The design is marked by its ability to run as many concurrent threads as possible, and maximize utilization of each core’s pipeline.
UltraSPARC T1 is available with four, six or eight CPU cores, each core able to handle four threads concurrently. Thus the processor is capable of processing up to 32 threads concurrently. Like the high-end SMP systems from Sun, the UltraSPARC T1 also can be partitioned for running a single or group of processes and/or threads, whilst the other cores deal with the rest of the processes on the system.
At the time of its release, the UltraSPARC T1 server (a single-chip, eight-core, 32-thread, 1.2 GHz UltraSPARC T1 server) performed similarly to a two-socket, four-core, eight-thread, 1.9 GHz IBM POWER5 server and also to a four-socket, eight-core, sixteen-thread 3.0 GHz Intel Xeon “Paxville MP” server. It exceeded the performance of a four-socket, four-core, four-thread 1.6 GHz Intel Itanium server. As a result, the UltraSPARC T1 was considered as the most powerful general-purpose commercial server processors, when considering multithreaded commercial workloads.
