Sun has been touting the efficiency of servers using its first-generation UltraSparc T1 'Niagara' processor, but it's promising
greater gains with the chip's sequel. The first Niagara consumes about 70 watts running flat out. Sun now thinks Niagara 2 will consume between 70 and 80 watts, John Fowler, executive vice president of systems, said in a meeting with reporters at Sun offices here Tuesday. Although that power consumption is 'just a teeny bit above Niagara 1', Fowler said, the newer chip absorbs several functions that today require separate electronics and also can handle 64 simultaneous instruction sequences, called threads - twice that of Niagara 1.
