Abstract :
The Dawning 6000 supercomputer, which Chinese researchers expect to unveil in the third quarter of 2011, will have something quite different under its hood. Unlike its forerunners, which employed American-born chips, this machine will harness the country´s homegrown high-end processor, the Godson-3B. With a peak frequency of 1.05 gigahertz, the Godson is slower than its competitors´ wares, at least one of which operates at more than 5 GHz, but the chip still turns heads with its record-breaking energy efficiency. It can execute 128 billion floatingpoint operations per second using just 40 watts-double or more the performance per watt of competitors.
