China has claimed the top spot on the list of the world's supercomputers.
The title has gone to China's Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.
To reach such high speeds the machine draws on more than 7,000 graphics processors and 14,000 Intel chips.
Key Terms to Understand this Story
CPU speeds are dependent upon the
type of instructions being executed: some are hard and some are easy.
FLOPS are hard and, in general, more meaningful than MIPS and MOPS.
