Tianhe-2 was top of the twice-yearly list that keeps tabs on supercomputer development and growth.
Since the last list, China had 20% more supercomputers in the top 500, while US representation went down 15%.
However, the US still dominates the chart with 233 computers making the latest tally.
China had 76, up from 63 in the last count. This is almost as many as the UK (30), France (27) and Germany (23) combined.
The full list is to be published Monday (today) at a conference in Leipzig, Germany.
