The National Supercomputing Center in Guangzhou, China, has unveiled a new domestically-developed supercomputer, the Tianhe Xingyi.
Performance benchmarks were not revealed, but Chinese state news agency Xinhua said that it outperforms Tianhe-2 (TH-2). Accelerators were not mentioned, just CPUs.
Tianhe-2 is believed to have a peak performance of 100 petaflops, with a sustained performance of 61.44 petaflops after a 2018 upgrade. Tianhe Xingyi is said to double its performance.
With China no longer reporting Linpack benchmark results or taking part in the Top500 competition, reliable performance figures are hard to come by.
The Tianhe-3 supercomputer has not been officially announced, but is believed to be an exascale system.
In 2021, Asian Technology Information Program founder David Kahaner said that the TH-3 system was based on Phytium 2000+ FTP Arm chip plus a Matrix 2000+ MTP accelerator and capable of 1.7 exaflops peak/1.3 exaflops sustained, making it the world's most powerful supercomputer (or at least tied with the US' Frontier).
