China has unveiled the Tianhe-3 supercomputer, also known as "Xingyi," developed by the National University of Defense Technology. The supercomputer is speculated to be the most powerful machine currently in existence and could surpass the upcoming "El Capitan" supercomputer being developed by Hewlett Packard Enterprise and AMD. The Tianhe-3 is projected to have a peak performance of 2.05 exaflops and a sustained performance of 1.57 exaflops on High Performance LINPACK, making it a significant leap forward in supercomputing technology.

The machine, shrouded in secrecy as expected, features a hybrid device with CPU and accelerator compute, along with three different kinds of memory. This architecture is likened to the AMD "Antares" MI300A CPU-GPU hybrid and is believed to use a chiplet packaging design. The supercomputer's processor, the Matrix-3000 (MT-3000) accelerators, has been highlighted in a recent case study, shedding light on its cutting-edge technology.

The Tianhe-3 is part of a series of supercomputers built by China's National University of Defense Technology, with its predecessors, Tianhe-1 and Tianhe-2, also leaving a significant mark in the supercomputing realm. The new supercomputer is anticipated to support various applications, including high-performance computing, AI large model training, and big data analysis. It aims to enhance the multi-field application services of the National Supercomputing Guangzhou Center, providing assistance to Guangzhou City and Guangdong Province.
