According to a report by the Financial Times, China has banned the use of Intel and AMD chips in government computers. The decision, which aims to reduce reliance on foreign technology and boost domestic semiconductor production, is expected to have far-reaching implications for the global tech industry and geopolitical relations. The Chinese government has instructed PC suppliers to replace foreign-made CPUs with domestic alternatives in all government computers within the next two years. This directive is part of China's broader strategy to achieve self-sufficiency in critical technologies and reduce its vulnerability to potential supply chain disruptions or geopolitical tensions. The ban on Intel and AMD chips is likely to significantly impact the two companies, as China represents a substantial market for their products.

However, the move also presents an opportunity for Chinese semiconductor manufacturers like Loongson and Sunway to expand their market share and accelerate the development of their next-generation chip technologies. By reducing its dependence on foreign technology, China aims to strengthen its position in the global tech landscape and mitigate the risks associated with potential sanctions or export controls. As China pushes for self-sufficiency in semiconductors, the global technology industry will likely experience a shift in supply chains and increased competition from Chinese manufacturers. This development may also prompt other countries to reevaluate their reliance on foreign technology and invest in domestic production capabilities, potentially leading to a more fragmented and competitive global tech market.

The Exascale supercomputer arms race is making everyone invest their resources into trying to achieve the number one spot. Some countries, like China, actively participate in the race with little proof of their work, leaving the high-performance computing (HPC) community wondering about Chinese efforts on exascale systems. Today, we have some information regarding the next-generation Sunway system, which is supposed to be China's first exascale supercomputer. Replacing the Sunway TaihuLight, the next-generation Sunway will reportedly boast over 40 million cores in its system. The information comes from an upcoming presentation for Supercomputing 2023 show in Denver, happening from November 12 to November 17.

The presentation talks about 5 ExaFLOPS in the HPL-MxP benchmark with linear scalability on the 40-million-core Sunway supercomputer. The HPL-MxP benchmark is a mixed precision HPC benchmark made to test the system's capability in regular HPC workloads that require 64-bit precision and AI workloads that require 32-bit precision. Supposedly, the next-generation Sunway system can output 5 ExaFLOPS with linear scaling on its 40-million-core system. What are those cores? We are not sure. The last-generation Sunway TaihuLight used SW26010 manycore 64-bit RISC processors based on the Sunway architecture, each with 260 cores. There were 40,960 SW26010 CPUs in the system for a total of 10,649,600 cores, which means that the next-generation Sunway system is more than four times more powerful from a core-count perspective. We expect some uArch and semiconductor node improvements as well.
