China's Homegrown CPU and Lithography Machine for 7nm Chips Conquer New Heights

What's new on Chips? - August 2, 2023

Editor’s Note:

• China has successfully produced a new high-performance quad-core CPU, the Loongson 3A6000, using their own LoongArch instruction set architecture.

• Shanghai Micro Electronics has developed advanced 28nm immersion lithography machines domestically in China, which are capable of manufacturing 7nm chips through multiple exposures.

Recently, a significant milestone in China's pursuit of independent CPU design has been achieved with the successful production of the new generation quad-core processor, the Loongson 3A6000. This processor, based on the LoongArchitecture, marks a notable advancement in the technological landscape.

The R&D Laboratory of the China Electronics Technology Standardization Institute conducted a comprehensive series of tests on the Loongson 3A6000 quad-core processor. Operating at a frequency of 2.5GHz, the processor demonstrated a single-thread integer/floating point score of 43.1/54.6 in SPEC CPU 2006 base, and a multi-thread integer/floating point score …
