China's Synthetic Diamond Finds Its Biggest Opportunity Yet: Cooling AI Chips

Could a diamond wafer as wide as a basketball be China’s trump card in AI race? (South China Morning Post – June 16, 2026)

https://www.scmp.com/ From wedding gems to supercomputers, China’s giant synthetic diamonds may reshape the global computing competition When Harbin Institute of Technology (HIT) held its 11th group wedding for doctoral students on May 31, each of the 187 newlywed couples was presented with a one-carat diamond ring, with the diamonds grown in the university’s laboratory. The ...

China's Synthetic Diamond Finds Its Biggest Opportunity Yet: Cooling AI Chips

The AI chip industry is hitting a thermal wall. High-end processors now exceed 1,000W thermal design power, with some third-generation semiconductor devices reaching heat flux densities over 500W per square centimeter. To put this in perspective, a chip's heat density can surpass that of a rocket engine nozzle. Without adequate cooling, every 10 degrees Celsius increase in temperature reduces chip performance by 3 to 5 percent and cuts operation…
