China's Silicon-Free Chip Just Beat Intel by 40% — The End of an Era?

A Peking University research team has unveiled a transistor built without silicon, using bismuth-based two-dimensional materials called Bi2O2Se and Bi2SeO5. The team reports it outperforms comparable advanced transistors from Intel, TSMC, and Samsung by roughly 40 percent in speed while using less power. This video breaks down what the new material is, how it works, why silicon is running into physical limits, what this could mean for smartphones, AI chips, and data centers, and what still has to happen before this technology reaches mass production. A clear, grounded look at one of the most talked about semiconductor stories coming out of China this year, covering two dimensional materials, transistor physics, the global chip race, and the future beyond Moore's Law.
