Китай создал фотонный чип, заменяющий транзисторы светом — TSMC в шоке

In December 2025, Chinese researchers unveiled LightGen, a chip that processes information with light instead of electrons, packing over 2 million "photonic neurons" and claiming speeds up to 100x faster than a GPU on specific tasks. Headlines are calling it a shock TSMC never saw coming. In this video, Iron Circuit breaks down what China actually built — and why TSMC isn't stunned at all, because it's been building its own competing photonics platform the entire time. We go deep into how photonic computing actually works, China's real parallel efforts (LightGen, Meteor-1, and CHIPX — already shipping real wafers), TSMC's own COUPE technology entering production in 2026, why Nvidia's photonic switches co-developed with TSMC reportedly outperform China's own Fudan University chip, and the honest gap — no domestic customer queue — standing between China's lab achievements and real commercial products. This isn't hype and it isn't dismissal. It's the full, honest comparison: what China genuinely built, what TSMC has been building in parallel, and what to watch next in the race toward photonic computing. 🔔 Subscribe to Iron Circuit for weekly deep dives into the chip war, semiconductor technology, and the engineering battles reshaping global power — before they become mainstream news.
