Researchers harnessed the power of light to create a chip that could perform complex generative tasks with vastly improved energy efficiency.

100 times faster than 5090 ? While also being more efficient?

This thing need deeeper dive, sound too good to be true.

It’s like saying silicon chips being orders of magnitude faster than vacuum tubes sounds too good to be true. Different substrate will have fundamentally different properties from silicon.

Optic computing is as old as the hills. Looking at the abstract, it appears to be the usual domain-specific architecture, which only does very well in a tailored case.

That would be the A100, not the 5090.

From what I can gather, the catch is that this is optical computing, which is up there with quantum computing as things that would be pretty great but good luck making it feasible, let alone mass produce it. You’re not putting one in your home PC anytime soon, but hey, technology moves fast.
