Same job: moving data. The light just starts closer to the chip.
A simplified picture: the package is real, and the built-in toaster from the reel is only Mochi’s analogy.
Keep this bitPhotonics means using light pulses to move information.
Why care?
Nvidia says moving optics onto the chip’s package, in place of plug-in parts, brings 5x better power efficiency. It says that cuts network power and leaves more for compute. That is Nvidia’s own number, so read it as a seller’s claim.
Where you’ll meet it
Per Ansys, photonics is already the backbone of high-speed internet. The on-package version is for AI data center networking. You never buy or pick one, so the answer for now is not yet.
