express and it sounds a bit like pci express right funnily enough it's conceptually similar instead of adding to your computer's functionality with cards that fit into slots ucie builds on a chips functionality with additional chip lits as an example ucie might allow for a system on ship that has an Intel CPU graphics from AMD and a wi-fi radio from qualcomm a security enclave from microsoft and an ai accelerator from google we did see something like this in 2018 when Intel came out with those kaby lake g processors that featured AMD graphics but ucie takes this concept further and also standardizes it that's the important part but hold on systems on a chip are already a thing so what's the point of this modular approach well most current socs are designed as a single monolithic chip which presents some manufacturing disadvantages you see transistors have gotten much smaller which makes our chips perform better and consume less power but as we start hitting the limits of how small we can make them the obvious way to continue improving performance is to make the chips bigger but doing this raises the chances of a manufacturing defect one little tiny defect that will render the entire thing useless so instead of throwing the baby out with the bath water the industry is moving towards smaller chiplets that can be combined after they're manufactured moreover ucie enables
