Chiplets are everywhere now — Apple, AMD, Intel all mix and match dies in a single package. But the glue that holds them together is a mess of proprietary protocols, each with its own licensing and overhead. Lucas and Luna drill into one specific effort to fix that: the Universal Chiplet Interconnect Express, or UCIe, standard. They trace its origins back to 2022, when a handful of companies — Intel, AMD, Arm, and others — agreed to build an open spec. Three years later, adoption is picking up but the challenges remain: physical-layer compatibility, testing, and the basic question of whether the industry can actually agree on one way to talk between chiplets. This episode uses real numbers — like the 25 gigabit-per-second per lane bandwidth target and the 30-plus companies now in the consortium — to show why UCIe matters and where it still falls short. No hype, just the engineering reality behind the promise of mix-and-match chiplets.
