Custom Silicon List

Custom AI chip design partners

Most custom AI chips are a two-company job: the owner sets the architecture and an ASIC partner turns it into silicon. In this list, Broadcom is named on 11 chips, Alchip on 1, Marvell on 1, MediaTek on 1, and 17 are designed in-house. Each partner links to the source that states it, and a partner that rests on press reporting names the outlet.
