AMD, Nvidia target substrate capacity amid 4x expansion constraints
What happened
AMD and Nvidia have separately invested in supply-chain capacity expansion, making substrates, packaging, and testing key priorities, which the source attributes to diversifying AI demand. The moves show that chipmakers are extending competition beyond performance and architecture design to control over critical manufacturing resources. Per the headline, they are targeting substrate capacity amid 4x expansion constraints; the body provides no specific expansion size, timeline, or investment amounts, so this reflects disclosed investments/plans rather than completed capacity additions.
