There aren't a lot of details, all we know is that Intel is still having issues with supplying its clients with enough processors. The shortages are intensifying again so Intel may be tapping foundries like Samsung to ensure it has enough capacity in the future. Presumably, this will be for low-end parts. This is not a fast solution either as the process nodes from Samsung and Intel aren't compatible with each other. As such, Intel will need to adapt its chip design if it wants to contract Samsung's production capacity.
In her November 20 letter addressed to Intel's customers, executive V-P and GM for sales, marketing, and communications, Michelle Johnston Holthaus, mentioned that in addition to Intel's own manufacturing facilities, the company is roping in "foundries" (third-party silicon fabrication companies) to meet demand. Samsung and TSMC lead the foundry business, followed by the likes of GlobalFoundries, UMC, etc.Source: Pulse News Korea
