It looks like after Alder Lake in 2H 2021, Intel will be moving to TSMC as its prime partner in mass-producing its next-generation CPU lineup. The press release states that Intel's Core i3 CPUs will be the first mass-production lineup made at TSMC and will be utilizing its 5nm process node. Do note that mass production doesn't exactly means a hard launch and we might end up getting these chips later around 2022. With that said, Alder Lake CPUs will focus on high-performance while utilizing the 10nm Enhanced SuperFin process node.
But Intel plans to shift its entire mid-range and high-performance lineup to TSMC by 2H 2022. The next-generation processors will be featuring the more advanced 3nm process node from TSMC & will be the successors to the Alder Lake lineup. It is not known whether these will be mobility or desktop parts but from the looks of where things are headed, Intel might utilize TSMC for mass production of both segments.
A major shift for Intel giving they're lagging behind AMD and others.
