In a surprise move, Intel announced today that it no longer plans to use its own 'Intel 20A' process node with its upcoming Arrow Lake processors for the consumer market. Instead, it will use external nodes, likely from partner TSMC, for all of Arrow Lake's chip components. Intel's only manufacturing responsibilities for the Arrow Lake processors will be packaging the externally manufactured chiplets into the final processor.
