Intel says the production of its next-generation chips will be set back until 2022, following years of delays getting its current-generation chips on sale.
The company said it was exploring “contingency plans” such as having third-party manufacturers produce some of its products.
In June, Apple said it would transition its Mac computers away from Intel processors and design its own chips.
One expert said Intel risked leaving a gap for competitors to step into.
Intel said it had identified a “defect” in its manufacturing process that led to the new delay.
