But under former CEO Brian Krzanich, who led Intel from 2013 to 2018, that two-year cycle expanded. Intel's foundry struggled to jump from 14nm to 10nm chips, and that failure caused a CPU shortage that allowed AMD to pull PC makers away from Intel. Under Bob Swan, who succeeded Krzanich after his abrupt resignation, Intel struggled to resolve that shortage, and fumbled its transition from 10nm to 7nm chips.
