("Some customers were recently informed by Intel that its most advanced manufacturing processes, which it calls 18a and 16a, were far behind TSMC, a chip industry official briefed on Intel's progress said. TSMC is producing 30 percent of its leading-edge chips, known as 2 nanometer chips, without any flaws, while Intel’s new process produces less than 10 percent of its 18a chips without flaws, the person said")
