AMD CEO Lisa Su said chip shortages will persist for the rest of the year, but the company was able to improve supply enough to beat revenue expectations in the second quarter, where the company nearly doubled its sales from the same period last year — a near repeat of the first quarter. “We are making progress each quarter [on supply], and we made progress in the second quarter. That enabled us to exceed the original guidance,” she said during AMD’s quarterly earnings call Tuesday. “And as we go into the second half of the year, we’re continuing to bring on extra supply each quarter,” which contributed to the company raising its guidance for full-year revenue growth by 10 points.
