The complexity of the project contributed to the setback. The Blackwell computer involved seven new chip designs that needed to be developed and put into production simultaneously, according to Huang. The problems first surfaced in August, when Nvidia's stock fell around 8% after a report that Blackwell's production was delayed due to a design flaw, possibly setting deliveries back by three or so months and impacting major customers such as Google (GOOGL-0.48%) and Microsoft (MSFT+0.31%). During the company's second-quarter earnings that month, Huang said Nvidia shipped samples of Blackwell to customers and that the AI platform's production would ramp up in the fourth quarter into the next fiscal year. To "improve production yield," Nvidia made a change to Blackwell's GPU mask, the chipmaker said during earnings. However, "there were no functional changes necessary," Huang said on a call with analysts. The company said it expects to "ship several billion dollars in Blackwell revenue" in the fourth quarter.
