Kinngai Chan, analyst at Summit Insights Group, said the problem was that inventories of Nvidia's older gaming chips, based on a technology it calls Pascal, were piling up even as demand for new chips released in August was weaker than expected. Chan also said demand was faltering for Nvidia's chips in data centers, where they are often used for artificial intelligence work such as teaching computers to recognize images.
"But we too are surprised at the below-$3 billion outlook" for the fourth quarter, Chan said.
The trade conflict between the United States and China may also be weighing on Nvidia, analysts said. Tariffs on many Chinese-made goods will rise to 25 per cent starting Jan. 1.
