Graphics-processor maker Nvidia ( NVDA) posted second-quarter results after the close Thursday that were basically in line with the profit warning the company issued in late July. For the second quarter, the company said revenue increased to $427.3 million from $259.9 million in the same quarter a year ago, an increase of 64%. Net income fell to $5.3 million, or 3 cents a share, from $32.9 million, or 19 cents a share, a year ago. On July 30, Nvidia said revenue would be $410 million to $430 million and earnings would be near or above break-even, including a write-down of certain Xbox and nForce chip inventory. Analysts were originally expecting revenue of more than $560 million. Before the company released its earnings, Nvidia announced it had named Marvin Burkett its new chief financial officer. Burkett will take his post in September. He previously served as the CFO of Advanced Micro Devices ( AMD). Mary Dotz had been serving as interim financial chief. Shares of Nvidia rose 67 cents, or 7%, to $10.29 in regular trading. The stock fell to $9.90 in Instinet action after the close.
