Google ( GOOG) was among a number of tech stocks moving on fresh financials after the bell Thursday.

The Internet search giant reported surging non-GAAP third-quarter income of $1.24 billion, or $3.91 a share, that beat Street estimates by 13 cents a share. Shares of the Mountain View, Calif., company rose $7.38, or 1.2%, to $647, after some choppy trading.

Advanced Micro Devices ( AMD), a chipmaker based in Sunnyvale, Calif., swung to a loss of $396 million, or 71 cents a share, from a year-ago profit. Excluding 22 cents a share in one-off charges, however, results bested Thomson Financial's analyst estimates for a loss of 62 cents a share. AMD stock was up 0.6% to $14.64.

Fellow chipmaker Xilinx ( XLNX) reported third-quarter earnings of 30 cents a share, a penny over targets. Shares ticked up 0.7%. Semiconductor-equipment maker Cree ( CREE) and business-software company Informatica ( INFA) each beat by 2 cents. Shares were up 5.2% and 3.6%, respectively.

Out of the tech sector, Intuitive Surgical ( ISRG) climbed 5.2% after third-quarter income more than doubled from last year to $40.9 million, or $1.04 a share, on better-than-expected revenue of $156.9 million. Shares were trading at $269.89.

And PMC-Sierra ( PMCS) saw mixed trading on two pieces of news. The Santa Clara, Calif., chipmaker said it made $19.1 million, or 9 cents a share, on a non-GAAP basis, which topped per-share targets by 3 cents. In addition, CEO Bob Bailey will retire the post as soon as a replacement is found. He'll serve as chairman of the board through his current term.

PMC shares were recently down 2.1% to $8.84.
