Restructuring efforts are paying off for AMD as the PC market transitions to mobile.

Go ahead and fire up Survivor by Destiny's Child and fast forward to the chorus, as there may not be a more appropriate string of lyrics to describe the attitude at Advanced Micro Devices (AMD). With the PC market making a mad dash towards mobile devices and system sales down in general, AMD somehow managed to trim losses in Q1 2013 by about $444 million compared to the same quarter a year ago, beating out expectations in the process.

Compared to a year ago, Nvidia's sales figures are looking mighty strong.

The transition to mobile is barely affecting Nvidia's bottom line, which raked in $1.11 billion last quarter. That's a decrease of 8.1 percent sequentially, but an increase of 16.1 percent year-on-year, the GPU maker said. Furthermore, Nvidia's full year revenue reached a record high of $4.28 billion, jumping more than 7 percent compared to a year ago. Between its GPU and Tegra sales, which grew 7 percent and 90 percent, respectively, from a year ago, Nvidia is firing on all cylinders.

AMD's total revenue for 2012 came to $5.42 billion, down 17 percent year-over-year.

Maybe no other company than Advanced Micro Devices (AMD) is more happy to leave 2012 behind. By the numbers, it was a forgettable year for AMD, which raked in $5.42 billion in revenue for the entire year, or $47.88 billion less than Intel did. That's not a fair comparison, though there's no sugarcoating the declining numbers AMD posted. The Sunnyvale chip maker made $1.16 billion during the fourth quarter of 2012, a decrease of 9 percent compared to the previous quarter, and down 32 percent year-over-year.

PC gaming is alive and well, as evidenced by strong Kepler GPU sales that helped steer Nvidia towards record revenue of $1.20 billion for the third quarter of its fiscal 2013 period ended October 28, 2012. That's a gain of 15.3 percent compared to the previous quarter, and a 12.9 percent improvement versus last year, Nvidia said, adding that its energy efficient Kepler GPU architecture continued to make excellent headway in the market place.
