A rebound in the PC market aided Intel's earnings earlier this week, but did not help rival Advanced Micro Devices, which recorded a net loss for the second quarter, even as a shift in its business focus to graphics cards and custom chips boosted revenue. AMD reported a net loss of $36 million, an improvement from the $74 million loss reported in the same quarter a year ago. Revenue in its Computing Solutions division, which deals in chips, was $669 million, declining by 20 percent year over year, due to a drop in processor shipments, AMD said in a statement.
