As demand for PC processors plummets, Advanced Micro Devices has borrowed technologies from mobile devices and gaming consoles as a way to perk up sales for its latest A-series laptop processors that were introduced on Tuesday. AMD's latest A-series processors code-named Richland replace existing laptop chips code-named Trinity, which were introduced around the middle of last year. The Richland x86 processors deliver between 20 percent and 40 percent more performance than Trinity chips, AMD has said.
