Chipmaker AMD's technological prowess has been on display lately, putting more price-performance competitive pressure on longtime rival Intel. In March the company launched new Ryzen 7 processors, based on the company's Zen core microarchitecture, targeted toward PC gamers and other high-performance systems.

In January AMD reported that revenue for all of 2016 rose 7 percent to $4.27 billion from $3.99 billion in 2015. The company's loss for the year was $497 million compared with the $660 million loss reported for 2015.
