Intel has often prioritized margins at the expense of its customers to prevent their most efficient chips from falling in price. In the case of AMD, they do not have much problem in reducing their margins in order to increase sales volume. With this Microsoft could develop cheaper devices and give a touch of attention to Intel. It is said that the company could be considering the AMD Picasso for its Surface of 2019. The next one is going to be a good year for the processor market, with the arrival of the Zen 2 of 7 nm and the processors of 10 nm of Intel.
