Apple is apparently planning to use AMD's Polaris architecture in both its upcoming laptops and desktops, according to a Digital Trends report. Polaris 10 and 11 chips — formerly referred to under the codenames Ellesmere and Baffin — are expected to be used in hardware hitting the market later this year.
Polaris is built on the 14nm FinFET process with some major power efficiency numbers, which is something Apple is always pushing towards. Most likely they’ll pop up in MacBook Pros and iMacs, which could be previewed at June’s Apple Worldwide Developer Conference. AMD is expected launch its Polaris-based family of GPUs at Computex 2016 (May 31-June 4) or E3 2016 (June 14-17).
Chances that this rumor is true (IMHO): 90%. I predict we’ll see Polaris chips in iMacs and MacBook Pros that will roll out something between July and September.
