Mactracker und EveryMac schreiben, dass das Modell bis auf den Prozessor identisch ist …

Mactracker [mactracker.ca]:
"On June 5, 2017, at the Worldwide Developers Conference (WWDC), Apple updated the MacBook Air with a small processor speed bump. The default configuration now includes a 1.8 GHz processor rather than 1.6 GHz."

Bei EveryMac.com [everymac.com] werden die beiden Modell gemeinsam gelistet [everymac.com] und folgendes angemerkt:
"On June 5, 2017, Apple quietly updated the MacBook Air 'Core i5' 1.6 13" (Early 2015) with a modestly faster 14-nm 'Broadwell ULT' 1.8 GHz Intel 'Core i5' processor (5350U). This model otherwise is identical to late configurations of its predecessor apart from some identifiers."
