The ‌MacBook Air‌ is able to seamlessly open every app with no lag time even as the number of open apps grows. Safari, Maps, Mail, Messages, Keynote, Numbers, Pages, the App Store, Notes, Reminders, and more are all running by the end and the 8GB unified memory in the machine handles it all without an issue. By the end, with every app up and running, App Memory comes in at 3.38GB.

It may be speedy but I am loathe compare the performance of this guy with our new ASUS Tuf Gaming with Ryzen 8 core 16 threads and the NVidia RTX 2080 discrete GPU. That baby is a screamer and honestly, about the same price and around half the price of the 16" MacBook Pro (Intel). Granted the latter has a much better display.
