Thanks to its new A14 Bionic chip, the iPhone 12 is much faster than any Android phone based on the iPhone 12 benchmarks we've run, but in real-world use it’s a multitasking powerhouse and wipes the floor with older iPhones. 

In a video by EverythingApplePro, the Apple-centric YouTuber compared the iPhone 12 Pro against the iPhone 11 Pro and iPhone Xs, carrying out a variety of tasks. The 12 Pro blew the older models away — and it's not just because of the A14.

EverythingApplePro showed how the iPhone 12 Pro could bounce between a whole load of apps open at the same time. And even after carrying out a video rendering tasks, the YouTuber was able to open up a load of apps in mere seconds. 

That’s thanks to the extra 2GB of RAM the iPhone 12 Pro has over its predecessor, allowing for a lot of apps to be stored ‘in-memory." That means the apps are loaded from the iPhone 12’s RAM rather than its pool of storage. 

This allows for much faster multitasking, something iPhones have struggled with in the past, unlike some Android phones with large amounts of RAM. 

Apple never revealed how much RAM its iPhones have, but it's believed the iPhone 12 Pro has 6GB. Comparatively, the Samsung Galaxy Note 20 Ultra has 12GB. But EverythingApplePro noted that the IPhone 12 Pro shows how a well-optimized chip means there's no need to have vast amounts of RAM in a smartphone. Given Apple designs its chips in-house, it has greater control over how the silicon plays with iOS and the rest of the IPhone. 

In short, the iPhone 12 Pro is not only a powerhouse on the benchmark sheets, but also a multitasking machine in the streets. That alone arguably makes it a compelling upgrade over the iPhone 11 Pro, before you even consider the new design and upgraded cameras.
