TSMC’s 5nm node is expected to give Apple’s A14 Bionic a significant boost in both performance and efficiency, turning the upcoming iPhone 12 series into a force to be reckoned with. While it’s not confirmed if the A14 Bionic will use TSMC’s enhanced 5nm node, one tipster believes that the performance jump over the A13 Bionic will be massive. When we say massive, we mean a 40 percent increase in the CPU department.

This 40 percent CPU multi-core performance increase was tweeted by tipster Komiya, who also has some information surrounding the A14 Bionic GPU. According to him, the upcoming SoC’s GPU will be able to deliver a 50 percent performance increase over the A13 Bionic GPU, giving all iPhone 12 models some serious graphical horsepower. Unfortunately, apart from performance differences between the upcoming silicon and the current one, there’s no other info to go on.
