It was reported earlier that Apple will equip the upgraded iPad Pro tablet with a14x bionic chip, and it is expected to adopt TSMC’s 5nm process, which will leave a deep impression on the energy efficiency index. Recently, YouTube tech blogger @ lukemiani shared some leaked data on twitter, highlighting the performance improvement of a14x bionic chip, saying it could almost compete with Intel Core i9-9880h (a powerful eight core chip). < / P > < p > depending on the usage scenarios, Apple needs to equip the 16 inch MacBook Pro notebook with a large heat dissipation module to guarantee the performance of Intel Core i9-9880h processor. By contrast, the energy efficiency performance of a14x is more impressive. < p > < p > in fact, the performance of a12x bionic chip used in 2018 iPad pro in some benchmark projects is already equivalent to the 15 inch MacBook Pro equipped with Intel six core processor. < / P > < p > therefore, thanks to the improvement of chip manufacturing process, lukemiani’s disclosure of a14x bionic is still quite reliable. < / P > < p > at the same time, the A14 (without X-tail) chip for the upcoming iPhone 12 series of smartphones is only slightly slower than the a12x bionic. Despite earlier revelations that the new chip will be faster. < / P > < p > in any case, the performance level of such a lightweight device was unimaginable a few years ago. With the official release of A14 / a14x bionic chip, the market may face more fierce competition.
