The iPhone 12 hasn't been released yet. Someone has already released the A14 in advanceTrue appearance。 Recently,The blogger of station B released the upper cover of A14 chip in advance and made some display. From the chip comparison, A14 is slightly smaller than A13, and the word "096 2015" is also printed on the chip, which may mean that the A14 chip was produced in April this year.
Prior to this, A14 chip spy photos appeared on the Internet, the number of which shows that the production time is the 16th week of 2020, that is, in April this year, the date is about the same asored chip production time.
According to TSMC's official data, compared with 7Nm (the first generation DUV), the new 5nm chip based on cortex A72 core can provide 1.8 times the logic density, increase the speed by 15%, or reduce the power consumption by 30%. The SRAM in the same process is also excellent with reduced area.
In other words, A14 is at least 15% faster than A13 in performance, which is only theoretical data.
Earlier, there were netizens who exposed getting up earlyAppleA14 Geekbench score ,1509 points ,4047 points, as a control is A13 1339 points ,3571 points. Thus, compared with A14 A13 there is great progress and improvement.
In addition, Apple will upgrade the AI module of A14, and the execution efficiency of machine learning is about twice that of A13.
