Just before Apple was preparing to release the iPhone 14 series, Tim Higgins of the Wall Street Journal reported that the low-end iPhone 14 and iPhone 14 Plus models will be equipped with the previous generation A15 bionic chip. "Enhanced version", but he did not give detailed parameters.
Macrumors said the improved graphics performance may be the only change to the A15 chip in the iPhone 14 and iPhone 14 Plus, but other parts are no different from the 6-core CPU, and 16-core Neural Engine versions in the iPhone 13 and iPhone 13 Pro.
Apple launched a new generation of A15 bionic chip at this time last year, using 5nm process technology, "killing" the audience with 15 billion transistors, with two large CPU cores and four small CPU cores, with AI computing power Up to 15.8TOPS.
Although the names are all A15, Apple, which is "skillful", directly divides the A15 chip into several different versions, which are used for iPad mini6, iPhone 13 / mini, and iPhone 13 Pro / Max.
Overall, the A15 chip is equipped with a new 6-core CPU in terms of CPU, including 2 performance cores and 4 energy efficiency cores. Among them, the A15 of the ordinary iPhone 13 has one less GPU core than the A15 chip on the Pro, and the performance is slightly insufficient.
In addition, the difference between the A15 in the Apple iPad mini 6 is that the CPU frequency is slightly lower, and the GPU performance is not limited. According to Ming-Chi Kuo's report in March, Apple's only iPhone 14 Pro models this year will be upgraded to Apple's latest A16 chip, enabling faster CPU performance and, incidentally, making the differentiation between standard and Pro models more pronounced. Of course, the two versions may also be called A16 and A16 Pro, because the naming is not important at all.
Apple is expected to launch four iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max at a press conference at the Steve Jobs Theater tomorrow morning, with the Pro model expected to have many exclusive new features, while the regular Model RAM has been upgraded.
