Apple’s annual leaps in performance in the iPhone processor seem to stop for the time being: In contrast to previous years, the manufacturer did not make any comparison with the predecessor A14 in the iPhone 12 when it presented the chip called “A15 Bionic”. Instead, Apple only referred to the competition with the introduction of the iPhone 13, the A15 was up to 50 percent faster than the chips of the competition, it said.
A15 against A14
Just like the A14, the A15 is still manufactured in the 5-nanometer construction and apparently relies on a very similar architecture with six processor cores – two high-performance and four energy-saving. The graphics integrated in the SoC (System on Chip) still have four processing cores in the iPhone 13 and 13 mini, but for the first time five in the Pro models. Apple is thus promising “the best graphics performance of all smartphones”.
According to the manufacturer, the Neural Engine, which is designed for machine learning tasks, can now perform 15.8 trillion calculations per second – the A14 has 11. Apple has doubled the system cache of the new chip to 32 MB.
For the new iPad mini 6, which also contains the A15 Bionic, Apple provided a comparison with its own older chip: The CPU is 40 percent faster than in the older A12 chip, the company said. Apple promised this increase in performance last year for the A14 compared to the A12. The beta of Xcode 13 indicates that the iPhone 13 is still equipped with 4 GB of RAM and the Pro models unchanged with 6 GB, how Macrumors reported. Apple has so far not provided any information.
How the A15 Bionic of the iPhone 13, 13 Pro and iPad mini 6 performs in practice – also in comparison to the direct predecessor A14 – Mac & i will deliver a detailed test report of the new devices.
Apple Watch Series 7 probably with S7 chip
So far, Apple has kept a low profile on the processor or system-in-package (SiP) of the Apple Watch Series 7. Apple will According to this one report marketed as the “S7” chip and refer to a 20 percent increase in performance compared to the older S4 / S5 chip – as with the predecessor Series 6 last year. According to developers, the Series 7 CPU has the same name internally as the Series 6 processor.
