A12 chip could be 20% faster and consume 40% less power

Earlier, we commented on the rumors of the new iPhones released by Bloomberg, including the iPhone X's successor to be powered by Apple's newest chip, the “A12”. While the trade name may not just be “A12” (considering the nomenclatures adopted by Ma in recent years, such as A10 Fusion and A11 Bionic), Macworld You have already placed your bets on the possible features of this processor.

Firstly, the A12 produced by Taiwan Semiconductor Manufacturing Company (TSMC) be the first Apple chip to use the 7-nanometer production process. This means, based on the 10nm process by which the A11 was manufactured, that the 7nm chip will offer 1.6x higher logical density, up to 20% higher speed and up to 40% lower power consumption as stated in the Product Guide. 7nm TSMC chips.

Thus, if Apple (re) produced exactly the same A11 Bionic chip, however by the 7nm process, it could be 40% smaller and reduce power consumption by as much as even 20% faster. However, as the A12 is a new chip (and not just a shrunken Bionic A11), we can expect even better results from these estimates. Macworld, the A12 has between 5.5 and 6 billion transistors versus 4.3 billion A11 Bionic.

The site also assumes that the A12 will continue with two high-performance cores (such as the Bionic A11 chip, which operates at a maximum speed of 2.39GHz), but will utilize a higher transistor count to improve performance and efficiency. In this sense, it is not expected a very large jump in the speed of the clock from the A12 which, despite being powerful, probably does not have enough space to exceed 2.5GHz (considering a device the size of iPhone X).

Geekbench Single Core Score (single-core)

Looking at the Geekbench results for single-core iPhones, you can see that the performance improvement has grown almost linearly over the last four generations of devices, a trend that should remain in line with estimates of Macworld. Also according to them, the Geekbench score for single-core of an iPhone equipped with the A12 should revolve around 5,000 points about 800 points more than the A11 Bionic.

Geekbench Multi-Core Score (multi-core)

As we said, the forecast of the Macworld The A12 has a similar architecture to the A11 Bionic chip (2 larger cores and 4 smaller cores), but with even greater efficiency. Based on the same analysis as for the single core test, the site calculated that the A12 multiple core score would be 15,000 points, against 10,174 from the previous generation but they don't expect this to really happen unless Apple introduces a third generation performance controller with the new chip.

Therefore, understanding that Apple keeps the second generation controller (introduced with the A11 Bionic) on its new chip, the Macworld expects a 25 to 30 percent improvement in performance multi-core gives us a Geekbench score in the range of 13,000.

Graphic performance and machine learning

With respect to the graphics processor, Apple may at this point make a slight change in the architecture of its chip (compared to the A11 Bionic) and add a fourth core to improve A12 graphics performance by up to 40%. In addition, the new processor may have faster RAM. However, unless Apple adds more memory channels to enhance bandwidth of the chip, it does not provide a gigantic increase in gaming performance.

The A11 Bionic was the first Apple chip to feature dedicated machine learning hardware, the so-called Neural engine. On the iPhone X, this processor is capable of 600 billion operations per second, and considering Apple's machine-learning fanaticism, it is likely to invest more heavily in this type of hardware whether this year's iPhones or not. To the Macworldit would be surprising if the Neural engine of the A12 would be capable of at least 1 operation rail per second, or then 1.2 rail twice the learning power of its predecessor.

Drums

Last but not least is the battery; Considering only the change of the manufacturing process from 10nm to 7nm, it would be possible that the next flagship had better battery life. However, as we know that the A12 is an even more powerful chip, part of this 40% reduction in power can be used for another device task such as the Neural engine. In addition, this duration is the result of a number of factors that can vary even between devices, such as cellular and Wi-Fi network efficiency, display, storage, etc.

THE Macworld estimated that while the battery life during use remains the same, the device's resting time is much longer and that an even larger battery in the supposed “iPhone X Plus” gives a real advantage over the iPhone's successor. X, obviously.
