What were the processors of the iphone in the past?

Apple officially released A4 chip on 2065438+0065438+1October 27th, which is called Apple's first work. It uses a 45nm single-core processor and 800 MHz ARM Cortex-A8.

At the same frequency, the performance of A4 chip is better than that of Samsung S5PC 1 10, but its core structure is very similar to the Samsung processor used before, only the main frequency is increased, so A4 chip is not the real achievement of Apple, but it lays the foundation for Apple to realize real self-research.

2, A5 and A6

A5 is Apple's first dual-core processor, which was released in Jobs' traditional iPhone 4S. It has higher computing power and lower power consumption.

Apple A6 is a processor released by Apple 20 12. This processor is designed by Apple and assembled by Samsung. It is a dual-core processor with ARM architecture. It adopts the instruction set of ARMv7-A, and its performance is between Cortex-A9 and Cortex-A 15, which is better than that of Qualcomm Krait 300.

It is worth mentioning that Apple A6 is only a dual-core processor, while iPhone 5 equipped with A6 has trampled on many Android machines with quad-core processors on the running score list. Apple has also proved to many enthusiasts that the performance of a processor can't just look at the number of cores.

3、A7

For Apple and enthusiasts, A7 can definitely be called God U, which opens the door to the 64-bit era for mobile phone processors and has great epoch-making significance. A7 was launched on the iPhone 5s. It adopts a brand-new 64-bit design, uses the 64-bit instruction set of ARM-V8, adopts its own Cyclone architecture, adopts 28nm technology, and the main frequency is 1.3GHz.

With this powerful processor, the iPhone 5s has become one of Apple's most classic models. It supports upgrading to iOS 12. At present, I can still run mainstream software smoothly with iPhone 5s, and it's no problem to watch videos and web pages.

4, A8 and A9

A8 processor is the second generation 64-bit mobile phone processor developed by Apple. Cyclone architecture is still adopted, and the main frequency parameter is raised to 1.4GHz. This processor is used on iPhone 6 and iPhone 6 Plus released in June 20 14.

The A9 processor is the third generation dual-core 64-bit mobile processor, which adopts TSMC 16nm technology/Samsung 14nm technology, and is used for iPhone 6s, iPhone 6s Plus and iPhone SE.

5、A 10

A 10 processor is Apple's first quad-core processor with 64-bit design, with 3.3 billion transistors. Because A 10 processor has two high performance cores and two high energy efficiency cores, it is not a true quad-core processor.

Of course, its performance is still strong, and its comprehensive experience is not worse than that of Android equipped with Qualcomm Snapdragon 845. Apple also claims that the A 10 processor has reached the performance of the host level.

6、A 1 1

On A 1 1, Apple's self-research strength stands out. Its CPU, GPU, performance controller and neural network engine are all independently developed by Apple. This processor was first used on iPhone 8, iPhone 8 Plus and iPhone X.

A 1 1 bionic chip not only has powerful performance (A 1 1 single core running score of 4200, multi-core running score 10000, which is more than 55%/kloc-0 than Xiaolong 835 single core and multi-core running score. Its neural network engine adopts dual-core technology, and the maximum number of operations per second can reach 600 billion!

7.A 12 and A 13

A 12 is a six-core bionic chip released on 20 18, which was first used in three models: iPhone XS, iPhone XS Max and iPhone XR. 7nm process technology is adopted, and the CPU part adopts self-developed fusion architecture. Compared with the previous A 1 1, the performance is improved by 15% and the power consumption is reduced by 50%.

A 13 is a bionic chip released in September 20 19. It was first applied to iPhone 1 1, iPhone 1 1 Pro, iPhone1/pro max.

It adopts TSMC's upgraded 7 nm process and integrates 8.5 billion transistors. The CPU is designed as six cores, and the GPU is designed as four cores. At the same time, A 13 also has an 8-core neurocomputing engine, which improves performance by 20% and reduces power consumption by 15%.
