What's the real improvement of iPhone 12?

On October 14, 2020, Apple's postponed launch finally released its new iPhone 12 of the year. Compared with previous iPhones, this generation of iPhones fully uses the super retina XDR OLED screen, with a pixel density of 460 PPI and a return to the style of iPhone 4.

In addition to the traditional processor upgrade, the iPhone 12 supports 5g, including screen, appearance, camera and so on.

For the sake of publicity, apple listed a lot of innovations, but the real innovation is not so much improved. Compared with the previous products, where is the real progress of the iPhone 12? Let's take a look.

The truth of A14 processor

The iPhone 12 series is equipped with A14 bionic chip, 5nm production process and 1.18 billion transistors. According to apple, the performance of the iPhone 12 series is 40% higher than that of the A13.

In fact, this processor is already in use on tablets. Compared with A13, A12 and a11, the big core of A14 processor is not improved greatly. It mainly depends on the technological progress and the pulling frequency to improve the performance.

The single thread performance of A14 processor is better than that of A13 processor, but this improvement is based on 3GHz to 2.66GHz, and the actual IPC improvement is very small.

Apple's A-Series processors are also squeezing toothpaste, and the previous generation of IPC has doubled.

However, it is worth noting that the small core of Apple A14 has been significantly improved. The small core of Apple A14 comes from the core technology of Apple A6. After years of improvement, the performance and power consumption ratio of this small core is very excellent.

Apple has further strengthened the small core this time, hoping that the main daily applications will run on this small core. The less chance to use the big core, the better the power consumption of the whole machine.

In terms of GPU, Apple has strengthened it. Apple claims to be a console level performance. In fact, this game console is about the game console many years ago, which can't be compared with the latest ps5. Apple's more reinforcement is in AI. Apple has doubled its neural engine to 16 cores, which can perform 11 trillion operations per second. This computing power can cooperate with software to do some real-time AI processing.

Apple's additional transistors are mainly used in AI.

Progress and defects of screen

This time, Apple has completely upgraded the OLED screen, which is equivalent to popularizing the former high-end OLED screen to all products.

OLED has the inherent contrast, the advantage of gamut is not much to say, the resolution advantage and the arrangement of some relations, seemingly very high, the actual progress may not be great. An added benefit of OLED is that the iPhone has a smaller frame and a 6.1-inch screen. The iPhone 12 is 4mm narrower than the iPhone 11, which makes the iPhone 12 lighter and more portable.

What's interesting is that Corning's new material, ceramic shield, is a transparent ceramic like material that is stronger than glass, giving the new iPhone a harder front and back glass than any smartphone. The anti fall performance is four times that of the past.

The defect of Apple's screen is that it doesn't use 90hz or 120Hz. There is a big difference between 60Hz and 90hz. Apple may be for endurance, but in terms of experience, there is an essential gap between above 90hz and 60Hz. This is a pity. I hope the next generation of Apple products can make up for it.

Camera and 5g

Although apple is still 12 million pixels this time, it has updated the size of the camera. In addition to the conventional improvements of seven lens modules, the main reason is to increase the area of CMOS.

Apple's increase in unit pixels to 1.7 microns means Apple's CMOS area is 1/1.88 inches, between the current mainstream 48 million and 64 million CMOS.

Larger area and constant pixels further improve the performance of low light, but the resolution is still weak.

Apple has greatly improved its AI capability this time, and may make great progress in computational photography.

In terms of 5g, Apple has used the baseband of Qualcomm to support all 5g bands, but it has removed millimeter wave support in China because it does not.

It needs to be said that Apple supports the 5g band of n28 radio and television. At present, there are not many 5g mobile phones in China.

In the future, radio and television 5g has put 192 segment, and apple mobile phone can be used directly.

More and more profitable apples

Apple has canceled headphones and chargers for environmental reasons. But with the addition of magnetic suction, it looks like apple is selling its own wireless charging device. It's like apple canceling the headset and promoting Bluetooth headset.

This time, Apple has also introduced the official accessories of magnetic suction, which are all high price products. A card bag costs 399 yuan. This kind of product with high profit margin is a sharp tool to attract money.

Users buy 10000 yuan mobile phones, naturally want to be different, by the way, to buy a 399 yuan magnetic card packaging card is also logical. Apple made money.

Apple is becoming smarter and smarter to make money with accessories that look different.

Apple's iPhone 12 is tempting for users, but patient users can wait for the 2021 Apple se 5.5-inch version.

Since 2020, it has been rumored that Apple will come up with an iPhone SE version that looks like the iPhone 8 plus, with the latest processor, but only single shot, unlocked with a positive fingerprint, and the price will be cheaper.

If Apple can come up with a 5.5-inch version of the iPhone Se in 2022, with A14 processor, 5g support, single shot, LCD screen, front fingerprint unlock, and a new 1 / 1.88-inch 12 million main camera, it would be great.
