The iPhone series chips since iPhone4 have been completely named with a combination of "A" + Arabic numerals.
The first-generation iPhone (iPhone2G) processor is ARM11 with a frequency of 411mhz.
The iPhone3G (second-generation iPhone) processor is also ARM11, with a frequency of 428mhz.
The iPhone 3GS processor is a 600mhz Samsung S5PC100 processor with an ARM cortex-A8 core.
Later model chip names will be named from A4 to A13. In addition to mobile phone chips, there are also A series chips with X suffix and Z (iPad Pro2020) suffix for iPad. However, generally the larger the number, the stronger the performance.
A11 Bionic, A12 Bionic, and A13 Bionic are all SOCs, which integrate CPU (processor), GPU (commonly known as graphics card), NPU (neural network engine), memory, etc. on one chip. The advantage of high integration is that the size is reduced, and the extra space can be used to store other things. This is part of the iPhone's industrial design.
Needless to say, memory, this year's A13 is not bad, not only the capacity is 4GB, the type has also been upgraded from LPDDR4 to LPDDR4X. (According to an American up dismantling review) The bandwidth increased from 17G/s to 20G/s, an increase of 17%. The voltage dropped from 1.1v to 0.6v, and the power consumption was reduced by 40%. This year, in order to increase battery life, the battery was enlarged and power consumption was reduced, which has made many improvements.
The NPU improves several times with each generation, but apart from unlocking and taking photos, its other functions are not obvious.
The following is the key:
CPU:
Single core
A12=A11*113%
A13=A12*112%
Multi-core
A12=A11*110%
A13=A12*118%
GPU:
A12=A11*133%
A13=A12*150%
Apple’s single-core CPU has always been too powerful, beyond the reach of others. A11 is much better than the current major Android flagships. Of course, single-core power consumption is also beyond the reach of others
CPU multi-core is the same as Intel. It squeezes out toothpaste every year and increases by 10%-20% every year. But after all, the foundation is there. The A12 multi-core launched last year is better than the current Android The flagships (Qualcomm 855 and the latest Kirin 990) are still strong. It goes without saying when the A13 will be strong.
The GPU improves by 30%-50% every year, which is very impressive. To compete with You, the GPU is the best. The iPhone’s greatest advantage. Starting from the A9, Apple's GPU has opened up a 50% gap between Qualcomm, Kirin, and Samsung flagships in the same year. Therefore, the biggest advantage of Apple SOC is its powerful graphics card. A strong graphics card means strong gaming performance.
So is A13 the strongest in every aspect? As an aside, Apple does not use its own baseband, but Qualcomm (A11) or Intel (A12, A13) baseband (that is, 4G, Wi-Fi Internet access, and communication modules), so it is not integrated into the SOC. Apple had been using Qualcomm baseband before the A11, and the signal was good. However, due to patent disputes, Apple A12 and A13 switched to Intel's baseband. Qualcomm and Huawei, as major communications companies, of course use their own basebands. The SOC of Huawei Kirin 990 integrates its own 5G baseband.
Mobile GPU ladder chart:
Usually the A-series processors of Apple phones are shipped randomly from the factory. For example, the Apple 8p and Apple processor.
Hello, Apple only has one mobile phone chip, the A series. Last year it was A13, and the year before that was A12. There is no doubt that A13 has better performance than A12, A11, etc.
This is because Apple’s mobile phones have long adhered to the high-end route, so each new generation of phones uses the same generation of A-series chips. In other words, the mid- to low-end market is not within Apple’s plans.
Moreover, all using the same chip can amortize chip costs and further increase profit margins.
But this strategy has now become looser, because iPhone users’ desire to replace their phones has begun to decline year by year since the iPhone 7 series, and the high-end market continues to be impacted by Samsung, Huawei and OnePlus. The iPhone itself The product strength of the company also has limited growth. Therefore, iPhone now also has mid-range products, such as iPhone XR, iPhone 11 and iPhone SE.
But the mission of these cost-effective iPhones is to "attract users to try the iOS system at a lower price, and then upgrade to the flagship version after generating user stickiness." In order to provide a better user experience and better release iOS performance and equipped with flagship chips are also in the question.
More importantly, iPhone is different from Android manufacturers in that it treats a terminal device as a whole, rather than disassembling specific data such as parts, parameters, and refresh frequencies and marketing them separately. They use the entire ecosystem, Apple's corporate culture, iPhone users' pursuits, and the personality of this group to attract you to join them.
The Android camp has a completely different style. They will take apart each part and clearly mark the price, telling you "you will unlock various levels of experience after paying the corresponding price." This is why Android users are always confused about what kind of processor, what kind of screen, and which generation of flash memory can be bought for 3,000 yuan. If they are lucky enough to spend 2,000 yuan to buy parts that are only used in 3,000 yuan, they will want to pick them up. Like everyone shouting "It smells so good!" - Have you ever felt that Android phones have always felt not as high-end as iOS? In fact, manufacturers and users screwed it up together.
The whole series uses the same chip, which to some extent is a reflection of Apple’s unique corporate philosophy: a mobile phone is not a summary of a bunch of parameters, not an assembly of a bunch of parts, it is a mobile phone that allows you to The power to become better and stronger.
Only one series is released a year, only A series, no knife skills
