A12ai calculation force
The development of single CPU can not meet the needs of practical applications, and the AI era must rely on parallel computing. At present, the mainstream architecture of parallel computing is heterogeneous parallel computing platform. If you need the service of computing power, you can go to the tenth power
Let's first take a look at Qualcomm snapdragon 855
{rrrrrrr}
based on the 7Nm process, the advanced IP design is the steel skeleton, which determines how high the whole building can be. In June this year, arm released a new generation of CPU and GPU architectures with top performance -- custom cortex A76 and mali-g76. Within three months, Huawei took the lead in commercializing these two IP designs. Kirin 980 is developed and commercialized based on cortex-a76 for the first time in the world, with a maximum dominant frequency of 2.6GHz. Compared with the previous generation, Kirin 980's single core performance is improved by 75%, and its energy efficiency is improved by 58%. It injects notebook class performance into smart phones. Kirin 980 takes the lead in integrating al core NPU on mobile phone chips, achieving the highest end side AI computing power in the instry, realizing 4500 images per minute recognition, and the recognition speed is 120% higher than that of the previous generation, which is far higher than that of the same period in the instry; The real-time frame rate of multi person pose estimation is up to 30 FPS, and the human joints and lines can be drawn in real time. Communication performance has always been the traditional advantage of Huawei's mobile phones. Qilin 980 further takes the lead in supporting LTE cat.21 in the world, supports the instry's fastest downlink 1.4gbps rate, and is more flexible to cope with the frequency band combination of different operators in the world
it can be seen how important the CPU chip of a mobile phone is. At present, the most promising high-end chips are apple A12, Huawei Qilin 980, and Qualcomm snapdragon 855. The following editor will teach you their similarities and differences< All of them are high configuration chips that have not been released
Apple A12 chip will match the iPhone released on September 15, so Apple A12 will be released in September. Huawei Qilin 980 was also released at IFA conference in September, but its first mobile phone was Huawei mate 20 in October
because Apple A12 is not suitable for Android, Huawei Kirin only uses Huawei mobile phones, so Qualcomm snapdragon 855 is the first choice for a large number of mobile phone manufacturers. Some people say that Qualcomm snapdragon 855 will meet us with a new thunder snake, and others say that Xiaomi mix 3 and Lenovo Mobile phones. There is no clear news at present
2. The performance battle among the three
Apple A12, snapdragon 855 and Qilin 980 will all be based on 7Nm process, and snapdragon 855 is expected to improve the performance of 845 by 30%. The Kirin 980 will have higher performance than the Kirin 970, with four A76 large cores and four A55 small cores. If it is combined with GPU turbo and CPU turbo technology, it is likely to become the first choice of game console
Apple's A-Series processor does not support Android, but its strength as Apple's Royal chip cannot be underestimated. Apple A12 is built by TSMC, and its performance is 25% higher than a11. It also depends on the running score of snapdragon 855, single core 3033 and multi-core 10992. Kirin ran about 350000, while Apple A12 ran more than 300000
it's not good to just look at the running points. The running points of Apple's A-Series in the past are not too high, but they are easier to use than the chips of the same generation of Android. The surface of the three chips is very fierce. In fact, only snapdragon can be used more widely
among the three high configuration chips, apple A12, Huawei Kirin 980 and Qualcomm snapdragon 855, which chip do you want most
3. Different people's views
"I've never heard of snapdragon beating Kirin, and I've never heard of Apple saying that its own mobile phone has killed other mobile phones. This is the world. The more powerful people are, the lower the profile. The rest is to blow big, blow it up!"
"970 is just better than snapdragon 845 in artificial intelligence, and its actual running score is a little lower than 835"
"often, the profit created by a high-end flagship model is equal to four or five or even dozens of low-end models?"—— It can be seen that the cost of high-end machine is not high, where to go! "
"Qualcomm: it's time for us to make 855"
"A10 and 845 will be enough for you. Would I be beaten if I said that? "
"has the running score software been optimized for A12? A11 is much higher than 970 in running points. Why is my 8plus not as smooth as mate10pro? Did you take the money
"a series CPU is absolutely the king of the same period, which can't be denied, but GPU is not as strong as Qualcomm, which can't be denied"
"wait for Huawei mate5g to support domestic procts in 2019"
There are obvious differences between a11 and A12 in CPU, GPU and AI performance. Taking antinu as an example, the total score of the former is 28833, while the running score of the latter is 315047. A12 has greatly improved in GPU performance and UX performance; In geekbench, the score of the former is 10251 points, the latter is 11441 points, the former is 4229 points, the latter is 4833 points. The following is a detailed introction:
1. In the running score of antinu, A12's running score is 315047, while a11's total score is 28833, which has a significant improvement in GPU performance and UX performance; In geekbench, A12 scored 11441, while a11 scored 10251; The single core scores were 4833 and 4229 respectively; In addition, compared with a11, A12 also has several times improvement in AI computing performance, with better intelligent HDR, face ID recognition speed and AR performance
The new A12 bionic processor, like a11, adopts six core design, including two high-performance cores and four low-energy cores. In terms of hardware architecture, the biggest is the improvement of CPU architecture. A12 adopts Apple's self-developed fusion architecture, both of which are 2 (performance core, 15% performance improvement) + 4 (energy efficiency core, 50% power consumption improvement). GPU image core is upgraded from three core to four core, with 50% official performance improvement; A11 is also TSMC's 10nm process. Compared with A10, the performance of large core is increased by 25%, that of four small cores is increased by 70%, and that of multi-performance processing is increased by 75% In addition to GPU and CPU, as a bionic processor, the AI performance of A12 has also been improved. A12 adopts Apple's newly designed neural network engine and 8-core design. It can perform 5 trillion operations per second (a11 is 60 million). In addition, Apple will also open the neural network engine to core ml, which will enable the machine learning ability of A12 chip to be increased by 9 times compared with before, while the energy consumption will be reced to one tenth of the original. Thanks to the stronger A12, the face ID recognition speed of iPhone XS series is faster and the recognition rate is higherAI, a7 and AIO form an isosceles right triangle, so the angle aia7aio is equal to 45 °< br />，
From the experience of many people, the mobile phone experience of Huawei's Kirin 980 is actually closer to that of Apple's iPhone. They have achieved the ultimate level of hardware and software compatibility
More importantly, in terms of system matching, Huawei Qilin 980 is obviously better than most Xiaolong 855 models. Huawei can achieve 60% software speed improvement only by ark compiler, which is not possessed by many domestic mobile phone manufacturers. It can be seen that Huawei Qilin 980 is not as good as Xiaolong 855, but it feels smoother to use, which further reflects the strength gap between mobile phone brandsSnapdragon 865 is relatively strong. In mobile phones based on Android 10.0 system, the single core runs more than 4100, and the multi-core runs more than 12900. Compared with A12 chip, the single core runs are basically the same, but snapdragon 865 multi-core runs far ahead, and the performance of 865 chip exceeds A12 has become a fact. In this way, snapdragon chip is no longer suppressed by Apple chip
the CPU of snapdragon 865 can reach 3.2ghz, this time it can really be said that the CPU performance is excessive. Although the single core and multi-core performance of snapdragon 865 officially exceeds that of A12 processor, in Apple's opinion, this chip is outdated and A13 chip will be released soon. Therefore, the biggest rival of snapdragon 865 is A13 chip
extended data
through snapdragon x55 modem and RF system, snapdragon 865 supports all modes of 2G / 3G / 4G / 5G, sub-6ghz / millimeter wave, TDD / FDD, NSA / SA, DSS (dynamic spectrum sharing), carrier aggregation, and the download speed can reach up to 3.7gbps
at the same time, they will continue to improve in photography, artificial intelligence and games, including supporting 4K HDR video shooting and integrating the fifth generation AI engine. Snapdragon 865 platform has twice the AI computing performance before, and even supports the image computing capacity of up to 200 million pixels per second. It can support 8K 30fps video recording
