On April 1, 1976, two young Steve Jobs and Steve Wozniak founded apple in a garage. After years of development, MAC team is growing larger and bigger. Jobs wants to keep the original rebellious spirit even though they are more and more like regular Navy. In August 1983, the MAC team moved to a larger office. The MAC team wanted to leave their mark because there was no feature in that place. Steve CAPPS, who came from Lisa, has an inspiration: if the MAC team is a group of pirates, then a pirate flag should be hung on the building, symbolizing Apple’s think difference. In June, Apple announced that it would decide to transfer its MAC back to its own chip. And at the launch, the first new arm architecture Mac will be unveiled at the end of the year. At the beginning of the conference, M1 chip was directly displayed. The 5-nanometer process, with 16 billion transistors, is the strongest self-developed chip in apple at present. The

< p > 8 core CPU includes four high performance cores and four high efficiency cores. Each high-performance core provides excellent single thread task processing performance and minimizes energy consumption to the extent permitted. Even four energy efficient cores offer performance similar to the existing dual core MacBook Air, but only one tenth of the previous power consumption. Graphics processing GPU has 8 cores, which can run nearly 25000 threads simultaneously, and has the data processing capacity of 2.6 trillion floating-point operations per second. With this performance added, it can play multiple 4K video streams smoothly, and can render complex 3D scenes. Compared with other models with high-performance integrated graphics card, the performance has been improved by 6 times. With the addition of 16 core neural network engine, the machine learning speed is increased 15 times. In addition, there are the latest ISP (image signal processor), the latest hardware security partition, storage controller, low-energy media coding and decoding engine, and support for USB 4. More importantly, after Apple uses its own customized chip, because of its more flexible power consumption, the inherent advantages of control and arm architecture have doubled the MAC endurance capability of M1 chip. You can see, it’s not hard to understand why Apple must be a Mac chip, not follow Intel’s chip update pace. As I mentioned in previous articles, in the six years from 2013 to 2019, the performance of single core has only increased by 25.4% and multi-core performance increased by 122%, but it is not until 2018 that the multi-core performance can be greatly improved after Intel updated the coffee Lake chip. In this time, Apple’s own A-Series products used by iPhone have increased their performance by 5 times, and the performance of multi-core has increased by 6 times. When M1 chip officially appeared, the MAC new product with M1 chip finally ushered in a performance improvement that can be measured by “n times” and doubled the endurance capacity. It is also because Apple realizes its own computer from chip to hardware to system, and MAC has more unique and advantages than other computers. For example, before changing arm architecture self research chip, Mac will realize touch bar, fingerprint unlocking, voice hand of “Hey, Siri” and multimedia accelerator by hanging an arm architecture chip called Apple T2 into the machine. After the chip is completely changed to arm architecture, MAC with M1 chip can wake up immediately from sleep mode like iPhone and iPad, greatly improve performance and better heating control. App on IOS and ipados platform can also be used on Mac. Apple wants to convert all its devices to arm processor in the next few years. The first step is to update the low entry-level products. So last night, the new MacBook Air, 13 inch macbook pro and mac mini were officially released. The first is MacBook Air, which is designed without fan, and is quieter. Compared with the previous generation, CPU performance is 3.5 times higher, GPU performance is increased by 5 times, machine learning ability is improved by 9 times, and the performance of solid-state hard disk is twice. For the first time, it can play and clip multiple 4K pros video streams of full quality in Final Cut Pro without worrying about losing frames. With better performance deployment, the life span has also increased from 11 hours wireless Internet / 12 hour video playback to 15 hours wireless Internet / 18 hour video playback. But it is important to note that MacBook Air can only call 7 core GPU (8-core GPU needs to be added for selection) in order to limit heating or to pull apart product positioning difference. The new 13 inch MacBook Pro can almost run full of M1 chips. According to Apple’s official statement, the new 13 inch MacBook Pro, combined with single fan, actively heats up, improves CPU by 2.8 times, GPU increases by 5 times, and machine learning increases by 11 times. Thanks to the excellent performance of neural network engine, the beat, instrument and voice in the recording can be separated in real time in djay Pro AI. The read speed of solid state hard disk is 3.3gb/s, and the endurance capacity has also been improved to 20 hours video playback. It is the MAC product with the strongest endurance capacity at present. As with the previous two notebooks, mac mini has the same performance improvement, 3 times CPU, 6 times GPU and 15 times machine learning. After all, the last generation Mac Mini has been an 18 year old product. It seems that the location of Mac Mini has changed a little. The Mac Mini can be selected to the maximum 64g memory and 10 megabyte network port to meet the needs of some extreme professional use. But after replacing M1 chip, the maximum memory of Mac Mini can only be selected to 16g. As can be seen from the official website information, M1 chip may be the first step of self research chip positioning of Apple arm architecture in the entry-level market. At the highest, it can only be selected to 16g memory, MacBook Air and other absolute entry-level products, as well as small devices like mac mini, are replaced with M1 chips. However, for the 13 inch MacBook Pro, it still hangs “pro” ”The name of the product, Intel processor version is not offline, still official website is on sale. It is important to note that although M1 chip is replaced, the mold of these three devices has not changed, that is, there will be no difference in appearance from the old one before. From announcing that MAC is gradually turned to arm architecture self research chip, to release three new Mac equipped with M1 chip at once, the performance of “multiple” is released to the outside. Every new product has no difference in drawing a mouth in the whole industry, or more directly, it has hit Intel face of “toothpaste factory”. Everyone wants to be the leader of the industry and want to lead the era and change the computer for ARM architecture. Microsoft has tried to do it twice. The windows RT has done it, and failed to give up. The portable and thin computers of Xiaolong processor are not sold well. But note that Microsoft failed because there is no mobile ecology on PC system, no developer develops app for arm windows, while iPhone and iPad based on arm have developed into an app store ecology that can affect more than $500billion a year. As desktop end system, MAC is compatible with mobile devices like iPhone and iPad App, it’s very easy in theory. But the software that only runs on x86 architecture needs the support of developers to change. So Apple also predicts that the whole transformation process will take two years. What can be done now is to provide developers with enough support to facilitate the development of the MAC under arm architecture. In 2006, apple prepared Rosetta for developers to facilitate the transition from power PC chips to Intel new products. 15 years later, Rosetta 2, as a built-in simulator in MacOS Big Sur, allows developers to directly adapt the original x86 software to arm architecture MAC without changing the architecture. This transformation process is not easy for Microsoft, but it has to be admitted that it is not as hard as it is to encourage developers to support Apple’s transformation because of the better sharing of benefits. Because of this story, we have seen it once in the past decade when the iPhone was rising, even more time forward. We have seen the first MAC as the first PC with a graphical interface. What Apple wants is not only to take the initiative of its own computer product line from Intel, but to control the development trend of the whole computer industry, even the future development trend of computing equipment in the whole world. The problem is that if you try the first wave of MAC with M1 chip from the user’s point of view, although there are so many performance and endurance improvement on the surface, it is still necessary to verify whether the actual software compatibility experience is true or not. After all, for most people, computers are essential to work and most need a stable software experience. This paper is about how to use M1 to make MAC chips have such strong performance, good compatibility and actual experience. We will see in a few days. Global Tech
