Changing the core of apple computer means more than doubling its life span

While everyone was busy shopping on the double 11, apple held a press conference once again. This is the third online launch after the launch of Apple watch series 6 and Se in September and the iPhone 12, iPhone 12 Pro Series and homepod Mini in October. < / P > < p > the new chip named M1 is the protagonist of this conference. In fact, it is a chip named “M1”. The chip, which was made by Apple itself and designed for MAC computers, will gradually replace the Intel chip currently used on Macs. The M1 chip based on ARM SoC architecture has the characteristics of low power consumption and high performance. Compared with Intel chip, the biggest difference of Apple’s M1 chip is that it is an ARM SoC chip with low power consumption, that is, it integrates CPU, GPU, input and output into one chip, which is usually used in chip design of mobile phones and tablet computers. However, the CPU of Intel, such as i5 / i7, which we are familiar with, is often high-power and independent. It needs to be combined with GPU to form a complete system. Its performance upper limit is high. However, due to the relationship between its volume and energy consumption, only notebook computers and desktop computers can be used. M1 chip is applied to the new generation of MacBook Air and MacBook Pro. The biggest direct improvement for consumers is of course the endurance. When the battery is fully charged, the battery life of the notebook directly doubles, from about 9-10 hours to about 17-20 hours. It can be used for a full day without plug-in. But is it just that? < / P > < p > the MacBook Air equipped with M1 chip can greatly improve its endurance. After solving the performance bottleneck, it may redefine the computer and apply ARM SoC chip to the computer, which is not the first idea of apple. However, the performance of SOC chip is probably the most prominent one among many practical problems to be faced with when replacing the “core”. Compared with the applications that mobile phones and tablets need to run, things people do on computers often require higher computer performance. For example, editing high-resolution pictures and videos requires high-frequency CPU and strong independent graphics card. Can traditional SOC chips do the same thing? Apple claims that this M1 chip has powerful performance, equipped with an 8-core CPU including four high-performance cores and four energy-efficient cores, and can run nearly 25000 threads at the same time. From playing multiple 4K video streams smoothly to rendering complex 3D scenes, the M1 chip can be easily handled no matter how demanding the task is. In addition, M1 chip has 2.6 trillion floating-point operations per second data processing capacity, surpassing all the current PC integrated graphics cards. At the press conference of the mainstream PC industry, the M1 processor was compared with that of the mainstream PC. Under 10W power consumption, the CPU performance of M1 is twice that of competitive PC processor, and M1 can match the peak performance of competitive PC processor with only a quarter of power consumption. Compared with the chips of traditional notebook computers, M1 has obvious performance advantages at the same power consumption level. At the same time, M1 chip, like A14 chips used in the new generation iPhone and iPad, is equipped with apple neural network engine, which can increase the processing speed of machine learning tasks to 15 times of the original. < p > < p > the MacBook Pro with M1 chip runs complex programs without pressure. It can be said that according to a series of data and performance released in the press conference, Apple may really break through the performance bottleneck of ARM SoC chip. This means that the product of “personal computer” may be redefined, and it will be more seamless with smart devices such as mobile phones. For example, on MacBook Air and MacBook Pro equipped with M1 chips, not only can you run applications developed for Mac, but also massive apps developed for iPhones and iPads can run directly on these laptops. For many people, this makes a lot of sense: for example, you can continue to play on your computer, and all your account information and information are seamlessly transferred. This laptop can never be turned off < / P > < p > the press conference specially used a camera to show the new features of MacBook equipped with M1 chip: Vice President Craig federighi opened the MacBook, and the screen lit up instantly. This is another major feature of M1 chip: fast response. The traditional laptop experience is that when you don’t use it for a short time, you can cover it, and the computer goes into sleep to save power and respond quickly, but in fact, this speed is not so fast. If you don’t use it for a long time or you need to run around with your computer on your back, you’d better turn off the power completely, because the dormant notebook actually consumes power, and sometimes the computer will crash due to vibration and other unknown reasons. < p > < p > and apple has always wanted users to “never turn off” their macbooks like they do with iPhones or iPads – turn them on when they want to use them and close them when they don’t use them. This is the most convenient and fast response time. With the M1 chip, this experience has evolved to the extreme. Its wake-up speed and standby energy consumption are the same as those of mobile phones, and the system will not have any problems due to long-term standby. < p > < p > the Mac Mini is a super small desktop computer. It is worth noting that the three MAC models equipped with M1 chip are MacBook Air, macbook pro 13 inch version and mac mini. On some higher end models, Intel processors are still used. Obviously, apple is very cautious about changing the core as a whole. Apple said the three models are the beginning of the transition of all Apple computers to a new family of chips designed specifically for Macs, which will be completed in about two years. In the long run, with the continuous development of technology, it is believed that the trend brought by M1 chip will also become an important direction in the development of personal computers.
