Two young Steves, namely Steve Jobs and Steve Wozniak, formed Apple in a garage on April 1 , 1976.
Wednesday, November 11, 2020, 1:01 GMT
The Mac team grew larger and larger a few years after the development of the venture. What Jobs required was that the squad also had to keep the initial defiant attitude, while they looked more and more like a normal navy. The Mac team relocated to a new office location in August 1983. The Mac team decided to leave its mark because there is nothing special about that venue. Steve Capps of the Lisa team has an inspiration: to symbolize Apple’s Thought Different, if the Mac team is a gang of pirates, then a pirate flag should be hung on the building.
Of instance, the spirit of revolt appears to be scarcely discussed until Apple got on the right track and became a giant.
Apple’s defiant nature and sense of humour had recovered before last night, Apple’s last online conference this year.
Apple revealed its decision at WWDC in June to turn its Mac back to its Apple chip. And at the press conference, it was revealed that the first new Mac ARM architecture would be introduced at the end of the year.
One sentence is also the preview of a press conference: One More Thing.
As a result, at the Press Conference, Apple announced 3 More Items in less than 45 minutes.
The new MacBook Air, the new 13-inch MacBook Pro and the new Mac Mini will be formally unveiled next week and will be revealed today.
The value of chips that are self-developed
The M1 chip was specifically announced at the end of the session. It is currently Apple’s most efficient self-developed chip, with a 5-nanometer process and 16 billion transistors.
The M1 chip is fitted with Apple ‘s fastest CPU and integrated graphics, according to Apple’s official release.
Four high-performance cores and four energy-efficient cores are part of the 8-core CPU. Every high-performance core offers outstanding performance for single-threaded task processing and minimizes energy consumption within the permitted range. And even the 4 energy-efficient cores, comparable to the current dual-core MacBook Air, can provide performance, but power consumption is only 1/10 of the previous one.
The GPU for graphics processing also has 8 cores, can run almost 25,000 threads concurrently, and has 2.6 trillion floating-point operations per second data processing capabilities. Multiple 4 K video streams can be played seamlessly with this blessing of performance, and intricate 3D scenes can be made. The performance is increased by a complete 6 times, relative to other versions that use high-performance integrated graphics.
The machine learning speed is increased by 15 times coupled with the 16-core neural network engine. In addition, the new ISP (Image Signal Processor), the latest security compartment for electronics, the storage controller, the low-consumption and high-energy media encoding and decoding engine and USB 4 support are available.
More importantly, after Apple used its own custom chip, because of the more flexible control of power consumption and the inherent advantages of the ARM architecture, the battery life of the Mac with the M1 chip has been doubled.
You see, it is not difficult to understand why Apple must make its own Mac chips instead of following Intel’s chip update rhythm.
As I mentioned in the previous article, in the 6 years from 2013 to 2019, the single-core performance of the MacBook Pro with Intel chips increased by only 25.4%, and the multi-core performance increased by 122%, but this is not until After Intel updated the Coffee Lake chip in 2018, the multi-core performance began to increase significantly.
In the same period of time, the single-core performance of Apple’s own new A-series products used by the iPhone has increased a full 5 times, which is close to the Intel chip, and the multi-core performance has increased by 6 times.
When the M1 chip was officially unveiled, the new Mac equipped with the M1 chip finally ushered in a performance improvement that can be measured by “N times” and a doubled battery life.
It is precisely because Apple has realized the independent control of its own computer from chip to hardware to system, the uniqueness and advantages of Mac compared to other computers will be more obvious.
For example, before changing to the ARM-based self-developed chip, the Mac will plug an ARM-based chip called Apple T2 into the machine to realize Touch Bar, fingerprint unlocking, “Hey, Siri” voice hand, multimedia accelerator, these Features.
After the chip is completely replaced with the ARM architecture, the Mac equipped with the M1 chip can wake up from sleep mode like iPhone and iPad. The performance is greatly improved, and the heat control is better. Apps on iOS and iPadOS platforms can also be used on Macs .
Crazy increase of three new products
Apple wants to convert all its devices to ARM-based processors in the next few years. The first step to update is entry-level products with low positioning. So last night, the new MacBook Air, 13-inch MacBook Pro and Mac mini were officially released.
Although they all use M1 chips, in order to make a distinction between performance levels, Apple has obviously moved some thoughts.
The first is the MacBook Air, which uses a fanless design and is quieter. Compared with the previous generation, CPU performance has increased by 3.5 times, GPU performance has increased by 5 times, machine learning capabilities have increased by 9 times, and the performance of solid-state drives has also increased by 2 times.
Apple officials also gave some improvements in actual scenarios:Export projects to web pages through iMovie editing, up to 3 times faster. Integrate 3D special effects into video in Final Cut Pro, speed up to 5 times. For the first time, multiple full-quality 4K ProRes video streams can be played and edited in Final Cut Pro without worrying about frame loss. Export photos from Lightroom, up to 2 times faster.
These “N times” comparisons are compared to the previous generation 1.2GHz 4-core Intel Core i7 processor MacBook Air.
This is definitely the biggest performance leap since the birth of the MacBook Air series.
Because of the better performance allocation, the battery life has also been upgraded from the original 11 hours of wireless Internet access/12 hours of video playback to 15 hours of wireless Internet access/18 hours of video playback.
The starting price remains unchanged at 7999, and the maximum 16G memory version can be selected.
However, it should be noted that it may be to limit heat generation or to open up product positioning differences. MacBook Air can only call 7-core GPU (8-core GPU requires additional money for optional). And the new 13-inch MacBook Pro can almost run the capacity of the M1 chip.
According to Apple’s official statement: the brand new 13-inch MacBook Pro, with a single fan for active cooling, CPU is increased by 2.8 times, GPU by 5 times, and machine learning by 11 times.
And in the actual usage scenario of 13-inch MacBook Pro:Write code in Xcode, speed up to 2.8 times. Render 3D subtitles in Final Cut Pro, up to 5.9 times faster. Smoothly design complex game scenes in the Unity Editor, with speeds up to 3.5 times faster. Perform machine learning tasks in Create ML, up to 11 times faster. Thanks to the excellent performance of the neural network engine, the beats, instruments and vocals in the recording can be separated in real time in djay Pro AI. Play full-quality 8K ProRes videos in DaVinci Resolve without worrying about frame loss. Thanks to the breakthrough performance-to-power ratio of the M1 chip, it can compile up to 4 times the code with a full charge.
These scenes compare the previous 13-inch MacBook Pro with a 1.7GHz 4-core Intel Core i7 processor and Intel Iris Plus Graphics 645 graphics processor.
The reading speed of the solid-state drive is up to 3.3GB/s, and the battery life has also been increased to 20 hours of video playback. It is currently the strongest Mac product with the strongest battery life.
Like the previous two notebooks, the Mac mini has a huge performance boost, 3 times the CPU, 6 times the GPU, and 15 times the machine learning. After all, the previous generation of Mac mini has been a product for 18 years.
It just seems that the positioning of the Mac mini has undergone some changes. The previous Mac mini can be equipped with up to 64G of memory and 10 Gigabit Ethernet to meet some extreme professional use needs. But after replacing the M1 chip, the maximum memory of Mac mini can only be selected to 16G.
It can also be seen from the information on the official website that the M1 chip may only be the first step for Apple’s ARM-based self-developed chip to be positioned in the entry market. The highest can only be equipped with 16G memory, absolute entry products such as MacBook Air, and Mac mini. Such niche devices have been replaced with M1 chips across the board, but for products like the 13-inch MacBook Pro that still bear the “Pro” name, the Intel processor version has not been removed from the shelves, and is still on sale on the official website.
However, it should be noted that although the M1 chip has been changed, the molds of these three devices have not changed, that is to say, there will be no difference in appearance from the previous old models.
Apple’s rebellion and hidden worries
From the announcement of the Mac’s gradual shift to the ARM-based self-developed chip, to the release of three new Macs equipped with the M1 chip, the performance of “multiples” has been released. Each new product is tantamount to taking the entire industry A mouth, or to put it more directly, hit the face of Intel, a “toothpaste factory”.
It is no exaggeration that this is the most rebellious thing in the entire consumer digital circle in recent years.
Everyone wants to be the overlord of the industry, wants to lead the era, Microsoft has tried twice to replace computers with ARM architecture, and it has done it on Windows RT, but failed and gave up. The portable and thin computers with Snapdragon processors are not selling well. .
But note that the reason for Microsoft’s failure is that there is no mobile ecosystem on the PC system, and no developers develop apps for ARM’s windows, while the ARM-based iPhone and iPad have developed an App Store ecosystem that can affect more than 500 billion US dollars a year. , Mac as a desktop system, it is theoretically very easy to be compatible with mobile device apps like iPhone and iPad.
But computer software that originally only runs on the X86 architecture needs the support of developers to transform. Therefore, Apple also predicts that the entire transformation process will take two years. What it can do now is to provide developers with sufficient support to facilitate developers to develop under the ARM architecture Mac.
In 2006, Apple prepared Rosetta for developers to facilitate the transition from Power PC chips to Intel’s new products. Fifteen years later, Rosetta 2 is a built-in emulator in macOS Big Sur, allowing developers to directly adapt the original X86 software to the ARM-based Mac without changing the architecture.
This set of transformation process is not easy to put Microsoft there, but I have to admit that because there is a relatively good profit sharing, encouraging developers to support Apple’s transformation is not as strenuous as expected. Because of this kind of story, we have seen it once in the past ten years of the rise of the iPhone, and even more time has passed since the first generation of Mac as the first personal computer with a graphical user interface. Have seen it once.
What Apple wants is not only to take back the initiative of its own computer product line from Intel, but to control the development trend of the entire computer industry, and even the future development trend of the entire world’s computing equipment.
But the problem is that, from the user’s point of view, if you try the first wave of Macs that use the M1 chip, although you have seen so many performance and battery life improvements on the surface, is the actual software compatibility experience true? Reliable, it still needs actual verification. After all, for most people, a computer is a must for work, and a stable software experience is most needed.
The article has written so much. Will the performance of this wave of Mac chips using M1 really be so strong, whether the compatibility is good, what is the actual experience, and see in a few days.
