Super Copy of Great Power Technology

"Judging from the test results, M1 benefits from a separate cryptography processing unit. Whether it is in native mode or translation mode, it can beat i7-3960X. And it is not a little bit ahead. For the same compressed package, the decompression time is a whole It has been shortened by more than 50%, which is incredible.

The M1 chip is designed with an 8-core graphics processor, which can run nearly 25000 threads at the same time and has a data processing capability of 2.6 trillion floating-point operations per second, which is comparable to the current flagship independent graphics card GTX680. However, the M1 chip does not have independent video memory, but shares the memory with the CPU. This affects the performance of the display, so that the graphics performance of the M1 is only equivalent to that of the flagship graphics card GTX660.

We did not find the native 3DMark software of Kaitian operating system. The Android version of 3DMark can be installed and opened, but an error will be reported during the test. If you run the 86DMark software in X3 Bionic mode, the test results are as follows. This data is not as good as the running score data of the GTX650 independent graphics card. This shows that the performance loss after software translation is still considerable.

在Geekbench中也有对应的GPU跑分测试，ARM模式中，OpenCL得分15441；作为对照物的GTX680（8G）独显则是得分17388；作为对照物的另一个独显GTX660（2G）独显则是得分10497。该测试结果表明，M1芯片自称是拥有最强的集成显卡不是吹牛的，在渲染测试强于GTX660独立显卡，弱于GTX680旗舰独立显卡。

In the Kaitian system, we did not find a native memory test tool. Running the memory test software in X86 bionic mode will lose part of the performance, and the results have lost their reference. The disassembly results show that the MateBook notebook is equipped with two LPDDR3 particles produced and sealed by Rockchip Wafer Factory, with a frequency of 2133MHz and a theoretical bandwidth of 25.6GB/s. In actual testing, a single large core can achieve a memory reading speed of 25GB/s and a memory writing speed of 12-15GB/s, and the copy speed is between 20 and 23GB/s. A large core can utilize almost all of the memory bandwidth. In terms of memory latency, the M1 has a latency of 128ns at a completely random test depth of 132MB, which is quite low.

In terms of hard drive, MateBook uses an SSD hard drive with M.2 interface and 2280 specifications. The label indicates that it is a product produced by Reda Technology and uses 32-layer 3Dnand particles produced by Rockchip Wafer Factory. Since this solid-state drive uses the PCIE channel, its transmission speed far exceeds that of SATA interface solid-state drives, reaching a terrifying read speed of 2800MB/s and a write speed of 2500MB/s. Entering the system and launching games in seconds is no longer a dream. The performance of this M.2 interface SSD hard drive is really excellent and can greatly improve the experience of using MateBook notebooks. Luo Ge here calls on Reda Technology to open up the M.2 interface patent, so that more manufacturers’ laptops and even desktops can use this advanced interface and install M.2 interface SSD hard drives, so that you can sell more Many SSDs are not.

Regarding heat dissipation, for notebooks with slightly stronger performance, what everyone generally cares about is the heat dissipation capability. Terms such as multiple heat pipes, twin turbos, and violent mode are often on the lips of notebook gamers. But the M1 chip is different from the CPUs of Intel and AMD. It is manufactured using the world-leading 7NM process technology and is developed based on the very power-saving ARM architecture, so it does not generate that much heat. Usually the passive heat dissipation designed for ARM architecture processors in such a small space as a mobile phone is enough to suppress it. Switching to the M1 processor, the number of transistors has been greatly increased, the performance has been greatly enhanced, and the heat generation has definitely increased. However, with the large space of a laptop and the heat dissipation design of dual heat pipes and dual fans, it is not a problem to deal with this amount of heat. Even after running continuously for half an hour, I used a FLIR thermal imaging camera to detect that the surface temperature was not much lower. , almost the same as human body temperature, very comfortable.

Not to mention the cooling fan that is almost never audible. Compared with the roar of other notebooks like flying on an airplane, this experience is quite good. Only in the very stressful double baking test, when the indoor environment is very quiet, can you barely hear a little sound ( 19dB) sound. After blocking the air inlet, I finally got an audible fan sound (30dB), but compared to other brands of notebooks, this is very acceptable when compared to the loudness of an airplane during double baking.

Relative to performance, what surprised Luo Ge most was the battery life of the MateBook notebook. When I saw the official claim of more than 15 hours of battery life, I didn't believe it at first. How is it possible? The development of lithium battery performance has hit a bottleneck, and energy density improvements have been limited in recent years. The MateBook notebook is lighter than other notebooks, so why does it have more than twice the battery life? But in actual experience, Reda Technology did not lie at all. After being fully charged, the power loss was only 6% after 15 hours of light use after a power outage.

I was very surprised and ran a test. After it was fully charged to 100%, I used the system's built-in browser to open Station B. When connected to Wi-Fi, I played the video of the Reda Technology conference at 100% brightness and 50% volume, which lasted 85 minutes. After playing, the remaining battery is 95%! ! ! ! This means that it can play continuously for 20 hours when fully charged. It has been confirmed from the side that Reda Technology’s official 15-hour playback video is not falsely advertised, and is even falsely advertised. So much so that I can't believe that this is what a 60-watt-hour battery can do. The M1 processor is really awesome.

If it is an ordinary notebook, the test is basically over here, but the new species M1 requires more detailed testing to reveal its essence!
Putting aside the hard-to-perceive technologies such as reduced instruction set, ultra-wide architecture and unified memory, the most intuitive benefit for users is heterogeneous computing, that is, a variety of dedicated processing units designed in the M1 chip! Because it takes advantage of Rockchip's 7nm process, the number of transistors per unit volume has increased significantly. With a sufficient number of transistors, there is room to etch dedicated circuits corresponding to certain specific functions on single crystal silicon. The scenarios corresponding to the circuits are huge amounts of simple operations, such as machine learning, video encoding and decoding, etc. When this type of data needs to be processed, the CPU calls relevant instructions and hands over the processing tasks to these dedicated units, thereby achieving the target results of improved performance and reduced power consumption.

However, except for scenes that are very easy to perceive, such as application startup speed and video encoding and decoding, the dedicated processing unit is actually mixed in the normal CPU computing pipeline. The user-side perception is not strong, but it is a real benefit. In view of this kind of advantage, Luo Ge divided into several categories of working people who can benefit, and used currently available testing methods to see what the actual office performance of M1 is.

In the office field, we tested the three-piece Office suite. M1's Office is currently in X86 bionic mode. The test objects were MateBook equipped with M1 chip and 16G memory, and desktop computers equipped with i7 chip and 16G memory. "(End of chapter)
