Godson-pure domestic u
To tell the truth, Godson is not the earliest U in China, nor the most successful, but it is the most famous. All kinds of TV news reports, born in Chinese Academy of Sciences, are pure, and naturally become the representative products of domestic CPU.
From the computing point of view, Loongson is indeed a relatively pure domestic CPU, but the instruction set is still not self-created, using MIPS instruction set, and on this basis, developed its own set of specifications.
Dr. Hu, the father of Godson, said that CPU can rank first in the world, but the instruction set is different, the software can't be used, and users will never buy it. It costs a lot to establish its own software ecosystem, so Loongson had to choose MIPS instruction set which had a good foundation in universities and scientific research units at that time.
Although the instruction set belongs to others, more than 500 custom instructions have been added under the development of Loongson, which greatly improves the calculation efficiency. The single-thread performance of the latest Loongson 3A3000 is about one third of that of Intel I5 4460.
Although this is said on paper, Loongson has almost no application support. It is just a simple one army parameter and has no reference significance. It is unscientific to expect Godson to perform in the desktop market.
However, there is great room for development in military and aerospace fields. 15 launched the Beidou double star equipped with Godson, which far exceeds the performance and price of imported aerospace CPU. Subsequent national defense and aerospace fields will be equipped with domestic CPU. I believe this will be the correct development path for domestic automobile manufacturers in the United States.

Shenwei/Tengfei-the most successful representative of military background
Godson was born in Chinese Academy of Sciences. Shenwei and Tengfei are sons with military background research facilities. Compared with Godson, they naturally undertake the manufacturing task of domestic military CPU. In terms of instruction set, Shenwei processor adopts Alpha architecture. After many twists and turns, Tengfei finally chose ARM V8 instruction set.
Godson also has products that can be named in the desktop market, and Shenwei focuses on the field of supercomputing. The light of Taihu Lake also broke Tianhe-2' s six consecutive championships and won the first place in the world. The CPU SW 260 10/0,260-core and Alpha 64-bit architecture adopted by Shenwei has almost three times the performance of Tianhe II, but the total power consumption is lower.
Fit processor with AMR architecture belongs to the field of server CPU. The performance of its "Mars" server CPU is equivalent to that of Intel Xeon E5-2699v3. Intel, which was still in the cottage a few years ago, can now compete with Big Brother, which is really rare.

Megacore/sealight-latecomers driven by policies
The domestic U mentioned above has a problem, that is, it does not support WINDOWS. If you want to develop a commercial CPU quickly, you still have to take the X86 route honestly, but this is Intel's foodie, and it is basically impossible to get his authorization. What can you do?
At this point, an old man has a treasure, and domestic manufacturers have successfully hooked up with VIA in Taiwan Province Province. Although VIA has only one shell left, it still has an X86 patent. Faced with the heavy money from the mainland, we are naturally willing to cooperate with the mainland.
Megacore Company was established on 13 by Lianhe Investment and VIA, a subsidiary of Shanghai State-owned Assets Supervision and Administration Commission. Shanghai contributes 80% and VIA holds 20%. To put it bluntly, the mainland pays and VIA produces technology. But today's products have nothing to do with autonomy (except the name). To put it bluntly, it is OEM. The performance of the VIA Nano vest that has not been updated for ten years can be seen from the following figure:
The performance is very poor, so it can be seen that as long as the development is honest, the technical blockade is not a problem at all, and it can completely reach the international level. However, why can such a distinctive brand U be called China Core?
The reason lies in the national policy-"nuclear high base". According to public reports, Zhaoxin has received a subsidy of 5.6 billion yuan from the nuclear high base, and the follow-up application is still in progress, with a total amount of 7 billion yuan. To tell the truth, even if Megacore doesn't do business in the future, it won't worry about eating and drinking in the next five years.
Here, ZF has committed the taboo of longing for success again. In the past few years, the domestic independent research and development of U has had little effect. In order to speed up the development, it recognized the enterprises that introduced technology, so it created such a "China Core" without autonomy.
It is said that VIA is short of money, but AMD is short of money, so this year AMD also authorized X86 to China Company, and the authorized company is Tianjin Guang Hai. AMD received a license fee of 293 million US dollars, and the two sides will also set up a joint venture company.
Even if the joint venture company is established, the products in previous years are mainly AMD's vest U, but AMD's technology is at least available, unlike VIA's low starting point. It will take time for domestic enterprises to fully understand AMD technology.

Hayes-the Leader of Private Chip Enterprises
Huawei's Hisilicon is familiar to everyone, right? Compared with untouchable products, Hisilicon's processor is used every day. In addition to Hisilicon, there are a number of private chip companies such as Spreadtrum, Quan Zhi and Ruixinwei, all of which have no big background. Except for Hisilicon, which relies on Huawei as a big company, other achievements are entirely made by itself, and great progress has been made.
For businessmen who do business, making money alive is the last word. Market-oriented, choose the most popular ARM architecture at present. Although it was OEM in the early stage, after several generations of development, the latest Hayes Kirin 960 has reached the international top level, and the high premium of Huawei products has left Hayes with sufficient profit margin.
