Mid-December.

The "Home Computer" research center set up in Suhong City has good news of a breakthrough.

"Mr. Chen, the first batch of prototypes has been produced, and the use is very smooth, and the hardware and software systems have been successful!"

Hu Tengjiao, who was in charge of the project on the phone, said excitedly.

"The prototype is out?"

Chen Jin was slightly shocked, and the "Home Computer" project, which had been carried out for nearly two years, finally came up with substantial results.

……

The next day.

In order to show his attention, Chen Jin's ontology, with several executives, came to Suhong City and inspected the research center.

He sent his greetings to nearly 2,000 software and hardware R&D personnel in the research center.

Seeing the boss himself, the researchers were very excited, shaking hands with the boss and taking photos, and some female R&D staff even asked for a hug.

"It's hard work, everyone's hard work."

Chen Jin kept waving his hand, and the scene was very warm.

……

Product test room.

On a long table, Chen Jin saw two prototypes.

One of them is a home desktop computer, with a boxy main unit and a 19-inch monitor, which is no different from a regular home computer.

The other is a laptop, because it is a test prototype, the appearance is also square, and the thickness is comparable to that of the ThinkPad.

Hu Tengjiao, the general leader of the project, did not turn on the two computers immediately, but asked people to bring two chips.

Computer CPU chips!

THE PHYSICAL SIZE OF ONE OF THEM IS 4CM×4CM, WHICH IS HALF THE SIZE OF A PALM, AND FOUR TIMES THE SIZE OF A COMMON INTEL ...... This is a desktop computer CPU.

THE PHYSICAL SIZE OF THE OTHER IS 2.5CM × 2.5CM...... This is the CPU used by laptops.

"Both CPUs use Zhongxin's 28nm process technology, which is two to three generations behind Intel's most advanced 10nm process, but Intel's 10nm production capacity is seriously insufficient, and they are now mainly producing 14nm CPUs."

The surface area of a computer CPU is several times larger, and the number of transistors has also increased several times, even reaching tens of billions.

Under the same process, the larger the processing area, the lower the yield rate and the higher the cost.

Therefore, Intel's 10nm CPU, after three or four years of jumping, finally achieved mass production in 20X0.

The CPUs made by Zhongxin's 28nm process are of course worse, and can only be made up for the performance gap by increasing the area and the number of transistors.

Fortunately, after Chen Jin helped solve the problem of lithography lenses, the super-resolution lithography machine that Shangwei Electronics will soon launch can be used for the manufacture of 10nm computer CPUs, and can ensure that the yield rate is high enough...... It's almost immediately on par with Intel's state-of-the-art CPUs.

In addition, the CPU size here is several times larger.

In terms of performance, you don't have to worry about it at all.

What's more, this CPU, named 'Qinglong Generation', has a huge competitive advantage in terms of physical architecture, which is more common than X86 and MIPS architecture.

Liang Yongping, an engineer in charge of architecture, said:

"Mr. Chen, at present, the CPU architecture used by Intel and AMD is the X86 architecture, which occupies the absolute mainstream of the market."

"The X86 architecture adopts a complex instruction set, which has a mechanism for fast single instruction, a small number of instructions, and sequential execution of instructions, making its control relatively simple."

"However, the X86 instruction set only has 8 general-purpose registers, and CISC accesses most of the data in the memory during execution, while RISC (reduced instruction set) systems often have a very large number of registers, which slows down the whole system, and in some micro-decoding scenarios, the decoding speed will be slow and complex...... Therefore, the utilization rate of all parts of the computer is not high, and the execution speed is slow. ”

"The MIPS architecture with a reduced instruction set is similar to the ARM architecture, with a large number of core registers, which greatly reduces the power consumption by reducing the amount of data access to memory...... With the same performance, the MIPS architecture offers the highest lowest energy consumption per square millimeter chip design, and is more flexible and open to use. ”

"The disadvantage of the MIPS architecture is that there are certain limitations in memory and cache support, and there are some problems when dealing with high-capacity memory...... And there are advantages to this aspect of the x86 architecture. ”

Liang Yongping held the chip in his hand and put it in front of Chen Jin:

"But the 'Weaver Girl Architecture' used in our CPU takes into account all the advantages of the X86 architecture and the MIPS architecture at the same time, achieving fast speed, high performance, fast memory data exchange, and high CPU utilization, while the power consumption performance is comparable to the MIPS architecture."

"The shortcomings of other architectures are more or less shortcoming, but on our Weaver Girl architecture, all of them have been solved!"

"The fundamental reason is that the transistor distribution of this CPU is no longer the previous matrix arrangement, but uses a special 'array', which can evolve into many changes, so that those transistors sometimes become computing units, sometimes become memory units...... Intelligent transformation to meet a variety of usage scenarios. ”

"It's a perfect combination of high performance and low power consumption."

Chen Jin nodded.

The Weaver Girl Organization was brought over by him from the Dakeng base, and of course he was clear about the strength of this structure and the advantages it had.

In a word, this architecture is ahead of all the mainstream architectures on the market today.

It is an advanced product that exceeds a generation.

Not only does it achieve high performance and low power consumption, but it also has a killer feature.

And that is that it can be not only a pure CPU, but also a pure GPU.

That is, it can complete the full graphics rendering function of the graphics card, without having to buy the graphics card separately.

Generally speaking, the price of a slightly better CPU is about 1,000 yuan, but the performance of the built-in integrated graphics card is very poor, and you can only play some low-configuration games.

If you add a better graphics card dedicated to processing graphics operations and play a chicken game, the price will be at least 1,000 yuan or more.

Or even spend 2,000 yuan, 3,000 yuan, 5,000 yuan...... Half of the price of the entire host.

The combined price of the two things is about 60%~70% of a high-performance computer.

Now, based on the weaver girl architecture, the 'Qinglong generation' CPU, so that you don't need to buy a high-performance graphics card separately, the price is only 1500, will you be tempted?

Of course, considering that both CPU and GPU will greatly increase power consumption, if you run a game with extremely high configuration requirements, hundreds of watts of running power, and the huge heat generation may not even be able to suppress water cooling, you still have to develop an independent graphics card in the later stage.

But at the moment it is completely sufficient.

Because Hu Tengjiao shook the CPU that was half the size of a palm and said: "Mr. Chen, if this U can use the 10nm process, the performance after all participating in graphics processing is about RTX2080...... This is enough for the time being, and the vast majority of users don't have to think about adding a graphics card. ”

Chen Jin nodded, RTX2080 is already a super nuclear bomb, the market price is over 10,000, and the people who can afford this kind of nuclear bomb don't know that it is more than 1%?

Therefore, except for a very small number of local tyrant users, more than 99% of ordinary users, a CPU of 'Weaver Girl Architecture' is enough to get them for the time being.

Of course, no matter how good the hardware architecture is, it must be used with the operating system and software to exert the greatest power.

For example, although the X86 architecture has many shortcomings, due to the formation of the in-tel alliance with Microsoft, the result occupies the absolute mainstream of the market, and the indos system has played a decisive role in the wide application of the X86 architecture.

So Chen Jin's gaze returned to the two computers in front of him.

"Turn on your computer and let me see how the operating system performs."

"Yes."

Two staff members pressed the power button at the same time.
