Chapter 1453 Let's Start

This sentence is not contradictory, because you only need to taste carefully.

I strictly prohibit the export of lithography machines, but the company I sold to you has no problem. If you want to use it, you can. You can build a factory in our country. Besides, don’t you have a factory here? Just one more!

Although they did not have the most advanced chip factory before, they can have it now!

You build the factory here, and I don’t care if you export the chips you produce. You can sell them at will, but the lithography machine cannot!

Well, anyway, Jiang Yanhai didn't know about this plan. It was discussed by people from the Ministry of Commerce. This is a normal thing.

As for foreign ones, you can continue to ban our imports. Anyway, if you ban yours, I will ban mine.

Therefore, now that there is no shortage of lithography machines in China, tape-out is naturally not a big problem. For example, Sino-Singapore Technology, which Huawei often cooperates with, has already built several fabs with production lines in their hands, and their production schedule is currently full.

However, there is no problem with tape-outs from partners. These companies are also very clear that they did not lack orders at the beginning, but when the number of lithography machines increases in the future, it will still depend on others. order quantity.

Old customers must have discounts.

The speed at which Jiang Yanhai entered the working state was terrifying. Mr. Yu and Mr. Ren had to leave after staying in the laboratory for an hour. The main reason was that they stayed here and got in the way. Can't understand anything.

But from the expressions of these engineers in his company, it can be seen how strong Academician Jiang Ling is.

Only Ye Cunxin and the others remained in the lab, along with a silver fox, who was responsible for the security work here.

Everyone else has already left.

Jiang Yanhai didn't stay here for a long time. In just one day, in the evening, he completed the finalization of their latest generation chip, and found 22 design defects and optimized 17.

These design flaws are not fatal, but the overall correction has improved their chip performance by about 13.8%.

Don't underestimate this number. If you calculate it with tens of billions of transistors in the current chip, more than ten percent is equivalent to billions more transistors.

This is the importance of a good design!

For a day, these Huawei engineers were full of admiration when they saw Jiang Yanhai's expression. There was no way, it was too strong! The two parties are not at the same level as them at all.

In particular, they don't know what the other party's head is thinking. Sometimes there are some design flaws, and the other party can directly bring them up after only reading the design drawings, and when they are brought up, they are still justified. kind.

Although there is no way for them to simulate some aspects of performance through supercomputing, they have designed so many chips, especially the Kirin series for so many years, and they are more or less aware of these defects. Very remarkable.

However, even after Jiang Yanhai's design optimization, there is still a gap of about 8% in overall performance between their chip and the chip of Li Ruobai's research institute.

In addition, in terms of the number of transistors, they have more, but the number is not much, about 300 million more transistors.

In the case of an increase in the number of transistors, the overall overall performance will be 8% lower, and the design gap can be seen from this aspect.

But this is comprehensive performance. If you want to simply compare computing power, some extreme computing power is even surpassed by Warwick.

But what a chip looks at is really not the ultimate computing performance. Let's put it this way, although that thing is a main parameter...it's just not the most important.

"The basic design is like this. You can tape it out. About one day is enough. I will stay here for a day. After the tape-out results come out tomorrow, I can conduct a performance test." Always they stand together.

"Academician Jiang Ling, to be honest, it really opened our eyes. You alone are the top of a scientific research team of our company." Mr. Ren said with great emotion.

"They're not bad either, they're not bad." Jiang Yanhai was not modest, too modest would be unnecessary.

"However, Academician Jiang Ling, I have a heartfelt request." President Yu over there hesitated and said.

"Mr. Yu, please tell me." Jiang Yanhai said with a smile.

"It's like this... Our new product press conference is estimated to be held soon. After the chip has passed the relevant design, our press conference will definitely introduce the performance of the chip, so... we estimate that we will focus on Introduce the data on the number of transistors and the number of calculations...and please Academician Jiang Ling, can you keep silent."

Mr. Yu was a little embarrassed when he said this.

Jiang Yanhai laughed immediately. Of course he knew why. To put it bluntly, the reason for such a publicity was to make users who don't understand it feel superior.

Because ordinary people don't know what the advantages and disadvantages of a chip are. They can only judge by the number of transistors and the speed of operation. They think that the more transistors, the faster the operation speed, the better.

They don't know much about comprehensive performance evaluation data, because this is too professional.

But this can be regarded as an unspoken rule in the industry. Even if some rival companies sometimes mention these things, the weaker side does not expose them.

The reason is simple, tacit understanding, today your chip is higher than mine, if you make such a publicity, mine is higher than yours in another day, and I will do the same.

There may be people who tear down the stage, but in fact, if you talk about professional data like hype, what ordinary people can't understand is still incomprehensible.

Subconsciously, they still use the obvious data to compare.

To use a very simple analogy, it is often the party with the weakest data who dismantles the stage. Most people will think that you say that because you are weak. This is human nature.

It’s like asking an ordinary person, now you have 100 million, would you be willing to donate 90 million?

He will definitely answer, yes.

You ask him again, now that you have 10,000 yuan, would you be willing to donate 5,000 yuan?

He will answer, no.

Because he really has ten thousand yuan.

This is the naked gap, this is human instinct, you can't change it.

In this world, there are too few people who can look at problems rationally.

We had dinner with Mr. Yu and the others at Huawei. During the meal, Mr. Ren directly told Jiang Yanhai that he was paid twice as much as Mr. Lei's, 200 million!

To be honest, this number made Yinhu and Ye Cunxin, who also heard the conversation in the room, a little speechless, although they were expressionless.
