Chapter 111 Dual Core Linkage Technology

In the midst of the controversy, Nebula Technology once again increased investment in research and development. After supplementing the scientific research personnel, the progress of Chang Gung 4 has accelerated a lot again.

The Chang Gung project team of the Nebula R&D Department managed to stabilize Chang Gung 4 by continuously adding cores when the astral structure was not perfect.

The ten-core design made Liu Dalang think of the famous rollover event in the history of MediaTek: the one-core was in trouble, and the nine-core onlookers made a big joke.

Chang Gung 4 is also a deca-core, not only a 3-core, but also a 20nm process technology, which is theoretically easier to overturn than a MediaTek chip.

MediaTek Helio X20 also uses a 20nm process technology, and has a three-cluster ten-core architecture, which divides tasks according to severity.

The astral structure is also divided according to the level of mission severity, and it is still a three-dimensional structure. Liu Dalang really has no confidence.

Theoretically speaking, the three-component and ten-core architecture is a good architecture, and the astral architecture is also a good architecture, and there is no problem in classifying tasks according to their severity.

But theory is theory after all. If you don’t practice it, you don’t know whether the chip is a good chip. Even the chip manufacturer can’t tell for sure.

Liu Dalang also experienced the hard work of developing the chip. During the tape-out process of Chang Gung 4, the waiting for each test was extremely difficult.

In the power consumption test, the power consumption of Chang Gung 4’s chip directly exploded. As a last resort, the Chang Gung project team had to overthrow the previous design and start over.

Strange to say, most of the overturned chips in history were folded on the 20nm process. Could it be that there is a problem with the 20nm process?

The Chang Gung project team did not believe in evil, and added the cores of Chang Gung 4 to twelve. To everyone's surprise, the twelve cores succeeded!
Liu Dalang:? ? ?

Chang Gung Project Team: ? ? ?

What's happening here?Liu Dalang suddenly understood why the Chang Gung project team told him that he didn't have a thorough understanding of the astral structure and dared not develop it.

NIL technology is also strange. In fact, they don't know that NIL technology is not suitable for research and development, and it is suitable for directly copying drawings.

From the name of NIL: nanoimprint technology, we know that this is a mass production method after the production of high-end chips, which will save costs.

Therefore, the best usage is to take the existing drawings of TSMC, Samsung, Intel and other manufacturers and directly improve them for mass production.

But the actual conditions do not allow it at all. Why do Samsung, Intel and other manufacturers provide their high-end chip drawings to Nebula Technology?

So what if it saves costs?People can produce it themselves, why should they hand it over to Xingyun Technology for OEM?Just to save costs?
Maybe it is possible!
Money touches people's hearts. If Nebula Technology's foundry can save them a considerable amount of cost, they might really give up the current model.

However, the distance between Nebula Technology and Samsung and Intel manufacturers is not only a matter of cost, but also some factors that cannot be ignored.

Therefore, Nebula Technology and these international manufacturers are destined to be competitors. If they want to cooperate, unless the Earth Alliance is established, it will be impossible.

The Chang Gung project team is also a group of ruthless people. They led a group of NPCs to design Chang Gung 4 with NIL technology, and the filming was successful!
Although this chip is a bit outrageous, it has two more cores than the MediaTek Helio X20. Will the [-]-core processor also have a problem with one core...

Liu Dalang hopes not. The advantage of Nebula Technology is here. It has its own technology and can conduct multiple experiments in chip development and design.

As for why the Samsung processor, which also has a chip production line, is so stretched, it is not known, it may be that the involution is too serious.

TSMC announced that it has broken through the 10nm process technology. Samsung saw it. Is this okay?Overnight, he also broke through his own technology to 10 nanometers.

In fact, everyone knows that Samsung's foundry technology was too eager for quick success and quick benefits later, and there were defects such as leakage, which made it difficult to compete with TSMC.

When producing chips with the same process technology, the chips manufactured by Samsung are completely inferior to TSMC in terms of transistor density and power consumption.

Many people have questioned whether Samsung's foundry technology has been falsely reported, and it is really falsely reported. Not only Samsung has falsely reported, but TSMC has also falsely reported.

Liu Dalang can't remember exactly when it started. He only knows that whether it is Samsung or TSMC, nanometers are just an imaginary number.

And the NIL technology of Nebula Technology is the real thing. The number of nanometers marked is exactly the number of nanometers. No wonder Chang Gung 4 can have twelve cores.

If the chip is manufactured according to the standards of Samsung and TSMC, ten cores must be enough, and twelve core chips cannot fit at all.

If it is placed on a tablet or a handheld, then it should be ignored. There are still requirements for the size of the mobile phone chip, otherwise the chip will heat up too much.

Qualcomm Snapdragon will produce a few Fire Dragons every one or two generations. Whether Android manufacturers like it or not, they have no choice but to bite the bullet and promote it.

If you are lucky, you will encounter a new generation of God U. If you are unlucky, it will be the same as the very confident Snapdragon 810 of Xiaomi Note, which cannot suppress the power consumption and heat.

Not only the Snapdragon 810, each generation of Snapdragon has some problems with power consumption, but some problems are big, and some problems are small so they are covered up.

If the Snapdragon 810 is replaced with the Snapdragon 835, how can anyone say that this is a generation of god U?They'll just think that's what a normal chip looks like.

Therefore, God U is all compared, including the so-called Kirin 9000, which is one generation and three generations. Is the experience really so good?
Maybe not?It's just that compared with Snapdragon 888, Kirin 9000 has its unique advantages, and this advantage just hits the pain points of users.

That's enough!
Major mobile phone manufacturers boast about the Snapdragon 870 every day, saying that it doesn’t heat up very much. In fact, buy one and use it to see if it has a fever?

It is no wonder that later consumers became more and more chip-only, and a premise is needed to refute the chip-only theory, that is, there is no problem with the chip itself.

Only when there is no problem with the chip, consumers will care more about appearance design, texture, image, screen, battery, fast charging, etc.

If the chip itself has problems, whether it is power consumption or performance, these cannot satisfy consumers. The chip is equivalent to the brain.
It's impossible!

After Chang Gung 4 tape-out was successful, the test team immediately summarized the measured data of Chang Gung 4, the most notable thing is the reduction in power consumption.

The power consumption of the 4-core Chang Gung 4 is 146% lower than that of the [-]-core Chang Gung [-]. This result, let alone Liu Dalang, can’t explain it, and no one can do it.

Perhaps Chang Gung 4 has found a way to enter high-end chips, which is to add more cores to the star architecture to maintain chip stability.

But what is the principle, they have not found out yet, of course, the stability of the chip is the first, follow-up research can be done slowly~

The R&D personnel of the Chang Gung project team really didn’t brag. After the test data of the Chang Gung 4’s engineering machine came out, it was really better than the Snapdragon 805.

Judging from the test data of the engineering machine, Chang Gung 4 has even reached the level of Snapdragon 808, and it is only a little lower than Snapdragon 810 in some tests.

However, the test data of the engineering phone will be better. After the mobile phone is mass-produced, due to factors such as design and parts increase, it will not perform as well as the tested engineering phone in all aspects.

These are normal situations, so on the whole, Chang Gung 4 will not be as good as Snapdragon 808 in mass production, but better than Snapdragon 805.

Of course, the premise of this comparison method is that Nebula Technology does not have dual-core linkage technology. In fact, Liu Dalang exchanged for dual-core linkage technology as soon as Chang Gung 4 tape-out was successful.

It costs a lot of points, but in Liu Dalang's view, the dual-core linkage technology is worth the price, because this technology can still be used in the future.

If Nebula Technology has a chip that can compete with Apple's M-series chips, and then use dual-core linkage technology, wouldn't it be a one-click ascend to heaven?
What will the M1 Ultra be then?No matter how powerful Apple's M-series chips are, how about their gaming performance?Nebula technology is not necessarily the same~

You must know that the market for gaming notebooks is very broad, especially in the case of graphics card shortages that will occur in a certain period of time in the future, you can only buy them at a higher price.

Whether it is a desktop computer or a notebook, countless consumers are willing to buy a high-performance gaming notebook despite the price increase.

What is it for?
Liu Dalang didn't know, and he didn't want to know, he only knew one thing, the replacement of computers was much faster than that of mobile phones.

Perhaps the graphics card that still needs to be purchased at a higher price will become garbage that no one cares about when it is sold out in less than two years, it is so cruel.

So when buying a laptop, especially a gaming laptop, Liu Dalang always believes that you should figure out your own needs before buying.

Because only students have the greatest demand for game books, every year some students tell their parents that they must have more than 1 top-end versions.

In fact, you can ask yourself, do you really need such an expensive computer?Electronic products are updated so quickly, what should we do if new ones are released?
Having said so much, it is because Liu Dalang saw the hope of Nebula Technology from the mobile phone industry to enter the PC terminal field based on Chang Gung 4.

After the mass production of Chang Gung 4 and the successful development of the astral architecture, the first thing Nebula's R&D department should do is to enter the computer CPU through the astral architecture.

This seemingly impossible thing is actually very possible, because NIL technology itself is a template technology, and it only needs to manufacture the chip according to the drawing or structure.

As for how it is manufactured, consumers don't care at all. What they care about is whether the products they buy can meet the expected standards.

Now that Chang Gung 4 has been developed, Liu Dalang will definitely not use Nvidia Tegra X1 customized version or Samsung Exynos 7420, but will choose to use Chang Gung 4 with dual-core linkage technology.

A single chip has a performance that exceeds that of the Snapdragon 805, and with the support of dual-core linkage technology, the two chips can completely achieve 1+1>2.

In terms of overall performance, the Chang Gung 4×2 can even be compared with the Snapdragon 820, and the power consumption is more stable, and the performance is even stronger!
When the time comes to face the media, it can be declared that the Chang Gung 4×2 has reached the 10nm standard, two 20nm = 10nm, no problem at all!

In fact, this equation is not valid, because the dual-core linkage technology is not a simple chip superposition, and the principles involved are very complicated.

It also has a very important premise, that is, the two chips using dual-core linkage technology must have low power consumption and be stable enough overall.

Otherwise, no matter how many chips are superimposed, it is meaningless. If ten or eight chips are superimposed, the mobile phone will not be able to withstand the heat before it is used.
