Pangu No. 1 chip: single-core (130nm process), main frequency 3.0Ghz, front side bus can reach 533Mhz, FSB 133Mhz, first-level cache 512KB (carbon crystal particles), second-level cache 3M (carbon crystal particles).

Pangu No. 2 chip, dual-core (130nm process), each core frequency 3.0Ghz, front side bus can reach 533Mhz, external frequency can reach 133Mhz, first-level cache 512KB (carbon crystal particles), second-level cache (dual-core common) 12M (carbon crystal particles).

Laymen watch the excitement, while experts watch the doorway.

To look at the performance of the chip, in addition to looking at the main frequency, the most important thing is to look at the process of the chip and other data.

When everyone saw that the chip was actually made of 130nm, they were actually a little disappointed.

Because now Intel is popularizing the 90nm process, and the 110nm process chips are only used in low-end products.

From this point of view, there is still a huge gap between the chips designed by Changtian Technology and the chips produced by Coastal Semiconductor and Intel.

Because Intel's 130nm chip was last used in large quantities in 2003.

As early as the Pentium III era, the 130nm process was Intel's mainstream technology.

But from this point of view, the gap between domestic chips and Intel should be 5 to 6 years.

But the professionals in the audience immediately saw the difference in Pangu chips.

First of all, the first-level cache and second-level cache of the Pangu No. 1 chip turned out to be carbon crystal particles.

And the secondary cache has reached three megabytes.

what does that mean?

It means that the chip will have a larger data storage pool.

It also means that the chip will get data and give data faster.

The storage speed of carbon crystal particles is several times or even dozens of times that of traditional storage materials. Everyone knows this concept.

Therefore, the professionals at the scene never thought that Changtian Technology would apply this technology to the 1st and 2nd level caches of the chip.

A person in charge of HP who came to the press conference nodded and chatted with his colleagues in English, saying, "From this point of view, the Pangu chip should be designed and produced by the Xia people themselves."

"They changed the level 1 and level 2 caches in a very clever way. The purpose should also be to make up for the lack of chip manufacturing process and computing power, and to increase the speed of reading and writing data on the chip."

"Changtian Technology is really a terrible company! According to this momentum, it may surpass Intel and AMD in a few years."

But in fact, the most surprising thing about being a human being is the Pangu No. 2 chip.

Wu Jun said: "Our Pangu No. 2 chip adopts a dual-core design, that is, two chip cores work, and we will use a second-level cache at the same time, which can increase the speed of chip capture and output data, so as to Increase the performance of the chip!"

At this time, everyone discovered that the second-level cache of the Pangu No. 1 chip was actually 3M, and the second-level cache of the Pangu No. 2 chip was actually 12 megabytes!

The second-level cache of the chip is not as big as possible, because the size of the chip is small, and your cache is bigger. When the chip calculates quickly and grabs the output data, it is very likely that there is no way to put the data in every One data channel, so the speed of the chip will slow down due to the increase of the second-level cache.

However, if the material of the L2 cache you use is very special, so that the chip can find all the read and write data channels in one go, then making your L2 cache larger will have obvious advantages in improving the performance of the chip.

Intel's current L2 cache is only 512K.

Changtian Technology actually reached 12 trillion.

What the **** kind of technology is this? !

What surprised everyone the most was the Pangu No. 2 chip, which actually used a dual-core design.

So far, this kind of design has never appeared in the chip design of commercial computers. The design of Changtian Technology is definitely ahead of its time.

Dell's representative looked at the basic data of the Pangu No. 2 chip, was greatly surprised, and directly contributed 150 points of influence.

Dell's representatives are also computer experts. They know that dual-core processors are not just two CPUs put together.

Rather, there are rather complex production and manufacturing processes.

Because the two processors have to work together to process different data at the same time without fighting each other, and feed back the processed data to the computer and users.

This is not a simple addition like 1+1=2.

Only a super chip design capability can design a dual-core chip.

Dell representative Karev told his colleagues: "We won't talk about the Pangu No. 1 chip. Looking at these data, it should be able to reach the level of the Intel Pentium III mid-range chip. But if there is a carbon crystal cache bonus, plus other With the optimization of hardware and Firefly OS, it should not be a big problem to achieve the performance of the current mainstream low-end CPUs.”

"Look at that Pangu No. 2 dual-core processor. I think its main frequency is only 3.0Ghz, but it uses a 12-megabyte L2 cache, and two cores work at the same time. This performance may be comparable to Intel's high-end Chips are comparable."

Karev quickly took out his mobile phone, recorded the specific data of the chip, and immediately sent the data back to Dell Yanjing headquarters.

Karev keenly felt that the dual-core era of chips should come.

When the design and production of chips cannot get rid of Moore's Law, adopting dual-core design will be the only way to improve the performance of chips for a long time in the future.

Dell has been paying attention to the replacement of chips. ???

Dell's executives, especially Dell's senior engineers, have been thinking about whether Intel will come up with a dual-core chip first or amd will come up with a dual-core chip first.

Gu did not expect that it was not the two traditional chip companies that produced the dual-core chip in the end, but the Yanjiang Semiconductor Company of Xiaguo.

Of course, the design is still Changtian Technology.

Some journalists who are not very tech-savvy are starting to get disappointed.

"It's actually a 130nm process, and the technical level is not very high."

"There are some small disappointments, and there is still a big gap between Intel and Intel, but I am still satisfied, after all, we are also capable of designing and producing computer chips."

However, those who know technology, including representatives of several computer companies and the big wholesaler in Huaqiangbei, did not make any comments at this time, but were waiting for Wu Jun's further explanation.

Chips do have high and low performance.

But a computer is a complex. It doesn't mean that your chip has strong performance, but the overall performance of the entire computer is strong.

Rather, there are many factors that are jointly constrained by variables.

So if you don't comment at this time, you are looking forward to the Pangu No. 2 dual-core chip.

At this time, Wu Jun said with some regrets: "When I was chatting with my colleagues in the chip laboratory of Changtian Technology, I actually learned that the chip design process of Changtian Technology has reached 65 nanometers, just because it is restricted by the current Yanjiang Semiconductor Technology Co., Ltd. The company's production technology, so we can design my nano-chip, but there is no way to produce it."

"In order to improve our chips and other budget capabilities, we used dual-core technology on the high-end Pangu No. 2 chip, the purpose is to learn from each other's strengths."

When this was said, the audience was even more shocked.

"Changtian Technology can actually design a 65-nanometer chip? What a joke!"

"65 nanometers? Isn't Intel's most advanced technology 65 nanometers? And it's not yet ready for mass production! I didn't expect Changtian Technology's chip design technology to be so strong!"

Everyone in the audience was in disbelief.

The surprise brought to them by Changtian Technology is far more than just Pangu No. 1 or Pangu No. 2.

In the entire chip industry chain, every link is very important, and the design link is the commander-in-chief of all links.

If a chip is poorly designed, no matter how good your production technology is, there is no way to produce an excellent chip.

If the person in charge of another company stood on the stage and said this, everyone would never believe it.

Because chip design is a comprehensive subject that requires long-term accumulation and continuous improvement to achieve results.

So whoever says that I have a 65nm chip design will definitely be laughed at and cast aside by everyone.

But Wu Jun said this, and Wu Jun said it on behalf of Changtian Technology.

From the birth of Changtian Technology to the present, every promise made by Changtian Technology has been fulfilled by him in the end.

In other words, Changtian Technology never brags!

Wu Jun didn't talk nonsense, and said directly: "So what is the performance of the domestic computer built with our Pangu chip? Is there a computer with the same configuration equipped with a well-known international brand chip that has better performance?"

Wu Jun said very seriously: "I don't count what I say, the data has the final say, and the test has the final say!"

Wu Jun asked the staff to turn on the two hosts at the same time.

After booting, two kinds of desktops appeared on the left and right sides of the big screen.

The one on the left is Yinghuo OS, and the one on the right is the classic windows, XP.

Wu Jun said ~lightnovelpub.net~ The host of the desktop link on the left is our Shenzhou T1 Jiaolong series equipped with the Shenzhou-2 chip.

The host on the right is a compatible machine with a high configuration.

This compatible machine uses the most advanced Intel Pentium 4 commercial chip with a main frequency of 3.8Ghz, and uses Intel's latest chip architecture. "

Wu Jun clicked on the relevant properties of the compatible machine, and the hardware information such as chip, memory, and hard disk appeared.

The chip is Pentium 4 3.8Ghz, the memory is Kingston 2G, the hard disk is Seagate 120, and the motherboard is produced by ASUS, which is the top motherboard of this model.

After showing the signal of the compatible machine.

Wu Jun arranged staff to use the professional software recognized on the market to test computer performance, and click the test.

Three minutes later, the test results of the two computers appeared on the big screen.

The result made everyone unbelievable.

With 100 points for the test, the comprehensive score of the Jiaolong computer is 88 points, while the score of the Pentium 4 processor compatible machine is 80 points.

In terms of comprehensive performance, Jiaolong Computer wins!

The audience was shocked!
