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 clocked at 3.0Ghz, the front-side bus can reach 533Mhz, the FSB can reach 133Mhz, the first-level cache 512KB (carbon crystal particles), the second-level cache (common for dual cores) 12M (carbon crystal
particles).
A layman watches the excitement, an expert watches the door.
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 chip's process and other data.
When everyone saw that the chip was actually produced using a 130nm process, they were actually a little disappointed.
Because Intel is now popularizing the 90nm process, 110nm process chips are only used in mid- to 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 Yanjiang Semiconductor Company and Intel.
Because Intel's 130nm chips were last widely used in 2003.
As early as the Pentium III era, the 130-nanometer process was Intel's mainstream technology.
But from this perspective, the gap between domestic chips and Intel should be 5 to 6 years.
But the professionals in the audience immediately saw what was different about Pangu chips.
First of all, the first-level cache and the second-level cache of the Pangu 1 chip are actually made of carbon crystal particles.
And the second-level cache actually reached three megabytes.
what does that mean?
This means that the chip will have a larger data storage pool.
It also means that the chip will obtain 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 on site never thought that Changtian Technology would actually apply this technology to the chip's level 1 and level 2 cache.
A person in charge of HP who came to attend the press conference nodded and chatted with his colleagues in English: "It seems that the Pangu chip was designed and produced by Xia people themselves."
"They changed the level 1 and level 2 cache in a very clever way. The purpose should also be to make up for the lack of chip manufacturing process and computing power and increase the speed of the chip reading and writing data."
"Changtian Technology is indeed a very scary company! If this momentum continues, it may not take more than a few years to surpass Intel and AMD."
But in fact, the most surprising thing about being a human being is the Pangu No. 2 chip.
Wu Jun said: "Our Pangu 2 chip adopts a dual-core design, which means that there are two chip cores working, and we will use a second-level cache at the same time, which can increase the speed of the chip to capture and output data. In this way,
Increase chip performance!"
At this time, everyone discovered that the L2 cache of the Pangu 1 chip was actually 3 MB, and the L2 cache of the Pangu 2 chip was actually 12 MB!
The chip's L2 cache is not bigger, the better, because the size of the chip is very small. If your cache is larger, when the chip quickly calculates and captures the output data, it is very likely that there will be no way to put the data on each page very quickly.
A data channel, so the speed of the chip will slow down due to the increase in the second level cache.
But if the material of the second-level cache you use is very special, allowing the chip to find all read and write data channels in one go, then making your second-level cache larger will have obvious advantages in improving the performance of the chip.
What surprises everyone the most is the Pangu 2 chip, which actually uses a dual-core design.
So far, this kind of design has never appeared in the chip design of commercial computers. This design of Changtian Technology is definitely ahead of its time.
Dell's representative was greatly surprised when he looked at the basic data of the Pangu 2 chip, and directly contributed 150 points of influence.
These representatives from Dell are also considered computer experts, and they know that dual-core processors are not just about putting two CPUs together.
Rather, it has a rather complex production and manufacturing process.
Because the two processors need to work together, they can process different data at the same time without fighting each other, and feed back the processed data to the computer and the user.
This is not a simple addition of 1+1=2.
Only those with strong chip design capabilities can design dual-core chips.
Dell's representative Karev said to his colleagues: "We won't talk about the Pangu 1 chip. Looking at these data, it should be able to reach the level of Intel's 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 reach the performance of current mainstream mid- to low-end CPUs."
"Look at the Pangu 2 dual-core processor. I think although its main frequency is only 3.0Ghz, it uses a 12-megabit L2 cache and two cores work at the same time. This performance is probably comparable to Intel's high-end processor.
Chips are comparable."
Karev quickly dialed his cell phone, recorded the specific data of the chip, and immediately sent the data back to Dell's Yanjing headquarters.
Karev keenly felt that the dual-core era of chips should come.
When there is no way to escape Moore's Law in chip design and production, dual-core design will be the only way to improve chip performance for a long time in the future.
Dell has been paying attention to chip replacement.
Dell's top management, especially Dell's senior engineers, have been wondering whether Intel or AMD will come up with dual-core chips first.
Unexpectedly, it was not these two traditional chip companies that finally came up with the dual-core chip, but Xia Guo's Yanjiang Semiconductor Company.
Of course, the design is still Changtian Technology.
Some journalists who are not very technical are starting to get disappointed.
"It's actually a 130-nanometer process. The technical level is not very high."
"There are some small disappointments. There is still a big gap between us and Intel, but I am still satisfied. After all, we are capable of designing and producing computer chips."
However, industry insiders who understand technology, including representatives from multiple computer companies and wholesalers from Huaqiangbei, did not make any comments at this time, but were waiting for Wu Jun's further explanation.
Chips do have different levels of performance.
But a computer is a complex. It does not mean that the performance of your chip is strong, but the overall performance of the entire computer system is strong.
Rather, there are factors that are jointly restricted by many variables.
So if you don’t comment at this time, you just have expectations for the Pangu 2 dual-core chip.
At this time, Wu Jun said with some regret: "When I was chatting with my colleagues in Changtian Technology's chip laboratory, I actually learned that Changtian Technology's chip design process has reached 65 nanometers. This is just because of the limitations of today's Yanjiang Semiconductor
The company’s production technology means that we can design our nanometer chips, but we cannot produce them.”
"In order to improve the budget capabilities of our chips, we use dual-core technology on the high-end Pangu 2 chip. The purpose is to learn from each other's strengths and offset weaknesses."
The whole audience was shocked when he said this.
"Changtian Technology can actually design 65-nanometer chips? What a joke!"
"65 nanometers? Isn't Intel's most advanced technology 65 nanometers? And it's not yet mass-produced! I didn't expect Changtian Technology's chip design technology to be so strong!"
Everyone sitting in the audience felt unbelievable.
The surprises Changtian Technology brought to them were far more than just Pangu 1 or Pangu 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 not designed well, no matter how good your production technology is, you will not be able to produce excellent chips.
If the person in charge of another company stood on the stage and said this, no one would believe it.
Because chip design is a comprehensive subject, it requires long-term accumulation and continuous improvement to achieve results.
So if anyone says that I have a 65-nanometer chip design, everyone will definitely laugh at and spurn them.
But it was Wu Jun who said this, and Wu Jun said it on behalf of Changtian Technology.
From the birth of Changtian Technology to the present, every promise he made was finally fulfilled by him.
That is to say, Changtian Technology never brags!
Wu Jun stopped talking nonsense and said directly: "So what is the performance of domestic computers built with our Pangu chips? Are there any computers with the same configuration equipped with internationally renowned chips of a certain brand that have strong performance?"
Wu Jun said seriously: "My words don't count, 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 desktops appear on the left and right sides of the large screen.
The one on the left is Firefly OS, and the one on the right is classic Windows, XP.
Wu Jun said, "The host linked to the desktop on the left is our Shenchuan T1 Dragon series equipped with the Shenchuan No. 2 chip.
The host on the right is a compatible machine with 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 information about the chip, memory, hard disk and other hardware appeared.
The chip is Pentium 4 3.8Ghz, the memory is Kingston 2G, the hard drive 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 for staff to use professional software recognized on the market to test computer performance and click test.
Three minutes later, the test results of the two computers appeared on the big screen.
The result was unbelievable to everyone.
With a full test score of 100 points, the overall score of the Jiaolong computer is 88 points, while the Pentium 4 processor-compatible computer scores 80 points.
In terms of overall performance, Jiaolong Computer wins!
