Changhe4This chip can be said to have been preparing since the end of last year, from the beginning of the 6-core version→ 9-core version, and later back to the 6-core version, and the 28nm process technology is completely fine.

Horizontally comparing the chip in Chen Zifan's memory, as well as the running score data, Changhe 4 can already run 100,000+ scores under the extreme test on the mobile phone, but unfortunately it is not enough to use it with a 2K screen.

Want to perfectly drive 2K + high brush + high resolution game + high frame rate + high pixel + 60 frames 1080p video... And it has to be placed in such a small space as a mobile phone, and the running score must be at least more than 600,000.

Not only the chip performance must be strong enough, but the power consumption level must also be very good, if it can achieve about 4 power consumption, then it is almost the best mobile phone.

Fortunately, the requirements for chips in mobile games at this stage are not so high, and various software are not so perverted.

Including the demand for storage is not as great as later, why is the storage of Android machines generally more than 12GB later? Some even do 16GB, and what 8GB of memory expansion is added...

One of the reasons is that the pressure on the software is too great, and the current APP has only one function, and the later APP... There are mini programs, live broadcasts, advertisements, and games, can the requirements not be high?

But this is also a trend of development, and there will definitely be more and more things that an APP can do.

At present, the storage of Stardust 3+ is about 3GB, which is very enough in this year, after all, it is blessed by Stardust OS, not as bloated as the Android system, and the storage is enough to use a little lower.

The core area of the Stardust Factory is a little different from the last time Chen Zifan came, there are more new faces, and the equipment and production line look more organized, which is very helpful to improve efficiency.

The person in charge immediately came out after receiving Chen Zifan's news, and also took a detailed data:

"Chen Dong, this is the final plan of the current Changhe 4, and it has reached a very ideal state after our actual measurement, its single-core and multi-core frequencies..."

Chen Zifan nodded, to be honest, he didn't have much interest in these data, the architecture of Changhe 4 determines that it is different from conventional chips, testing a single core... As long as there is a need, 6 cores is equivalent to 1 core.

The multi-core score also belongs to the normal level of 100,000+ running scores, for example, the running score of the generation of cost-effective god U Snapdragon 660 is about 180,000 points, and the Changhe 4 is relatively poor, but the two chips are not products of the same era at all, and there is no comparison.

Changhe 4 is nearly 8 years earlier than Snapdragon 660, and Stardust Technology only needs 1~2 more generations of products to easily surpass this mid-range God U.

At the same time, this also cuts off the possibility of Qualcomm developing into a chip giant according to its original history, at least in terms of mobile phone chips, Qualcomm has no chance to catch up with Stardust Technology, not to mention that they are still in their infancy, and even MediaTek is a little unable to do it.

Fortunately, MediaTek has the technical authorization blessing of Stardust Technology... It's a pity that after having the son of Haihua chip, MediaTek's power is getting weaker and weaker.

The main market they are targeting has also become their or foreign mobile phone manufacturers, such as HTC, LG and other brands, Samsung must not have to think about it, Samsung has a big business, and it is impossible to use their chips.

After listening to the report of the general manager, Chen Zifan asked: "According to the current progress, when will Changhe 4 complete the test packaging and start mass production?"

"Soonest, in mid-July!"

"Not the fastest, we must make sure that there is no problem with our chips, and quality is the first."

"Understood."

Chen Zifan, under the leadership of the person in charge, also took a look at the sample chip of Changhe 4... Just looking at the parameters and drawings, he didn't feel anything, but when he took it in his hand, he found that the chip technology of Stardust Technology was a little crooked... Or is Stardust Technology's chip the right model?

But there is no way to verify this.

I saw that the Changhe 4 in his hand is completely different from the flat chip on the Android machine, it is more like a "cube", divided into two layers, each layer has 3 cores, and the size of the 6 cores is all

Same.

But it's certainly not visible from the outside.

The outside is made of a layer of black coating, and the bottom is densely packed with contacts, and the difference in chip structure has the most direct impact on the motherboard design, and it also has a certain impact on the internal design of the Stardust mobile phone.

But as long as the person who has dismantled the Stardust mobile phone, whether it is Stardust 1 or Stardust 3+, the inside of its fuselage is neat and tidy, just looking at it makes people feel pleasing to the eye, and it is also convenient for maintenance personnel to replace accessories.

This time, there is not only one version of Changhe 4, Changhe 4 is the standard version, and there is also a higher specification Changhe 4+, which has made certain adjustments in the core frequency, and will be used in models with stronger performance.

There are also special chips for tablets, smart watches, drones and other products.

Haihua chips will fully inherit the Changhe3, and continue to build low-end smart machines with the low-end chips subdivided by the Changhe3, which will be used in low-end models such as Meizu Blue and Redmi, and contribute to building the era of national smartphones.

At the end of this year, mobile phone brands in this range will use Haihua chips to create a mid-range performance core, which is equivalent to 80% of the Changhe 3, and there is also a Changhe 3 replacement chip, which is very cost-effective.

After briefly determining the progress of the chip, Chen Zifan came to his work room in the core area again, and began to determine the specific configuration of Stardust 4 and Stardust 4+, the main configuration is nothing to say, it is nothing more than those few, but now there is a more difficult point:

How do you make a difference between 4 and 4+?

Stardust 4+ is 2,000 yuan more expensive than Stardust 4, so where should the 2,000 yuan be expensive?

Needless to say, in terms of image, Stardust 4+ will continue the three-camera design of Stardust 3+, and further improve the specifications, but Stardust 4 is not easy to mess with, compared to Stardust 3 There is also a very big improvement.

After all, it's been two years for a pigeon.,You must have a double camera.,Stardust 3 doesn't have fingerprint recognition,Stardust 4 also has to be arranged,But there is no ultrasonic fingerprint,Only Stardust 3+The same under-screen optical fingerprint。

That's a small difference.

The ultrasonic fingerprint of Stardust 4+ must be a little more "high-end", but those who really know know that the cost of optical fingerprint and ultrasonic fingerprint is not much different, and there is not so much difference in actual use.

How many seconds can you really feel it 0.0 seconds?

Or wet hands unlocking?

Even if you can unlock the screen with wet hands, trying to click on a certain software will cause all kinds of mistouch problems.

One of the things that ultrasonic fingerprint is really easy to use is that its recognition area is large enough, but not every mobile phone equipped with ultrasonic fingerprint has a large recognition area, as far as Chen Zifan knows, Meizu's is relatively small.

The biggest should be VVO.

The difference between fingerprints alone is certainly not enough, the rest is the screen size, Stardust 4 is still 5.4 inches, Stardust 4+ is 6.4 inches, it is the same in terms of resolution, but it can be operated in terms of refresh rate.

The battery of Stardust 4 is relatively smaller, in order to ensure battery life (make differences), so a refresh rate of 90 will be used, Stardust 4+ There are not so many restrictions, and there is no problem with the refresh rate of 120.

However, Stardust Technology will not be like Apple, 60The screen will remain unchanged for 10,000 years, and the battery capacity of the next generation Stardust 5 will be increased, Stardust 5 and Stardust 5+ will be unified with a high brush screen, and no further distinction will be made.

In terms of fast charging, the two models are the same, both are 50 fast charging, and they are both "true" full blood versions, because the battery of Stardust 4 is relatively small, the theoretical charging time is likely to be within 30 minutes.

Wireless charging is also standard, and it will also be upgraded to 50 wireless charging, this time the wireless charging improvement is also very large, and the charging speed is almost double compared to the previous 30 wireless charging.

On the front camera, Stardust 4+ will also unlock some "new technologies", although it is the same front single camera, but Stardust 4+ will have more hidden sensors.

Finally, it is the appearance + brand premium, Chen Zifan still remembers the Stardust 1 at the beginning, which obviously used a 4.8-inch small screen, but it was called a "giant screen mobile phone" by countless consumers

Now it seems... It can only be said that the development of smartphones is constantly breaking the inherent concept.

The 5.4-inch Stardust 3 has begun to be disliked by some people The screen is small, even if it feels really good, it is also very small and exquisite, and it is a bit insufficient.

If you look at Apple's series, the demand on the Internet is very high every year, but in fact the sales are very bleak, and many people with high voices will not buy it.

Fortunately, there is no such problem in Stardust mobile phones, and the size of mainstream mobile phones is also 5~6 inches, so Stardust 4 continues to use 5.4 inches without any problem, and even several generations of products can be used.

In the selection of materials for the back cover, Stardust 4 is divided into two materials: glass, plain leather, which are also the two most common and popular back cover materials, Stardust 4+ The back cover material is more fierce, the same glass material, Stardust 4+ will be done towards the "jade".

It's not really jade, it's enough to make a feeling.

The wood will still be retained, and the ebony will be replaced with another wood of the same specification, with a wooden back cover, and the plain leather material will definitely not be used on Stardust 4+, and finally there is a stronger style with a "sense of technology", which is somewhat similar to the design of Stardust-Chenji.

Coupled with the brand premium of Stardust Technology, the price difference of 2000 yuan will not make people feel unacceptable, it depends on how consumers choose, if it is Chen Zifan, he will definitely choose a cheaper one.

As for Stardust-Yaoluo, as a "mass production concept machine", in addition to air charging, it will also be equipped with some new technologies, and after determining the specific parameters, Chen Zifan began to issue documents.

These documents were transmitted to each subsidiary as soon as possible, and they will produce the required accessories according to Chen Zifan's requirements, and send them to the Stardust Factory, which will assemble and produce them.

All you need to do is be patient.

Regarding the remaining products, Chen Zifan still has to think about it for a while, he is personally quite interested in AR glasses, after solving the work of the three new machines, he contacted Zhao Wuxian and asked him to find a few suppliers who are specifically responsible for lens production to cooperate.

Why not look for eyewear brands...

At present, few domestic glasses brands have their own technology, and the profit of lenses is very high, and some unscrupulous brands can even achieve an overall profit margin of more than 200%, which can be imagined.

The purpose of cooperating with lens suppliers is to save time, and by the way, to expand new business for Stardust Technology, the reason is also very simple, as far as the current domestic situation is concerned, there will be more and more consumers wearing glasses.

Chen Zifan has read Haicheng's 2012 survey report, the glasses rate in primary schools is 28.7%, the glasses rate in junior high schools is 39.6%, and the high school has exceeded 50%, reaching an exaggerated 52.4%, and myopia is theoretically irreversible, and you can't take it off if you wear it.

But then there was laser surgery...

However, Chen Zifan has always had reservations about the surgery to correct his vision, since the proportion of wearing glasses is increasing significantly, AR glasses cannot only be sold to consumers who do not wear glasses, and they must cater to mass consumers and specially release a version for the myopic eye group.

However, this version needs to be customized...

The price may be slightly more expensive.

In addition, Chen Zifan is still waiting for a more important thing, the current level of [Stardust Technology] is lv.78, and according to the current progress, it will take about half a month to upgrade to lv.80.

Judging from the information that Chen Zifan has already learned, after [Stardust Technology] reaches lv.80, he can unlock a higher level of [Stardust Blueprint], and the drawing also contains some key technologies in construction and power generation.

The second is the [analysis copycat] and [synthesis creation] of materials, which is a new breakthrough, [Stardust Technology] has only been able to analyze and "electricity" or "electricity" derived products before.

For example, the operating system, etc.

But if you want to analyze stone and steel, it's a bit uneasy, of course, these basic materials are not important, Chen Zifan lacks a variety of high-end materials, he needs to use materials in cars, mobile phones and other products.

Even mobile phones, tablets, the future

The heat dissipation of laptops requires some new materials, which can not only be used as a gimmick, but also improve product power.

During the waiting period, the influence of the Stardust press conference rushed to a new height under the fermentation of public opinion, from Stardust-Chenji to Xinghan 001, the enthusiasm of countless consumers was all ignited, and a large number of Stardust users went to the local Stardust after-sales center.

It's not that their mobile phones are broken, but I heard that Stardust mobile phones can be replaced with new sodium lithium batteries for free, and the capacity and battery life have been significantly improved, and the charging speed has become faster.

The role of the Stardust after-sales center is reflected, it is not only used to repair mobile phones, all kinds of after-sales problems can be solved here, such as receiving mobile phone cases at a fixed time every month.

Another example is free film and so on.

The curved screen of Stardust Technology can't be pasted by ordinary people, so it is better to let the after-sales personnel operate it.

Chen Zifan spent so much money to cover the country's after-sales service, which played a huge role, and many Stardust users who bought mobile phones online also experienced what the offline service of the Stardust after-sales center was like for the first time.
