i have an electronics factory

Chapter 194 lv.80
It can be said that the Changhe 4 chip has been in preparation since the end of last year, from the 6-core version to the 9-core version at the beginning, and then returned to the 6-core version, and the 28-nanometer process technology is no problem at all.

Comparing the chip in Chen Zifan's memory horizontally and the running score data, the Changhe 4 can already run a score of 10+ in the extreme test on the mobile phone, but it is a pity that it is not enough to carry a 2k screen.

If you want to perfectly drive 2k + high resolution + high resolution games + high frame rate + high resolution + 60 frames of 1080p video... and put it in such a small space as a mobile phone, you must have a running score of at least 60.

Not only the performance of the chip is strong enough, but also the power consumption level is very good. If it can achieve a power consumption of about 4W, then it is almost a perfect mobile phone.

Fortunately, mobile games at this stage do not have such high requirements for chips, and various software are not so perverted.

Including the demand for storage is not as big as later, why is the storage of later Android phones generally more than 12GB?Some even achieved 16GB, plus what 8GB storage expansion...

One of the reasons is that the software puts too much pressure on it. The current APP has only one function, and the later APP... has small programs, live broadcasts, advertisements, and games. Can the requirements be low?
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 capacity of Stardust 3+ is about 3GB, which is quite enough in this year. After all, it has the blessing of Stardust OS, which is not as bloated as Android system, and a little lower storage capacity is enough for use.

The core area of ​​the Stardust factory is a little different from the last time Chen Zifan came. There are some new faces. At the same time, the equipment and production lines look more regular, which is very helpful for improving 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 Changhe 4. After our actual measurement, it has reached a very ideal state. Its single and multi-core frequency..."

Chen Zifan nodded. To be honest, he is not very interested in these data. The architecture of Changhe 4 determines that it is different from conventional chips. It measures single core... As long as there is a need, 6 cores are equivalent to 1 core.

The multi-core score also belongs to the normal level of 10+ running points. For example, the running score of the first-generation cost-effective Snapdragon 660 is about 18 points, and Changhe 4 is relatively worse, but the two chips are not products of the same era at all. , nothing comparable.

长河4比骁龙660早了将近8年时间，星尘科技只需要再来1～2代产品就可以很轻易地超越这颗中端神U。

At the same time, this also cut off the possibility of Qualcomm developing into a chip giant according to the 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 bit dry. but.

At any rate, MediaTek has the technical authorization of Stardust Technology... It's a pity that with the son of Haihua Chip, MediaTek's power is getting weaker and weaker.

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

After listening to the general manager's report, Chen Zifan asked: "According to the current progress, when will Changhe 4 be able to complete the test package and start mass production?"

"As soon as possible, it will be in mid-July!"

"It doesn't have to be the fastest, we must make sure that our chips have no problems, and quality comes first."

"understood."

Under the leadership of the person in charge, Chen Zifan also took a look at the sample chip of Changhe 4... just looking at the parameters and blueprints, he didn't feel much. After taking a look in his hand, he found that the chip technology of Stardust Technology was a bit crooked...or the chip technology of Stardust Technology Chip is the right model?

But this is impossible to verify.

I saw that the Changhe 4 in his hand is completely different from the flat chip on the Android phone. It is more like a "cube", divided into upper and lower layers, each layer has 3 cores, and the size of the 6 cores is exactly the same.

But you can't tell from the outside.

There is a layer of black paint on the outside, and the bottom part is densely packed with contacts. The difference in chip structure directly affects the design of the motherboard, and also has a certain impact on the internal design of the Stardust phone.

But anyone who has ever dismantled a Stardust phone, no matter if it is Stardust 1 or Stardust 3+, the inside of the fuselage is unbelievably tidy, just looking at it makes people feel pleasing to the eye, and it is also convenient for maintenance personnel to replace accessories.

There is not only one version of Changhe 4 this time, Changhe 4 is the standard version, but there is also a higher specification Changhe 4+, which has been adjusted in the core frequency and will be used in models with stronger performance release.

There are also dedicated chips for tablet computers, smart watches, drones and other products.

The Haihua chip will fully inherit Changhe 3, and use the low-end chips subdivided by Changhe 3 to continue to build low-end smart phones, which will be used in low-end models such as Meilan and Redmi, to create smart phones for all The times have worked hard, as for the mid-priced models...

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

After briefly confirming the progress of the chip, Chen Zifan came to his workshop in the core area again, and began to determine the specific configuration of Stardust 4 and Stardust 4+. point of:
How to make the difference between 4 and 4+?
Stardust 4+ is 4 yuan more expensive than Stardust 2000, so where is the 2000 yuan more expensive?
Needless to say, in terms of imaging, 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 with Stardust 3, it also has a very large improvement.

After all, it has been two years, and it must be equipped with a dual camera. The fingerprint recognition that Stardust 3 does not have, Stardust 4 must also be arranged, but there is no ultrasonic fingerprint, only the same model on the Stardust 3 + under-display optical fingerprint.

This is also a small difference.

The ultrasonic fingerprint of Stardust 4+ must be more "high-end", but anyone who is really knowledgeable knows that the cost of optical fingerprint and ultrasonic fingerprint is not much different, and there is not that big difference in actual use.

Can you really feel it in just a few seconds?

Or unlock with wet hands?

Even if you can unlock the screen with wet hands, if you want to click on a certain software, it will cause various false touch problems.

One of the advantages of ultrasonic fingerprint 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 vivo.

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

The battery of Stardust 4 is relatively smaller. In order to ensure battery life (make a difference), it will use a refresh rate of 90hz. There are not so many restrictions on Stardust 4+, and the refresh rate of 120hz is no problem.

However, Stardust Technology will not be like Apple. The 60hz screen will remain unchanged for thousands of years. After the battery capacity of the next-generation Stardust 5 is increased, Stardust 5 and Stardust 5+ will uniformly use high refresh screens, and no distinction will be made. .

In terms of fast charging, the two models are consistent, both are 50W fast charging, and both are "true" full blood version. Since 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 50W wireless charging. This time, the wireless charging is also greatly improved. Compared with the previous 30W wireless charging, the charging speed is almost doubled.

On the front camera, the Stardust 4+ will also unlock some "new technologies". Although it is both a front-facing single camera, the Stardust 4+ will have more hidden sensors.

The last is the appearance + brand premium. Chen Zifan still remembers the original Stardust 1, which obviously used a 4.8-inch small screen, but was called a "big-screen phone" by countless consumers. Now it seems... can only be called a smartphone The development of the industry is constantly breaking the inherent concept.

The 5.4-inch Stardust 3 has begun to be disliked by some people for its small screen. Even if it feels really good in the hand, it is also very small and delicate, and it is not enough.

If you look at Apple's mini series, you will know that there are very high voices on the Internet every year, but the actual sales are very poor. Many people with high voices will not buy it.

Fortunately, there is no such problem with Stardust mobile phones at present, and the size of mainstream mobile phones is also 5-6 inches, so there is no problem in continuing to use 4 inches for Stardust 5.4, and it can even be used for several generations of products.

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

It's not real 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. It is definitely impossible to use the plain leather material on the Stardust 4+. Finally, there will be a more "technical" one. The style 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 be unacceptable. It depends on how consumers choose. If it is Chen Zifan, he will definitely choose a cheaper one.

As for the Stardust-Yao Soul, as a "mass-produced concept machine", in addition to air charging, it will also be equipped with some brand-new technologies. After confirming the specific parameters, Chen Zifan started to initiate the document.

These documents were immediately passed on to the various subsidiaries, and they would produce the required accessories according to Chen Zifan's requirements, and send them to the Stardust Factory for assembly and production.

Then just be patient and wait.

Regarding the remaining products, Chen Zifan still has to think about it for a while. He is actually very interested in AR glasses. After finishing the work on the three new models, he contacted Zhao Wushang and asked him to find some specialized Supplier responsible for lens production to cooperate.

Why not look for eyewear brands…

At present, few domestic eyewear brands have their own technology, and the profit of lenses is very high. Some unscrupulous brands can even achieve an overall profit rate of more than 200%, which is an exaggeration.

The purpose of finding a lens supplier to cooperate is to save time, and by the way, to expand new business for Stardust Technology. The reason is also very simple. Based on the current domestic situation, more and more consumers wear glasses.

Chen Zifan has read the survey report of Haicheng in 2012. The rate of spectacles in elementary school is 28.7%, that in junior high school is 39.6%, and that in high school has exceeded 50%, reaching an exaggerated 52.4%. Moreover, myopia is theoretically irreversible. There is no way to take it off.

Then there was laser surgery...

However, Chen Zifan always has reservations about vision correction surgery. Since the proportion of people wearing glasses is increasing significantly, it is impossible for AR glasses to be sold only to consumers who do not wear glasses. versions.

But this version needs to be customized...

The price may be slightly more expensive.

In addition, Chen Zifan is still waiting for a more important matter. The current level of [Stardust Technology] is lv.78. 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, [Stardust Technology] can unlock a higher level of [Stardust Blueprint] after reaching lv.80. The blueprint also contains some key technologies in construction and power generation.

The second is [Analysis of Shanzhai] and [Synthetic Creation] of materials. This is a brand new breakthrough. [Stardust Technology] has only been able to analyze and "electricity" or products derived from "electricity" before.

Such as operating system etc.

But trying to analyze stone and steel is a bit difficult. Of course, these basic materials are not important. What Chen Zifan lacks are various high-end materials, which he needs to use in products such as cars and mobile phones.

Even the heat dissipation of mobile phones, tablet computers, and future notebook computers requires some new materials, which can be used as gimmicks and enhance product strength.

During the waiting period, the influence of the Stardust press conference reached a new height under the ferment of public opinion. From Stardust-Chenji to Xinghan 001, the enthusiasm of countless consumers was all ignited, and there were still a lot of Stardust The user goes to the local Stardust after-sales center.

It's not that their mobile phone is broken, but that they heard that Stardust mobile phone can be replaced with a new sodium-lithium battery for free. The capacity and battery life have been greatly improved, and the charging speed has also become faster.

The role of the Stardust after-sales center is reflected. It is not only used to repair mobile phones, but also to solve various after-sales problems, such as receiving mobile phone cases at a fixed time every month.

Another example is free stickers and so on.

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

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