It can be said that the Changhe 4 chip has been in preparation since the end of last year. From the 6-core version at the beginning to the 9-core version, and later back to the 6-core version, the 28nm process technology is no problem at all.
Comparing the chips in Chen Zifan's memory and the running score data, Changhe 4 can already run a score of 100,000+ on a mobile phone under extreme tests, but it is a pity that it is not enough for a 2k screen.
If you want to perfectly drive 2k + high brush + high-resolution games + high frame rate + high pixels + 60 frames of 1080p video recording... and it also needs to be placed in such a small space as a mobile phone, the benchmark score must be at least over 600,000.
Not only does the chip performance have to be strong enough, but the power consumption level must also be very good. If it can achieve a power consumption of about 4W, then it will be almost a perfect mobile phone.
Fortunately, mobile games at this stage do not have so high requirements for chips, and various software is not so abnormal.
Including the demand for storage is not as big as it was later. Why do later Android machines generally have more than 12GB of storage? Some even have 16GB, and what kind of 8GB storage expansion is needed...
One of the reasons is that the pressure on software is too great. Today's APPs only have one function. Later APPs... have small programs, live broadcasts, advertisements, and games. Can the requirements not be too high?
But this is also a trend of development. An APP will definitely be able to do more and more things.
The current memory of Stardust 3+ is about 3GB, which is quite sufficient in this year. After all, it is supported by Stardust OS, which is not as bloated as Android system. A lower memory is enough for use.
The core area of the Stardust Factory is a little different from the last time Chen Zifan came here. There are some new faces. At the same time, the equipment and production lines also look more organized, which is very helpful for improving efficiency.
The general manager came out immediately after receiving the news from Chen Zifan, and also got a detailed data:
"Dr. Chen, this is the final solution for Changhe 4. After our actual testing, it has reached a very ideal state. Its single and multi-core frequencies..."
Chen Zifan nodded. To be honest, he was not very interested in these data. The architecture of Changhe 4 determines that it is different from conventional chips. When testing a single core... as long as there is a need, 6 cores are equivalent to 1 core.
The multi-core score is also within the normal level of 100,000+ running points. For example, the first-generation cost-effective Snapdragon 660 has a running score of about 180,000 points. The Changhe 4 is relatively worse, but the two chips are not products of the same era at all.
, there is no comparison.
Changhe 4 is nearly 8 years ahead of Snapdragon 660. Stardust Technology only needs 1 to 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 the initial stage, and even MediaTek is a bit dry.
but.
At any rate, MediaTek has the technical licensing support of Stardust Technology... It is a pity that after having Haihua Chip as its biological son, MediaTek's power has become weaker and weaker.
The main market they are targeting has also become their own or foreign mobile phone manufacturers, such as HTC, LG and other brands. Samsung must not have to think about it. Samsung is a big company and it is impossible to use their chips.
After listening to the report from the general manager, Chen Zifan asked: "According to the current progress, when can Changhe 4 complete testing and packaging and start mass production?"
"At the soonest, it will be ready in mid-July!"
"We don't have to be the fastest. We must make sure there are no problems with our chips. Quality is the first priority."
"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, the drawings didn't make sense. When he took it into his hand, he found that Stardust Technology's chip technology was a bit crooked... or rather Stardust Technology's.
Chip is the correct model?
But there is no way to verify this.
I saw that the Changhe 4 in his hand was completely different from the flat chip on Android phones. It was more like a "cube", divided into upper and lower layers. Each layer had 3 cores, and the 6 cores were all the same size.
But you definitely can't tell from the appearance.
The outside is painted in black, and the bottom is densely packed with contacts. The difference in chip structure has the most direct impact on the motherboard design, and also has a certain impact on the internal design of the Stardust phone.
But anyone who has dismantled a Stardust mobile phone, whether it is Stardust 1 or Stardust 3+, will find that the interior of the phone is extremely clean and tidy. It is pleasing to the eye just by looking at it, and it is also convenient for maintenance personnel to replace accessories.
This time, there is not only one version of the Changhe 4. The Changhe 4 is the standard version, and there is also the Changhe 4+ with higher specifications. Certain adjustments have been made to the core frequency and will be used in models with stronger performance.
There are also special chips specially made for tablets, smart watches, drones and other products.
Haihua Chip will fully inherit Changhe 3, and use the mid- and low-end chips subdivided from Changhe 3 to continue to build mid-to-low-end smartphones, which will be used in low-end models such as Meilan and Redmi to create smart phones for everyone.
The times are working hard, and as for the mid-price models...
Mobile phone brands in this range will use Haihua chips to build a mid-range performance chip by the end of this year, which is equivalent to 80% of Changhe 3. There will also be a Changhe 3 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 configurations of Stardust 4 and Stardust 4+. There is nothing to say about the main configurations, it is just those few, but one of them is more difficult now.
Points:
How to make the difference between 4 and 4+?
Stardust 4+ is 2,000 yuan more expensive than Stardust 4, so where should the 2,000 yuan be more expensive?
In terms of imaging, it goes without saying that Stardust 4+ will continue the three-camera design of Stardust 3+ and further improve its specifications. However, Stardust 4 is not easy to mess with. It is also a very big improvement compared to Stardust 3.
After all, after two years of planning, it must have a dual camera. The fingerprint recognition that Stardust 3 does not have must be arranged in Stardust 4. However, there is no ultrasonic fingerprint, only the same under-screen optical fingerprint on Stardust 3+.
This is considered a small difference.
The ultrasonic fingerprint of Stardust 4+ is definitely more "high-end", but anyone who really knows the industry knows that the cost of optical fingerprint and ultrasonic fingerprint is not much different, and the difference in actual use is not that big.
Can you really feel it in just 0.0 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 accidental touch problems.
One thing that makes ultrasonic fingerprints really useful is that its recognition area is large enough, but not every mobile phone equipped with ultrasonic fingerprints has a large recognition area. As far as Chen Zifan knows, Meizu's is relatively small.
The biggest one should be vivo.
The fingerprint difference alone is definitely not enough. The remaining thing is the screen size. Stardust 4 is still 5.4 inches, while Stardust 4+ is 6.4 inches. The resolution is the same, but the refresh rate is operable.
The battery of Stardust 4 is relatively smaller. In order to ensure battery life (to make a difference), it will use a refresh rate of 90hz. Stardust 4+ does not have so many restrictions, and it is no problem to use a refresh rate of 120hz.
However, Stardust Technology will not be like Apple, where 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 all use high-refresh screens, and there will no longer be distinctions.
.
In terms of fast charging, the two models remain the same, both are 50W fast charging, and both are "true" full-blood versions. 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 will also be upgraded to 50W wireless charging. This time the wireless charging is also greatly improved, and the charging speed is almost doubled compared to the previous 30W wireless charging.
On the front camera, Stardust 4+ will also unlock some "new technologies". Although it has a single front camera, Stardust 4+ will have more hidden sensors.
The last thing is appearance + brand premium. Chen Zifan still remembers the original Stardust 1. It clearly used a 4.8-inch small screen, but it was called a "giant screen phone" by countless consumers. Now it seems... it can only be called a smartphone.
The development is constantly breaking the inherent concepts.
The 5.4-inch Stardust 3 has begun to be criticized by some people for its small screen. Even though it feels really good in the hand and is very compact and exquisite, it is still not enough.
If you look at Apple's mini series, you will know that every year, the popularity on the Internet is very high, but the actual sales are very dismal. Many people who have high popularity will not buy it.
Fortunately, the Stardust mobile phone does not have such a problem at present, and the mainstream mobile phone sizes are also 5 to 6 inches, so there is no problem in continuing to use 5.4 inches for Stardust 4, and it can even be used for several generations of products.
In terms of material selection for the back cover, Stardust 4 is divided into two materials: glass and plain leather, which are also the two most common and popular back cover materials. The back cover material of Stardust 4+ is stronger, similarly
The glass material of Stardust 4+ will be made towards the "jade".
It's not real jade, it's enough to make it feel like it.
The wood will still be retained, but the ebony will be replaced with another wood of the same specification. There will be a wooden back cover. The plain leather material will definitely not be used on 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 2,000 yuan will not be unacceptable. It depends on how consumers choose. If it were Chen Zifan, he would definitely choose the cheaper one.
As for the Stardust-Yaobao, as a "mass production concept phone", in addition to air charging, it will also be equipped with some brand-new technologies. After determining the specific parameters, Chen Zifan started to initiate the file.
These documents were sent to various subsidiaries as soon as possible. They would produce the required accessories according to Chen Zifan's requirements and send them to the Stardust Factory for assembly and production.
Next, you just need to wait patiently.
Regarding the remaining products, Chen Zifan has to think about it for a while. He is actually quite interested in AR glasses. After completing the work on the three new models, he contacted Zhao Wushang and asked him to find a few professionals.
Cooperate with suppliers responsible for lens production.
Why not look for glasses brands…
At present, few domestic eyewear brands have their own technology, and the profits of lenses are very high. Some unscrupulous brands can even achieve an overall profit margin of more than 200%. You can imagine how exaggerated it is.
The reason for cooperating with lens suppliers is to save time and expand new business for Stardust Technology. The reason is also very simple. Based on the current domestic situation, more and more consumers will wear glasses.
Chen Zifan has read the survey report of Haicheng in 2012. The glasses rate in primary schools is 28.7%, the glasses rate in junior high schools is 39.6%, and the rate in high schools has exceeded 50%, reaching an exaggerated 52.4%. Moreover, myopia is theoretically irreversible.
It can't be taken off.
But then there was laser surgery...
However, Chen Zifan has always had reservations about vision correction surgery. Since the proportion of people wearing glasses has increased significantly, AR glasses cannot be sold only to consumers who do not wear glasses. They must cater to mass consumers and be specially produced for myopia groups.
version.
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 thing. 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 Chen Zifan has learned, after [Stardust Technology] reaches lv.80, higher-level [Stardust Blueprints] can be unlocked. The blueprints also include some key technologies in construction and power generation.
The second is the [Analysis of Copycat] and [Synthetic Creation] of materials. This is a brand new breakthrough. [Stardust Technology] has been able to only analyze and "electricity" or products derived from "electricity" before.
Such as operating system, etc.
But it's a bit difficult to analyze stone and steel. Of course, these basic materials are not important. What Chen Zifan lacks is various high-end materials. He needs to use the materials in cars, mobile phones and other products.
Even mobile phones, tablets, and future laptops will need some new materials for heat dissipation, which can not only be used as gimmicks, but also enhance product capabilities.
During this period of waiting, the influence of the Stardust press conference has reached a new level due to the fermentation of public opinion. From Stardust-Chenji to Xinghan 001, the enthusiasm of countless consumers has been ignited, and there are also a large number of Stardust
Users go to the local Stardust after-sales center.
It's not that their mobile phones are broken, but they heard that Stardust mobile phones can be replaced with new sodium-lithium batteries for free. The capacity and battery life are significantly improved, and the charging speed is also faster. They all want to pick up the wool.
The role of the Stardust After-sales Center is reflected. It is not only used to repair mobile phones. Various after-sales problems can be solved here, such as receiving mobile phone cases at a fixed time every month.
Another example is free stickers and so on.
Stardust Technology's curved screen cannot be installed by ordinary people, so it is better to let the after-sales staff operate it.
Chen Zifan spent so much money to cover the nationwide after-sales service and played a huge role. Many Stardust users who bought mobile phones online also experienced for the first time what the offline services of the Stardust after-sales center are like.
