Chapter 287 The research and development of the -yuan mobile phone is completed

Fortunately, the students who can get into Peking University are all the proud ones and have a lot of arrogance. Very few of them come over and take the initiative to strike up a conversation. On the other hand, some female classmates looked at Qiao Ruida with particularly hot eyes. If Du Qingqing wasn't by her side, they would have taken the initiative and asked for autographs, photos, phone numbers, etc.

In recent days, Qiao Ruida has received many invitations, including interviews from magazines and newspapers, interviews from TV stations, and memberships from entrepreneur clubs. There was even an invitation letter from the China Internet Conference, which clearly stated that he was one of the guests of honor and could speak on stage. Most of these invitations were turned down by Qiao Ruida. Studying, researching, and managing the company had taken up most of his time, and he had no time to waste on these meaningless entertainments.

However, there are still some invitations that are difficult to refuse, such as the invitation from the CCTV dialogue column team and the invitation for an exclusive interview from the Youth Daily. These require Qiao Ruida to spare time to complete. There is also the China Internet Conference to be held in the middle of this month. Qiao Ruida is also interested in it and plans to spare some time to attend.

On this day, Qiao Ruida drove to the Ruida Technology R&D Building to learn about the trial production of the Roadster sports car. Xiao Jingsheng, manager of the R&D department, brought him good news. The 100-yuan smart phone project that was established a few months ago has completed research and development and preliminary testing, and is just waiting to be finalized and mass-produced. After hearing the news, Qiao Ruida didn't even bother to look at the newly produced Roadster test prototype, and went directly to the mobile phone R&D team with Xiao Jamsheng to check out the newly released 100-yuan smartphone.

"Mr. Qiao is here!" "Good morning, Mr. Qiao!" Seeing Qiao Ruida, who had not shown up in the R&D department for some time, reappearing, the researchers stopped what they were doing and greeted him.

"Hello, you guys, you have told me so many times that you don't need to call me out, just do whatever you need to do. Where is the 100-yuan smart phone you developed? Bring one over and let me test it." Qiao Ruida waved her hand, indicating that everyone is welcome. .

"The test mobile phones are here. We have assembled hundreds of them in total and handed them over to the mobile phone R&D team and testing team for daily use and extreme environment testing." Xiao Jingsheng found a desk in a familiar manner and opened the top A drawer took out a white mobile phone and handed it to Qiao Ruida.

Qiao Ruida took the phone, held it in her hand, and began to check the appearance of the phone. In order to save costs, this new mobile phone does not use the full screen, glass back cover, and metal middle frame used on the second-generation mobile phone of Reda. The screen uses an ordinary 5.5-inch IPS screen with a resolution of 1920x1080 pixels and a maximum brightness of only 300 nits. The viewing effect is not very good under sunlight. There are also traditional wide foreheads and big chins on the upper and lower sides of the screen, which makes Qiao Ruida, who is used to seeing full-screen mobile phones, quite uncomfortable. The middle frame and back cover of the phone are made of one-piece plastic material. No matter which color you choose, it looks cheap.

There is only one front and rear camera. The front camera only has 500 million pixels with f/2.4 aperture. The rear camera is better, with 1600 million pixels, f/1.8 aperture, and no optical image stabilization. With this parameter configuration, if you want to get a good performance It's impossible to use it as a film. It's not a problem to use it for daily photography and scanning QR codes. Just the main one is enough.

Qiao Ruida pressed the power button and the screen quickly lit up. After a familiar cutscene, she successfully entered the system desktop. Sliding up and down, sliding left and right, is smooth and silky, and there is no obvious lag when opening and closing the software. There is no problem connecting to the WIFI network, browsing the web, and watching videos. Even playing some pre-installed games can still remain smooth. But when Qiao Ruida opened this year's more popular mobile games "Tiantian Cool Run", "Temple Run 2" and "National Shootout 2", this cheap yuan machine finally couldn't bear it, and its true colors were exposed. The game screen was stuck, frames were dropped, and the machine was not playing well. My body was very hot and I was basically in a state where I couldn't play.

Qiao Ruida closed the game, returned to the desktop, opened the settings options, and checked the configuration information of the phone. The ROM version column is the same as the second-generation Ruida mobile phone, with only the version number and no operating system name. The processor is Kyushu 425, the memory is 4G, and the storage is 32G. The communication standard supports 3G full Netcom and 4G full Netcom, which is one of the few highlights of this phone.

Qiao Ruida asked: "Is the Jiuzhou 425 chip used in this mobile phone obtained from the shielding core of the Jiuzhou No. defective chip, or did you redesign it for tape-out?"

Xiao Jingsheng said with great certainty: "Of course it is a redesign of the tape-out. You don't know that Rockchip Wafer Factory has increased the yield rate of 28nm chips to more than 90%. I want to find a Jiuzhou No. 425 It is simply too difficult to produce defective chips. The Jiuzhou 60 chip we redesigned is a native quad-core with a simpler structure, fewer transistors, smaller chip area, and more power saving. It has a large Core, one medium core, and two energy-efficiency cores, the CPU performance is only half that of the Jiuzhou No. chip. The number of GPU cores has also been cut in half, and the display performance is only about % of the Jiuzhou No. chip. However, it is used for daily playback of high-definition videos and games. Some small games are enough.”

The Ritar MINI tablet computer released a few months ago was equipped with a Kyushu 425 processor. That processor was obtained by shielding some cores based on the Kyushu No. 425 processor. Now this hundred-yuan smartphone is also equipped with the Kyushu processor, but it is a redesigned native quad-core model. It will definitely perform better in terms of power saving and stability.

"What about the baseband chip? Does it still use Qualcomm's baseband?" Qiao Ruida continued to ask.

"No more. For the first time, this 4-yuan phone is equipped with the G full network baseband chip developed by our Reda Technology. After testing, its signal performance is no worse than Qualcomm's latest baseband chip. It's just that after turning on data traffic, it consumes more power. The quantity is a bit large, and it is not as power-saving as Qualcomm's baseband chip." Speaking of baseband chips, it just scratched Jamel Xiao's itch, and the introduction was particularly laborious.

Qiao Ruida operated the phone, turned on the traffic switch, turned off the WIFI switch, and then tested the main usage scenarios of browsing the web, watching live broadcasts, chatting, and watching videos. The phone was still clear and smooth, and there was no lag when playing online games. connection situation. When using the 3G data network, the power consumption is indeed a bit high, and the phone body heats up significantly. The planned 4G mobile communication network has not been implemented yet and cannot be tested for the time being.
