Jiao Bai nodded and agreed: "It makes sense, from today onwards, everyone must be careful of strangers around you, if it is not necessary, try not to go out alone, I will also arrange more security personnel to protect everyone's safety." In addition, it is necessary for us in the Star Group to set up a special intelligence department to collect information on our opponents. Just like the current Order Society, we still know too little about it. ”

After the meeting, Jiao Bai followed Lu Anguo to the Xingchen Research Institute, yesterday the first batch of CPUs for SMIC's tape-out trial production has been packaged and sent to the Xingchen Research Institute for testing, Jiao Bai came to see the test results.

The CPU designed by the Star Research Institute makes use of the mature architecture of the end of the world, and only fine-tunes some details to adapt to the peripheral components and related communication protocols on the earth's side, and the chance of success is still relatively large. Jiao Bai is worried about the compatibility of the chip production process and design drawings on this side of the earth, after all, the original architecture is a product with a 3nm process, and now it is produced with SMIC's 14nm process.

Walking into the integrated circuit testing laboratory, more than a dozen researchers were busy with their work, and when they saw Jiao Bai and Lu Anguo coming in, they just nodded and continued the work at hand.

The person in charge of this laboratory is Shang Hongbo, who was personally recruited by Jiao Bai at the on-campus job fair of Wanghai University, and his main direction is CPU design. It may not be enough to let him design a new CPU independently, but it is still okay to just test the performance of the good CPU.

Seeing Jiao Bai and Lu Anguo coming, Shang Hongbo greeted him, held Jiao Bai's hand, and after greeting him, he sighed: "Only now do I feel that working in Xingchen Company is the wisest decision I have made in the past few decades. In the two months I worked at the graduate school, I learned more new things than I learned in several years at school. ”

Jiao Bai showed a smile and said in his heart, "It's right that you feel this way, a new world's knowledge system is enough for you to learn for decades." ”

After chatting a few words, he finally turned back to the topic, and Jiao Bai asked, "Dr. Shang, how is the CPU testing going?" ”

Shang Hongbo took a folder from the desk behind him, handed it to Jiao Bai, and said: "The test work has been completed, the data is quite perfect, and the performance has comprehensively surpassed Intel's eighth-generation i7 This is the test report." We were going to test the CPU on a build, and because the architecture and package specifications were different, we redesigned the motherboard, and now these colleagues of mine are working on the board for testing, which should be done soon. ”

Jiao Bai nodded, took the report and looked at it, in fact, as a software programmer, Jiao Bai had a very limited understanding of various parameters in computer hardware, and there was not much information that could be understood. Fortunately, Shang Hongbo is intimate enough, and the test results of the same items of Intel i7, Zhiqiang E5 and Zhiqiang E7 CPUs are attached to each data for comparison. With these comparative references, as long as there is some basic common sense, it can be seen that Xingchen's self-developed CPU comprehensively crushes Yingerte's i7CPU in terms of performance, and the performance is close to that of Zhiqiang E5CPU.

You must know that Zhiqiang E5, as Intel's server-level flagship CPU model, has a market price of more than 4,000, and the CPU handed over by Xingchen to SMIC will not exceed 600 yuan. If it is mass-produced, it can even reduce the cost to less than 300 yuan. A price difference of more than ten times means a profit margin of more than ten times, which makes people crazy when they think about it. Moreover, Zhiqiang E5 is a processor with twelve cores and twenty-four threads, while Xingchen's self-developed CPU is just two cores and two threads, and there is still a lot of room for development. As long as the technology matures in the future, integrating a few more cores is just a matter of changing the design drawing.

Ten minutes later, a young man took out a dozen dozen rushed circuit boards from the PCB automatic plate making machine, and after corrosion, they were directly handed over to Shang Hongbo. Due to the rush of time, the circuit board has not been sprayed with tin, spraying insulating paint and other processes, and directly showing the brownish-yellow color of the fiber substrate itself, which is densely covered with lines formed by yellow copper foil of different thicknesses. They didn't take the circuit board to the factory to solder it with a machine, Shang Hongbo and these people took out a circuit board for each person, and then took out a bunch of capacitors and resistors and other components, and directly soldered them by hand.

Jiao Bai and Lu Anguo also found a vacant seat and sat down, patiently waiting for them to weld. About half an hour later, Shang Hongbo's soldered circuit board was the first to be completed, and after testing it with a multimeter, he repaired a few solder joints that were not soldered. After testing again, Shang Hongbo connected the power supply, switches, displays and other external devices to this circuit board, and wrote the hardware boot program that had been prepared long ago to the BIOS chip. When all was done, he pressed the start button, the power indicator lit up, and the radiator fan began to spin. A few seconds later, the buzzer made a soft "tick-" sound, and the self-test passed, which means that the soldering of this motherboard is fine, and the CPU used for the test is completely normal.

Shang Hongbo waved his hand vigorously and said excitedly: "yes, it's successful!" ”

Several other researchers have also completed the motherboard soldering, but they are not skilled technicians in the electronics factory after all, and the welding technology is not complimentary, the solder joints are rough and sticky, and even the components are inserted in a mess, which is not beautiful and neat at all. In the end, there were only three pieces that could pass the self-test, the one connected to Shang Hongbo.

Completing the self-test is not a final success, it just shows that the hardware is fine. If you want to enter the system and log in to the virtual game, you also need to replace the driver originally designed for Intel CPUs to adapt to the new CPU. This work must be completed by professional hardware engineers, and Shang Hongbo is still far from it. Fortunately, there has never been a shortage of technical experts in all aspects of the Xingchen Research Institute, Shang Hongbo personally went to the supercomputing and quantum computer research group to invite Ye Le over to help complete the writing of the driver.

Ye Le is one of the fourth-level zombies summoned by Jiao Bai with crystals after upgrading to level four, mastering grandmaster-level brain science (brainwave deciphering direction) skills, advanced integrated circuit design skills, master-level quantum computer design skills, and advanced human memory optimization skills, and is an authority on virtual glasses in the Star Research Institute.

After Ye Le came to the laboratory, after greeting Jiao Bai and Lu Anguo, he didn't talk much nonsense, and went directly to work.
