Chapter 69: H10
In Yu Dazui's view, the difficulty of designing a processor chip is still relatively huge.
After all, HiSilicon Kirin designed and produced processor chips, and it took more than ten years of hard work to get to where it is today.
The semiconductor company behind Zhou Zhen has only been established for a long time, and now it is starting to enter the design of mobile phone processor chips, which is a little too impatient to be honest.
However, the help should still be helped, Zhou Zhen is now cooperating very closely with the chrysanthemum factory, and Yu Dazui is still willing to help with some small things.
As for whether it will succeed in the end, these are not the focus of Yu Dazui's attention.
With the introduction of Ju Factory, Liu Wei, the person in charge of Yuzhen Semiconductor Co., Ltd., finally contacted ARM.
After several rounds of negotiations between the two parties, Rouyu finally spent 80 million yuan to obtain a three-year license to use and modify the A76 and A55 architectures.
Zhenyu can also officially start to enter the field of mobile phone processor chip design.
"This time, the name of the company's chip project is called Tianxuan, and the processor CPU core plans to use the 1+3+4 architecture to design the chip!"
After obtaining the authorization of the relevant core technology, the company began the design of mobile phone processor chips.
As a processor chip with excellent performance and power consumption, A76 adopts a 1+3+4 core architecture that is very reasonable.
Of course, the design of the super-large box is chosen in the processor chip design, so in terms of the processor chip production process, the first consideration is the production of the most advanced 7nm EUV process.
After all, when using a super-core design, the heat generation and power consumption of extreme performance are the areas that designers need to pay attention to.
Only by using the latest and best nanofabrication process can the processor chip ensure the corresponding temperature and power consumption at high frequencies.
And Zhou Zhen looked at TSMC.
TSMC, as the world's best and strongest chip foundry, has a reputation in the industry that is obvious to all.
Now the mainstream chip manufacturing process is basically ten nanometers, but there is a grapevine that TSMC has been able to mass-produce processor chips made of seven nanometers.
In the second half of 18 years, TSMC's seven-nanometer process will gradually become popular.
And from the end of 18 to 20 years, these two and a half years will fall into a period of stagnation of the "seven nanometers" process technology.
Although TSMC has claimed several times that it has made corresponding technological breakthroughs in the seven-nanometer process, the actual upgrade is not very large.
The processor chip designed by Zhou Zhen is a chip designed using 7nm process technology.
Of course, the current Zhou Zhen did not think about designing and producing the chip immediately.
After all, according to the current R&D strength and manpower of our own company, it will take at least nearly a year to completely design the chip.
After an appropriate amount of tape-out, mass production can be carried out.
From design to production to selling to other mobile phone manufacturers, this period will take at least nearly two years.
This also means that Zhenyu wants to design, produce and sell processor chips, and that is until the end of 19.
The end of 19 is basically the arrival of 5G chips, and the processor chip designed by Zhenyu Company should also take into account the baseband problem of 5G in the final design.
Built-in baseband? It is estimated that Zhenyu does not have this technology now.
External basebands may be available from the corresponding technology companies.
Plug-in domestic 5G mid-to-high-end chips!
This time, Zhou Zhen plans to design two chips.
One is benchmarked against the Dimensity 1000 and Fire Dragon 855+, which were released in the second half of '19.
The other is the benchmark for the Fire Dragon 765G and Dimensity 800 processor chips released at the end of the year.
After all, if this chip is launched at the end of 19, then the target chip is basically a 20-year-old chip.
In the 20-year mobile phone market, one of these two chips will act as a sub-flagship processor chip, and the other will act as a mid-range processor chip.
To this end, at the project meeting, Zhou Zhen also made corresponding plans for chip design.
Among them, the 20-year-old Tianxuan sub-flagship chip, A76 super large core can not be lower than 2.75Ghz, three A76 medium cores cannot be lower than 2.4Ghz, and four A55 cores cannot be lower than 2.0Ghz.
After all, the performance of this processor chip is basically comparable to that of the Fire Dragon 855+ and Kirin 990, which also use the A76.
The Fire Dragon 855+ uses the main core to reach 2.96Ghz, the middle core to reach 2.4Ghz, and the small core to reach 1.8Ghz.
The Kirin 990 adopts a "2+2+4" design.
Two 2.86Ghz A76 cores are paired with two 2.1Ghz A76 mid cores and four 1.8Ghz A55 cores.
It can be said that in order to make the processor chip comparable to the two processor chips in the CPU performance, Zhou Zhen must increase the core frequency of the processor CPU designed this time.
Only in this way can the CPU performance of the processor be on par with that of competitors.
The other processor chip for the mid-range is relatively just downclocking.
Even after discussing the design of this chip. A 2+2+4 core design architecture will be adopted.
The frequency of the two large cores is not less than 2.6Ghz, the frequency of the other two medium cores is not less than 2.1Ghz, and the frequency of the other four small cores is not less than 1.8Ghz.
It can be said that the overall design of the mid-range chip this time, if it is placed this year, is definitely a flagship-level processor series.
It's just that the current Yuzhen company can't complete the design and production of chips within a year.
So I can only temporarily focus on the mobile phone market two years later.
In addition to the CPU, in this meeting, Zhou Zhen came up with a new set of GPU core solutions.
The core architecture of this new GPU is a reward for the tech tree.
This also means that the GPU of these two processor chips will use the GPU core architecture independently developed by Yuzhen.
The name of this new GPU core is called H10 core.
It is a GPU core architecture with excellent compatibility and performance and power consumption.
This core architecture is 67% stronger than the G76 core of the ARM public version at the same frequency, 32% stronger than the G77 that has not yet been released, and 23% stronger than the G78.
And at the same frequency, the theoretical power consumption of the H10 core is 25% lower than that of G76, 15% lower than that of G77, and about 5% lower than that of G78.
This means that in the case of theoretical energy consumption ratio, H10 is 122% higher than G76 core, 55% higher than G77, and 29% higher energy consumption than G78.
The G76 core is used in the future Kirin 980 and 990.
The G77 is used in the Dimensity 1000 series.
The G78 is used in the Kirin 9000 product.
This also means that the core of H10 is very strong, and it can be regarded as the top existence in the industry in 2020.
In order to make the processor chip designed by this company have the core competitiveness, this time Zhou Zhen took out the core architecture of the GPU of H10 directly.
This core architecture can be said to be a big killer among chip design manufacturers.
In related discussions, it is planned to use the sub-flagship processor chip with an 18-core GPU design.
This will make the GPU performance of this processor comparable to that of the Kirin 9000's 24-core G78 processor chip.
The mid-range processor chip is designed with a 12-core GPU, and the overall performance is basically at least 20% stronger than the Kirin 990's 16-core G76 graphics processor.
In general, the processor chip designed by Yuzhen will become a major selling point of this series of processor chips in the future.
