Chapter 192: Impacting 1Ghz
Fang Ziming is worried, Boss Qiu is an investor, and he can't help it, he originally hoped to ask Mr. Wang to come over and neutralize it, but Mr. Wang didn't give face, what to do, there is no solution.
But when Qiu Baijun stretched out his tentacles to the international version of dubbing, Fang Ziming realized that it was time to meet with another big boss......
......
The conscience of heaven and earth, Wang Anran is not without face, he is really busy now.
The graphics card division, the CPU division, chip production, FinFET structure and mathematical models are all things he has to worry about, if he doesn't step down as the CEO of the three major companies, I'm afraid he will be even busier.
Even so, Wang Anran hadn't slept a good night's sleep for a long time.
Today, he came to the CPU Division, thanks to the good planning of Huaxin Technology, a complete set of R&D planning in the current product and its optimization, future product research and development, and future product demonstration.
In the face of Intel's aggressiveness, the CPU division did not show panic and developed in an orderly manner.
The only difference is that 800 nanometers, 500 nanometers, and 180 nanometers for 40 million transistors, the three manufacturing processes go hand in hand.
The 800nm Athlon-generation Pro model has begun mass production, and it was almost released, and the benchmark is the Intel Pentium 586 third-generation processor, and the results of the tape-out test are in line with the tone, complete, and the performance parameters are the highest, nearly 27% higher.
The 500-nanometer manufacturing process is the benchmark Intel Pentium II processor, and in Wang Anran's impression, this processor is about to be born.
As for the processor of the 180nm manufacturing process, it uses the 180nm manufacturing process that Texas Instruments is debugging.
According to the project cost calculation, after mass production, the cost of each qualified processor will be as high as more than 3,000 US dollars, which is equivalent to more than 20,000 yuan.
The market facing is naturally high-performance computing centers, as well as local tyrant players with mines at home.
For Wang Anran, high performance is not enough, and on this processor, he has to break a world record, which is to hit the 1Ghz frequency mark.
There are two ways, one is to continue to explore the potential of the assembly line and deepen the existing pipeline from level 18 to level 32.
Another approach is to use a reduced instruction set as much as possible to reduce the delay caused by a complex instruction set under non-essential conditions.
At the product demonstration meeting, Wang Anran put forward several key points.
"The 180nm manufacturing process is provided by Texas Instruments, which is an opportunity to demonstrate Huaxin Technology's super technical strength in the field of CPU design, and an opportunity for us to officially stand on the same weight as Intel and surpass it......"
Wang Anran doesn't know how to stir people's hearts, he just reveals his true feelings, and has been silent in the shadow of Intel for too long, now the time and place are favorable, to design and design, to manufacture and manufacture, and there are advantages that Intel does not have, that is, Texas Instruments 180nm manufacturing process, which Intel has not yet mastered.
The audience was excited, Wang Anran saw it in his eyes, and continued: "Today is a product demonstration meeting, I will mention a few indicators, let's discuss them together." ”
After Wang Anran finished speaking, the underground technicians opened their notebooks one after another to record.
Historical experience proves that Mr. Wang never talks nonsense at the product demonstration meeting, and strangely enough, most of the opinions he says are the core technology of new products.
Sure enough, Mr. Wang's first sentence made them pick up the big material.
"This time, we will hit the frequency of 1Ghz ......"
The scene was silent, and they looked at Wang Anran with wide eyes one by one.
Gu Liang, the new technical director, was the first to ask: "Mr. Wang, the CPU frequency is 1Ghz, so how much is the front-end bus frequency, how much is the frequency doubling design, the current existing North Bridge chip, PCI bus, memory and other buses may not be able to keep up with the speed of the processor, which will form a huge bottleneck, can not play the performance of the processor." ”
"Good, that's a good question. ”
Before the Pentium, the front-side bus was equivalent to the CPU frequency, and after the Pentium, the CPU frequency increased much faster than the speed of the front-side bus, which introduced the concept of frequency doubling.
As for the 1Ghz CPU frequency proposed by Wang Anran, insiders quickly realized that the bus frequency must be greatly increased in order to exchange a large amount of data with the Beiqiao chip and give full play to the performance of the CPU.
This question is easy to explain, assuming that the Ryzen 3900 processor you use is not equipped with DDR 4th generation 3200 memory, but the first generation DDR400 memory, and the performance loss is at least 80%.
The reason is simple, the data exchange does not meet the computing needs of the processor, that is, the processor is simply not fed.
However, after the front-side bus frequency increases, the corresponding PCI composition cannot keep up, so the bottleneck always exists.
Wang Anran took a sip of water, obviously, inertial thinking, the fsb front-end bus and PCI bus have always been the same frequency, but in fact, there is no need to wait for the equipment bus at all, if you can run fast, you will naturally run faster.
This involves memory technology, the front-side bus is closely linked to memory, for example, in the four years of Pentium, the Northwood core processor, the 800mhz fsb front-side bus and the dual-channel DDR400 are completely cohesive, and the PCI bus interface at this time is only 133mhz.
As always, although Wang Anran knew the standard answer, he was reluctant to say it directly, otherwise his engineers would have less fun, after all, not everyone likes spoilers.
Wang Anran looked at Gu Liang and said, "Director Gu, what do you think?"
"The CPU frequency is increased to 1Ghz, according to previous estimates, the front-side bus must be increased to a frequency of 400mhz, and the memory is now 166Mhz, after upgrading to the 180nm manufacturing process, the gap is not too big, but the equipment bus is synchronously improved, which requires the progress of the entire industry. ”
Wang Anran took a sip of water and said casually: "If the industry does not progress, shouldn't our CPU develop?"
Wang Anran's words were a bit heavy, and Gu Liang scratched his hair a little embarrassed.
As a technical director, you should understand that what the team needs to do is to solve the problem, rather than being led by the nose.
This point is to be hammered.
"The CPU frequency is higher than the front-side bus, why should the front-side bus be the same as the device interface frequency? ”
Under the explicit hint, someone finally thought about this problem.
Yu Xiaotao, a senior engineer, said: "Mr. Wang, we can try to introduce QDA frequency doubling technology between the front-side bus and the device interface. ”
Once a layer of window paper is pierced, it is not interesting.
Wang Anran nodded and said: "QDA frequency doubling technology is just a technical measure, adjusting the relationship between the CPU frequency and the front-side bus and the frequency of the device interface, we have to do more than that. ”
