Lu Wei was very sad, he could swear that accepting Wang Anran as a student was completely out of love, he was a vice president of Qing University, how could he be a scheming person in the eyes of Su Lao?

But he is also very helpless, the more he shines as a student, the more Lu Wei feels like being roasted on a fire, what he thinks about most now is how to graduate this demon and draw a clear relationship from now on.

Otherwise, people will always say:

"Wow, this kid is so good, who is his teacher!"

"It's Lu Wei's bastard, the master can't catch up with the apprentice. ”

Thinking about Lu Wei, it is also heartbroken, thinking that we were also the pride of the sky back then, well, the three proud protégés of Su Laomen, we are ranked first.

Forget it, the hero didn't mention the courage of the year, Lu Wei shook his head and walked out of the glass door of the Huaxin Technology Building......

…………

Wang Anran was staring nervously at the display screen, nervously looking at the flashing test data, and found that one bug was worth $300,000 and two were worth $600,000......

And it's not just about money, it's about time.

There are two most important chips on the graphics card, and the first one is naturally the GPU chip, which is the core of the graphics card, and its performance determines the performance of the graphics card.

Second, it is naturally the video memory chip, compared with the current general-purpose EDO DRAM memory on the microcomputer, the bandwidth is only 32bit, and the speed is 33Mhz, which is far from keeping up with the speed of the graphics card chip 133Mhz, which causes a point, that is, the processing efficiency of the GPU will be far dragged down by the video memory.

Of course, there is another important point, that is, the price of EDO DRAM memory particles is expensive, 1m capacity memory particles cost more than 30 dollars, and their flagship graphics card is equipped with 32M video memory, and the cost of video memory alone will cost 1000 US dollars, such a price is obviously unacceptable.

Wang Anran's solution is to redesign a set of memory standards, compared with the standard battle in the compatible microcomputer, inside the graphics card, it is an independent closed loop, as long as the interface of the graphics card meets the interface standards of the compatible machine, as for how to implement it internally, there is no standard constraint.

In this way, Wang Anran can move the mature DDR memory standard of 9102 to the graphics card without any worries.

The DDR standard is derived from the classic generation of SDRAM memory, and the memory specification standard used is based on the SDRAM memory standard, and uses bidirectional data transmission on the rising and falling edges of the clock signal.

This allows DDR to transfer twice as fast data as its predecessor, classic SDRAM memory, without increasing the frequency without causing an increase in energy consumption.

Of course, as a compromise between performance and cost, the cost of DDR memory solution is much lower than that of EDO DRAM memory.

Limited by the current 1 micron manufacturing process, the DDR memory particles designed by Wang Anran did not dare to make a big leap, but the capacity is still double the maximum capacity of the existing EDO DRAM memory particles, with a single 2M and a frequency of 133Mhz.

DDR memory chip is a product that Wang Anran has high hopes for, because the patent of DDR memory itself contains the patent of SDRAM memory, plus the DDR series is a sustainable storage standard, and there are DDR second generation, DDR third generation, and DDR fourth generation in the future......

This is equivalent to making it clear to the major giants in the field of compatible machines: if you want to take the road of SDRAM and DDR, you have to pay for the road.

It would be better if you exchanged some patents with other giants.

Of course, it is also possible that the other party designs other memory structures to bypass DDR and sdram standards, but since DDR has come to the present, it can also be said that this is an extremely excellent product.

The test lasted until nine o'clock in the evening, and halfway through, all the staff of the graphics card division had a simple working meal, but the results were obvious, Wang Anran and his team twitched with the test data one by one, and still found a few hidden bugs.

After the end of the test, Wang Anran announced: countdown for a week, everyone, found a bug or defect, the company will reward 50,000 yuan.

"Wow!"

There was a cheer at the scene, 50,000 yuan, for most people, it is equivalent to more than a year's salary, all I have to do is to check the data in front of the computer, and if I come across one, I will win the jackpot......

…………

Eggs can't be put in one basket, this Wang Anran naturally has a clear understanding, so when choosing a foundry, he is not just staring at TSMC.

Wang Anran set a goal for the shipment of GPU graphics cards, that is, 200,000 pieces, and he sent 80% of the demand for GPU chips and 20% of the demand for DDR memory chips to TSMC, and outsourced the rest of the demand to Samsung for production.

As for Toshiba and Micron of the United States, they are not considered for the time being.

Of course, this ratio is also dynamic, depending on the situation, but then, Wang Anran is worried again, although it can be divided into batches, but the entire foundry cost, where does the foreign exchange of tens of millions of dollars come from?

In 1994, the state launched a large ethylene production line, a petrochemical production line, and a large steel and special steel production equipment...... Coupled with the introduction of various scientific research equipment, their own foreign exchange is not enough, can they apply for it?

The answer is yes!

Zhang Changyong, the chief financial officer, went to the State Bank of China, negotiated the foreign exchange matter, and set aside an exchange quota of 10 million US dollars, and the exchange rate was fixed at a fixed exchange rate of 100 US dollars and 855.91 yuan.

"Mr. Wang, as far as I know, 855.91 is already the lowest exchange rate for the whole year, and the bank also promised to refund me the difference when the floating interest rate is lower than 855.91.

I've been in finance for so many years, and it's the first time I've encountered something like this. ”

Wang Anran pointed to the ceiling with his finger and said to Zhang Changyong: "This matter is like this, don't make a noise." You go back and prepare, exchange $2 million in advance, find a bank that is convenient for depositing and lending in Wanwan, open a corporate account, and deposit the money. ”

Zhang Changyong walked out of the office, Wang Anran returned to the desk, picked up the teacup, and took a sip of water.

Now everything is in place, only the east wind is owed.

This time, Wang Anran needs to go to Wanwan in person, not only because of TSMC foundry matters, but also because the release of graphics cards also needs allies, Wang Anran set his sights on ASUS Technology.

ASUS Technology is a motherboard manufacturer, founded in 1989, although it was not expected that ASUS would grow into the world's largest motherboard manufacturer in just a few years.

In 1992, ASUS motherboards shipped more than 30,000 units per month, and then they were like wild horses, enjoying high praise in the world board field.

What Wang Anran wants to do is to pull ASUS into the Fissioner Alliance, and with its influence in the world, the difficulty of releasing graphics cards will be greatly reduced.

At the same time, it is also necessary to inspect the chip manufacturing level of Wanwan on the spot, and if possible, buy two second-hand chip production lines, although they are definitely outdated, but they are still very useful for training.
