Technological power starts with upgrading lenses

"Kacha kacha kacha——"

After returning home, Kang Chi first took out his camera and took a few shots at his home to test the focusing performance of the third-generation lens.

The result is obvious,

The system upgrade thing is really delicious!

The focus speed for taking photos is fast and ruthless, and the focus for videos is also very smooth.

Even in a relatively dark environment, there is no bellows phenomenon.

The only regret is that the picture quality seems not to have improved much.

It seems that with this upgrade, the skill has improved all-point autofocus...

Kang Chi put the lens away with satisfaction.

It's not time for it to come out yet.

After putting away the lens, Kangchi took out the graphics card again and upgraded it again.

After this upgrade, the manufacturing process of this graphics card has reached 28 nanometers, and the core graphics and video memory have also been upgraded to 980MHz and DDR5 4GB respectively.

Although the parameters have been greatly improved, Kangchi still feels that it is not enough.

In this era when mainstream graphics cards are already 8nm, 1.5GHz clocked, and 12GB of video memory,

This graphics card has performance comparable to that of the Invida GTX7 series. Even if it focuses on cost-effectiveness, it probably won't have a big market.

So you still have to continue to upgrade.

But seeing the 1,600 points of upgrade experience, everyone in Kangchi became numb.

Where did he get so much general experience?

Therefore, using universal experience is definitely not feasible.

I can only think of a way to directly add experience to this card.

So Kangchi directly plugged this graphics card into his computer host and tried to install an Invida driver.

The result is that it cannot be recognized at all.

There was no choice but to go to Wang Haowen.

Kang Chi took out his mobile phone, bought a train ticket to Lin'an the next day, and went directly to wash up and go to bed.

Early the next morning, because it was rush hour, Kang Chi stood on the roadside and waved for a long time before finally getting an empty car and almost missed the bus.

In fact, Dongyang is not far from Lin'an, it only takes more than two hours by car.

But it took Kang Chi more than five hours from going to the station to taking the train, and then taking a taxi to Jiangsu University.

Not only is it inconvenient, it’s also tiring.

This made Kangchi immediately want to buy a car.

After buying the ticket yesterday, Kang Chi and Wang Haowen made an appointment in advance on the phone to meet at a meeting place.

When Kang Chi walked into this coffee shop with a unique environment, he quickly saw Wang Haowen who was reading a book.

He immediately walked over and patted the table gently: "Brother Wang, long time no see."

Wang Haowen raised his head, glanced at Kang Chi, and said with a faint smile: "How long? It just happened a few days ago... To be honest, I didn't expect that we would meet again so soon."

"Don't want to see me?"

"That's not true." Wang Haowen shook his head, "I'm just a little curious."

Although this young man who was slightly younger than him gave him the first impression of being ignorant of the heights of the world,

But after actually getting along with him, he found that Kang Chi was actually quite humble and didn't mince words when he spoke.

Especially when he realizes a mistake, he will admit it without hesitation.

So after he went back that day, he checked Kangchi and Longteng Technology. The structure unexpectedly discovered that he was not simple at all.

He was able to make a camera lens and fought with Soni and won a great victory.

Even Wang Haowen felt envious after seeing this record.

After Kang Chi sat down, he ordered a cup of coffee from the waiter, and then without saying a word, pushed a black box in front of Wang Haowen.

"This is it?" Wang Haowen glanced at Kang Chi in confusion.

Kang Chi smiled pretending to be mysterious: "You'll know when you open it and take a look."

So Wang Haowen carefully opened the lid, and what he saw was a black single-fan graphics card without any LOGO on it.

Although Kang Chi didn't say anything just now, Wang Haowen vaguely guessed something.

So when I saw this graphics card, I immediately opened my mouth slightly in surprise.

"Did you do this at Liu Yu's place?"

"How can it be."

Kang Chi forced out a complicated expression, "You may not have any idea if you haven't seen his factory. They are all old equipment from decades ago. It's a miracle that they can still produce."

"Then what is this? Did you find the parts and assemble it yourself?"

"Sorry, this is a trade secret."

"All right."

Wang Haowen shrugged, then picked up the graphics card and looked at it carefully.

But after reading it, his curiosity became even more intense.

Even if there is no obvious logo on the graphics card, all the parts inside do not have any markings either.

Not even a single number or letter can be found on the small capacitor.

But he couldn't see any traces of being wiped.

This is very strange.

"28nm process, 980MHz main frequency, 4GB DDR5 video memory."

During Wang Haowen's observation, Kang Chi also stated its parameters.

"28 nanometers?!"

Wang Haowen was even more surprised when he heard the parameters.

You must know that in their laboratory, without using Eagle Sauce equipment, they can only achieve 28 nanometers at most.

And the yield rate is not high.

"Is this for SMIC?"

"Trade secrets."

"..."

Wang Haowen was almost choked with cataracts by these commercial secrets!

He put the graphics card back into the box, leaned back with his hands on his chest, and said, "Let's be honest, what do you want to do?"

"Didn't I tell you last time? Are you interested in doing a part-time job?"

"Make a driver for this graphics card?" Wang Haowen shook his head quickly, "You dare to give me these billions of part-time jobs, but I don't dare to take it. Do you know how much work this is?"

"My requirements are not that high, as long as it can run, I don't care about optimization. And it doesn't have to be written from scratch. You can use Invida's driver to modify it. This is not a commercial version, and you don't need to consider patents. The issue of infringement.”

After listening to Kang Chi's request, Wang Haowen really thought about the feasibility carefully.

The function of the driver is to control the chip switch.

The most complicated thing is the set of control logic behind it.

Then there are VID and PID used for communication.

For example, if each transistor on the hardware is a soldier, then the driver is the command center behind.

VID and PID are the telephone lines connecting the command center and soldiers.

According to Kangchi's requirements, as long as the graphics card can be run, it is not difficult.

Just debug the phone line and that's it.

As for whether there will be a naval command center, it is connected to the army corps. In the end, the soldiers sleepwalked on the battlefield...

There is no need to consider these.

That's something that would cost hundreds of millions, or even billions, to debug.

After thinking for a long time, Wang Haowen nodded: "I can try, but there is no guarantee of success."

"no problem."

Kang Chi suddenly showed a happy smile, "Then what do you think is the appropriate price for this part-time job?"

Wang Haowen thought for a while and then said shyly: "How about 100,000? The main thing is that I can't do this alone. I have to ask my classmates for help. In addition, I have to borrow the equipment of the institute to deduct these costs." , after all calculation, I actually can’t earn much..."

"Can't make much? Then 150,000!"

Kang Chi waved his hand directly.

Wang Haowen was able to help him so enthusiastically last time, so Kang Chi would naturally not be stingy with him.

"However, the extra fifty thousand will be given to you as a reward after the work is completed."

Damn it,

The boss is awesome!

Wang Haowen immediately succumbed to Kang Chi's money offensive and secretly vowed to complete the task.

Although he is a doctoral student, he has not graduated yet.

The economy is actually not well off either.

What's more,

So what if I have a doctorate?

Not everyone earns a million dollars a year after graduating with a doctorate degree.

There are many people who earn only 20,000 to 30,000 yuan a month.
