With the help of Liu Yu, Kang Chi spent almost four days and finally successfully developed his graphics card prototype!

Looking at the half-palm-sized integrated circuit board in his hand, Kang Chi couldn't help but sigh.

Chips are really hard to make!
It is such a thing whose performance is almost eliminated nowadays. With so many ready-made equipment and Liu Yu's technical support, Kangchi also tried more than ten times before finally succeeding.

To put it simply, the chip thing is to solder diodes. The more diodes, the stronger the performance.

Take building a house as an example. A diode is a brick, and the current international mainstream chip is a city.
As for the house in Kang Chi's hands, it is at best a slightly complicated house.

but that's okay,

As long as the system is upgraded, the structures of high-rise buildings will become more and more complex and efficient.

After Kang Chi put away the graphics card, he nodded gratefully to Liu Yu: "I've really troubled you these past few days."

"It's okay. Anyway, there are no orders now, so I'm free." Thinking of the 5 yuan given by Kang Chi, Liu Yu smiled sheepishly, "And it's not like you didn't give me the money. I should thank you." You are right."

"But to be honest, you are quite talented at this. I originally thought it would take at least a week for you to learn how to use these devices, but in the end, you made the card in less than four days. "

Kang Chi smiled: "I used to repair cameras, so I might be pretty good at this kind of delicate work."

"No wonder, repairing a camera is also a technical job, and the principles are actually the same."

After finishing the graphics card, the two had dinner together, and then Liu Yu drove Kang Chi to the train station in his second-hand Arrizo.

"Come to our Dongyang to have fun if you have the chance."

"Well, I'll definitely come when I have time. Have a nice trip."

The two said a simple goodbye, and Kang Chi got on the train back to Dongyang, ending the journey perfectly.

After returning home, Kangchi immediately took out the graphics card and upgraded it using 20 general experience.

A glimmer of light flashed. The appearance of this image processor did not change much, but its properties were greatly improved.

[Item: Silicon Image Processor]

[Manufacturer: Kangchi]

[Item level: 2]

【Experience: 0/50】

[Item status: intact]

[Item parameters: 12 micron manufacturing process, main frequency 64MHz, video memory 520KB]

[Analysis item: parsable]

[General experience: 633]

[Mastery Points: 18.6]

Although the parameters have been improved nearly ten times, it is not enough!
Keep upgrading!

General experience-50,
-
100,
-
400,

After three consecutive flashes of light, the appearance of the graphics card has changed significantly. Not only has it become larger, but it also has additional heat-sink aluminum fins and a heat-sink fan.

Finally it looks like a graphics card.

[Item: Silicon Image Processor]

[Manufacturer: Kangchi]

[Item level: 5]

【Experience: 0/800】

[Item status: intact]

[Item parameters: 40nm manufacturing process, main frequency 512MHz, video memory 521MB]

[Analysis item: parsable]

[General experience: 83]

[Mastery Points: 18.6]

The graphics card that has been upgraded to level 5 has finally entered the 40nm process technology, and its performance is only slightly lower than the GTX5 series graphics card released by Invida ten years ago.But it's still not enough.

Although Kangchi does not hope to suddenly create a graphics card that surpasses Invida when the time is not yet ripe,

It's too easy to be suspicious.

He needs to gradually let the market and the public recognize and accept himself, and achieve transcendence at the right time.

But this does not mean that he has to start with products of the GTX550 level...

It's too low end.

After all, it has to be at the level of GTX1050, right?

But the problem is that he doesn't have enough general experience now...

So Kang Chi, who was very itchy, immediately rushed to the company and entered the return warehouse of Daqin Optics.

At Daqin Optics, there is a rule that everyone has always found strange:

All user returns, free exchanges and free replacement products must be centralized in this "return warehouse". Only returns that have been "inspected" by Kangchi can enter the next step of processing.

Thanks to Soni's smear campaign against Daqin Optics some time ago, nearly a thousand lenses have accumulated in this return warehouse.

"Switch, switch, switch!"

Uh,
Why do I feel like I am practicing the magic of absorbing stars...

Kang Chi checked the attribute panel while switching to general experience.

Huh?
653 point of experience?
This lens experience really overflowed!
[Item: 35mm F1.4 lens]

[Manufacturer: Daqin Optics]

[Item level: 2]

【Experience: 653/400】

[General experience: 369]

[Mastery Points: 18.6]

[Item status: good]

[Analysis items: no analysis items]

Looking at the lens in his hand, Kang Chi burst into laughter.

This means that not only can he get a level 3 lens right away, but he can also save valuable general experience.

"I didn't expect to have an unexpected harvest today!"

Kangchi upgraded this lens without hesitation.

A flash of light flashed. The 35mm humanistic lens became slightly larger and heavier. There was also a small AF/MF switch on the side of the fuselage.

The moment Kang Chi saw this switch, he was ecstatic.

As expected,
This lens finally has autofocus!

Although the appearance of the lens has not changed much, Kang Chi knows very well that the structure inside must be many times more complicated than before.

The principle of lens autofocus is actually very simple. It is to install a small electric motor inside to drive the lens to move forward and backward to achieve precise focusing.

The principle is simple, but the actual design is not easy at all.

First of all, the lens needs a system that interacts with the camera to know how and how much the lens should move.

Sometimes the error may be just 1 millimeter or 0.1 second, and the focus will stutter, causing the user's experience to plummet and classify it as a junk lens with unavailable autofocus.

Secondly, this small electric motor is not an ordinary motor.

It needs to meet various requirements such as small size, high precision, quick start and stop, excellent silence, etc., and its technical content is no lower than that of lenses.

After upgrading the lens, Kangchi did not rush to test it, but continued to convert the universal experience. After processing the pile of recycled lenses, the universal experience increased to 1280 points.

That’s enough for a graphics card upgrade!
