Chapter 998 A CPU that cannot be overclocked is a piece of shit
'Why does ASUS have at least 845 different categories of motherboards for the same 6 motherboard?'

Zuo Wangdao blinked and answered quickly, "It's because different materials are used for different users. For example, Sanyo has Sakura Original Sanyo and Izu Purple Sanyo, and Nichicon also has Izu Nichicon LF. The performance of the two is different."

Qing Yun asked Yang Bingnan to bring in two packs of cigarettes, opened them and placed them on the table, motioning for them to take them themselves. He lit up and took two puffs, then slowly spoke,

"Take ASUS as an example. It has different suffixes. K is the most entry-level product at present, focusing on cost-effectiveness; D is similar to K, but focuses more on commercial expansion interfaces; E is positioned between K and D."

At this point, he shrugged his shoulders and said, "Actually, there is no difference in the materials used in these three models."

"Damn! The price is way off!" Huang Yingbin complained excitedly, "What a fucking profiteer!"

Qingyun shook his finger, "There is a reason for the high and low prices. Listen to me before you scold me."

Clearly, this is a 'victim'.

"The P suffix represents a low-end motherboard that supports overclocking; A represents a mid-to-high-end overclocking motherboard, which has more interfaces than P, and PLUS is an enhanced version of A.

There is no difference in the actual materials used for these three, they are the same materials.

C or CMS is a commercial series motherboard, dedicated to industry customers, and uses the same materials as the previous three. "

At this point, Qing Yun picked up the two packs of cigarettes on the table and placed them at the two ends of the coffee table.
"Let me tell you, the distance between good and bad computer hardware is long."

He sat back in his seat and continued, "Let's talk about something you are more familiar with, such as the CPU..."

Qing Yun smiled playfully, his face full of joking, "Lao Zuo, you, Guangyi, and Lao Huang, the three of you were all given computers by your family during the summer vacation in the third year of junior high school.

I remember you all bought Celeron 300A, right? "

At this point, all the boys first chuckled, and then burst into laughter.

Zuo Wangdao's face looked not much different from that of a pig's liver.

The girls all looked at them blankly, not knowing what these people were doing.

Even Mr. Chen, who was most concerned about computers at the moment, looked at this group of crazy people with a confused look on his face.

Zuo Wangdao was so angry that he laughed, "Damn it! I get angry when you mention this!

I have such bad luck!

The three of us installed our machines at a computer installation shop. We had exactly the same configuration, and the CPUs were all Celeron 300A.

As a result, Huang Yingbin's CPU could be overclocked to 450MHz, and Shi Guangyi's was even more outrageous, directly reaching 504MHz, which was extremely stable.

The crappy one I have works fine when I don’t overclock it, but it freezes when I overclock it!
I was not willing to give up, so I replaced it with a better fan and forced it to exceed 450MHz. As a result, within less than a month, the computer started to smell like it was burning. I was so scared that I quickly adjusted the frequency back.

Don’t you think it’s strange? They are all the same configuration, and the voltage I measured is stable. I even bought a voltage stabilizer…”

He became more and more excited as he spoke, as if he was back in that depressing summer.

Several girls were also fascinated by the story. They had never expected that a small CPU could hold so many stories.

Zuo Wangdao suddenly realized what was happening. He looked at Qingyun in confusion.

"Lao Qing, what you mean is that this is not due to luck, but that there are really differences between the CPUs in the same batch? And you can see it?!"

It is certain that there are differences between things in the same batch, and he knows this. He can only say that he was unlucky.

But Qingyun just said that, obviously...

Qing Yun nodded affirmatively, then smiled and said, "CPUs have different physical qualities.

Although each CPU has the same model, due to slight differences in the production process, the overclocking potential of each CPU is different.

Some can reach very high levels, while others become unstable after a little overreach. It's just like people, everyone has their own strengths and limitations.

Both Intel and AMD are well aware of its performance and will inform the merchants.”

He continued, "Take the Celeron 300A for example. As you can see, some can go up to 450MHz, some can go up to 504MHz, but did you know that there is actually one that can go up to 603MHz?"

Celeron 300A is a great CPU, and it even brought about the popularization of DIY culture.

When everyone heard this, their eyes widened.

It is normal for 300A to exceed 450MHz, but it is rare to exceed 504MHz. However, they have never heard of 603MHz.

Qing Yun smiled and said, "What is the difference between the same CPU? It's the physical properties when it is born. When the CPU is produced, due to the different processes and the locations of the wafers cut, the physical properties are actually completely different."

He explained that due to slight differences in the manufacturing process, there will be differences in performance even if the CPUs come off the same production line.

"To make an inappropriate analogy, a score of 60 is a passing score, which means that the Celeron 300A cannot be overclocked. A score of 70 to 80 is guaranteed to be overclocked to 450MHz. A score of 80 to 95 can be overclocked to 504MHz. A score of 95 or above can reach 603MHz."

Wu Yihang seemed to be thinking about what he said, and then he asked, "You said that CPU manufacturers and buyers all know this, so what you mean is that there is actually a price difference between good and bad CPUs?"

Qing Yun nodded when he heard this. "That's right. The best ones are definitely for branded machines, especially for those who pursue quality. They will use the best CPUs to make servers or high-end business machines." "And the good ones will be the mainstream models of branded machines, and the mid-range ones will be in the hands of retail investors."

Wu Yihang understood and added, "Then the only thing missing is elimination, right?"

Qing Yun shook his head and said, "No, it will not be eliminated. The Celeron 300A that cannot be overclocked is still a qualified product, it just cannot be overclocked."

Zuo Wangdao complained angrily, "The Celeron 300A that can't be overclocked is just a piece of shit."

Qing Yun smiled. For players who love DIY and overclocking, a CPU that cannot be overclocked is indeed not very attractive.

"It's a piece of shit, but," he shrugged and continued.
"The demands in the market are diverse. Not everyone needs an overclocked CPU. Some people may just use it for surfing the Internet or working. For them, a stable CPU that does not require overclocking is more suitable."

“Moreover,” Qingyun added, “these CPUs will be priced lower, making them a good choice for consumers with a limited budget.”

Gou Dan seemed to understand Qing Yun's meaning at this time, "I understand, just like when we go to the supermarket to buy milk, some milk has a long shelf life, some has a short shelf life, and the price will be different."

Qing Yun smiled and nodded, "Yes, that's the truth. Different products meet the needs of different consumers."

"But, it's already a Celeron 300A, what idiot would want one that can't be overclocked? Uh... I mean, if I knew!"

Zuo Wangdao’s words made everyone laugh.

"How the hell did I know that the one I bought was one that couldn't be overcharged!"

He grabbed a cigarette and lit it up in frustration.

Qing Yun gently patted Zuo Wangdao's shoulder and said, "There are still businesses that want it. For example, the Shenzhou computer that Gou Dan just mentioned, how do you think it achieves 'the best configuration at the same price, and the cheapest at the same configuration'?"

A look of reminiscence appeared on Yundi's face, and he began to recount Wu Lujun's "mistress theory".

"Wu Lujun once said such a theory - the 'mistress' theory, that is, the third choice theory.

Using this theory, he chose the third option in the market - not the best, nor the worst, but the one with the best value for money.

So what is the most cost-effective thing? It is something with poor physical condition.

For example, the Celeron 300A sold to you by Shenzhou, is it a qualified Celeron 300A? Obviously it is.

It just can't be overclocked, and it might break after 3 years.

But when you choose a computer, is its configuration list clearly Celeron 300A? It is not easy to have problems within the one-year warranty period.

You can't say he was selling inferior goods as good ones. What he got was a qualified product, but the qualified product was only 60 points."

When everyone heard this, they immediately started cursing, "Damn Wu Lujun is so heartless. Isn't it cheating people by lowering the price like this?"

Huang Yingbin patted his chest in fear and said to Qingyun, "It's a good thing you acquired Shenzhou Computer, otherwise we consumers would be in trouble."

At this time, Li Yali interrupted, "But... this kind of behavior should not be concealed, right? Won't other manufacturers attack him?"

"Why can't I attack...Eh!" Huang Yingbin was stuck.

He suddenly realized that Shenzhou computers were indeed criticized by major manufacturers for engaging in price wars and offering low prices and low quality, but the criticism was always about the materials used, such as the capacitors on Shenzhou's boards.

But no one has ever said like Qingyun that the CPU they use is...

The boys also understood and grinned.

Damn, there's really nothing to criticize. Others use components purchased from regular channels.

and……

They were not fools, and all turned their eyes to Qing Yun who looked calm and composed over there.

Zuo Wangdao swallowed hard, "Old Lord, don't tell me that all manufacturers are doing this!"

Qing Yun gave him a stern response, "Other brands don't dare to lift the table and break this layer of paper because everyone has a dirty bottom.

If you don't get 60 points on the CPU, you will get it on the motherboard, the display, the memory, the hard disk...

And just like our college entrance examination scores, the number of people who scored 60-70 points in each subject, that is, between 450 and 525 points in total, is the largest number of candidates.

For CPU manufacturers, if this batch of CPUs is not allowed to enter the market and is scrapped, the production cost will rise sharply and cannot be stopped even if it doubles.

Therefore, CPU manufacturers will give different quotations for each category, or give priority purchase rights, based on the different physical properties of the CPU.

For example, Intel's sales partner system is hierarchical, and different levels have different business conditions. In addition to different sales rebates, they also have the right to choose CPUs. "
