"Why does ASUS have at least 6 different types of boards for the same 845 motherboard? "
Zuo Wangdao blinked and replied quickly, "It's because different materials are used for different users. For example, Sanyo is divided into Sakura Origin Sanyo and Yizhou Purple Sanyo. Nichicon also has Yizhou Nichicon lf, and the performance of the two is different."
Qing Yun asked Yang Bingnan to bring in two cigarettes, opened them on the table, and told them to take them by themselves and take care of themselves. Li Ran took two puffs, and then said slowly,
"Take ASUS as an example, it has different suffixes, k is the most entry-level level at present, focusing on cost-effectiveness; d is similar to k, but It pays more attention to commercial expansion excuses; e is positioned between kd and kd." At this point, he shrugged, "In fact, there is no difference between the three materials."
"Damn! The price difference is huge!" Huang Yingbin complained excitedly, "What a profiteer!"
Qing Yun shook her finger, "The price is reasonable, listen. After I finish speaking, you can scold me again."
Obviously, this is a "victim."
“The p suffix refers to a low-end motherboard that supports overclocking; a is a mid-to-high-end representative of overclocking motherboards, which has more interfaces than p, and plus is an enhanced version of a.
There is no difference in the actual materials used among these three.
C or cms are commercial series motherboards, which are only used by industry customers. The materials used are exactly the same as the three above. ”
< p>Speaking of this, Qing Yun picked up the two packs of cigarettes on the table and placed them on both ends of the coffee table."I tell you, the distance between good and bad computer hardware is long. "
He sat back and continued, "Tell me something you are more familiar with, such as CPU..."
Qing Yun smiled playfully, with a smile on his face. It was all a joke, "Lao Zuo, you, Guang Yi, and Lao Huang all were given computers by your family during the summer vacation in your third year of junior high school.
I remember that you all bought Celeron 300a pairs. Right?"
At this time, all the boys laughed at first, and then burst into laughter.
Zuo Wangdao’s complexion is not much different from that of pig 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, was looking at these idiots with a confused look on his face.
Zuo Wangdao was so angry that he laughed, "Damn it! I'm so angry when you mention this!
I'm so unlucky!
The three of us installed machines at a computer shop, with exactly the same configuration, and the CPUs were all Celeron 300a.
It turned out that Huang Yingbin’s CPU could exceed 450mhz, and that guy Shi Guangyi’s was even more outrageous. Go directly to 504mhz, which is stable.
As for the shabby one I have, nothing will happen if it is not overclocked. Once it is overclocked, it will crash!
I was not willing to give in, so I changed to a better fan and forced it to exceed 450mhz. However, within a month, the computer started to smell burnt, and I was so scared that I quickly adjusted the frequency back.
Do you think it’s strange or not? They all have the same configuration. I measured the voltage and it was stable. I even bought a voltage regulator...”
The more he talked, the more excited he became. , as if returning to that depressing summer.
A few girls were also fascinated by it. They did not expect that a small CPU could have so many stories.
While Zuo Wangdao was talking, he suddenly came to his senses. He looked at Qing Yun doubtfully,
"Old Qing, what you mean is that this is not due to luck, but from the same batch. Is there really a difference between the CPUs in them? And you can see it? ! "
There is definitely a difference between the same batch of things. He still knows this. He can only say that he is unlucky.
But Qing Yun just said that, obviously... ...
Qing Yun nodded affirmatively, and then said with a smile, "CPUs have physical differences.
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 go very high, while others are unstable if they go a little higher. It's just like people, everyone has their own strengths and limitations.
Both Intel and AMD can clearly know their physical condition and will inform the merchants. "
He continued, "Take the Celeron 300a as an example. You have also seen that some can exceed 450mhz and some can reach 504mhz. But do you know that there is actually another type that can exceed 450mhz? to 603mhz? ”
Celeron 300a is a miracle, and it even brought about the popularization of DIY culture.
Everyone’s eyes widened when they heard this.
It is normal for 300a to exceed 450mhz, but it is rare to exceed 504mhz, but they have never heard of 603mhz.
Qing Yun smiled, "What is the difference between the same CPU? It is the constitution at birth. When the CPU is produced, its constitution is actually completely different due to the different processes and the position of cutting the wafer. ”
He explained that due to small differences in the manufacturing process, even CPUs coming off the same production line will have performance differences.
“It’s inappropriate to say For example, if you pass 60 points, you can't overclock the Celeron 300a, if you get 70 to 80 points, you can maintain overclocking at 450mhz, if you get 80 to 95 points, you can overclock to 504mhz, and if you have over 95 points, you can reach 603mhz. "
Wu Yihang was thoughtful after hearing this, and then asked, "You said that both CPU manufacturers and buyers know it, so what you mean is that there is actually a price difference between good and medium CPUs. ? ”
Qing Yun nodded when he heard this, "Yes, the best ones must be branded machines, especially branded machines that pursue quality. They will use the best CPUs to make servers or high-end business machines. ."
"The high-quality products are the mainstream models of brand-name machines, and the mid-range products are in the hands of retail investors." Wu Yihang understood and said smoothly, "The bad ones are the ones. It will be eliminated, 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."
< p>Zuo Wangdao complained angrily, "The Celeron 300a that cannot be overclocked is a piece of shit."Qing Yun smiled, for players who love DIY and overclocking, CPUs that cannot be overclocked are indeed Not very attractive.
"It's really a piece of shit, but," he shrugged and continued,
"The needs in the market are diverse. Not everyone needs to overclock. CPU. Some people may only use it for surfing the Internet and working. For them, a stable CPU that does not require overclocking is more suitable."
"Moreover," Qing Yun added, "These. The price of the CPU will be lower, which is a good choice for consumers with limited budget."
Gou Dan seemed to understand what Qing Yun meant at this time, "I understand, that's all. 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 have different needs. Consumer demand."
"But, it's a Celeron 300a, which fool would want one that can't be overclocked? I mean, if you know! Zuo Wangdao's words made everyone happy.
"How the hell did I know that what I bought was not a super one!"
And he himself grabbed a cigarette depressedly and lit it.
Qing Yun patted Zuo Wangdao's shoulder gently, "There are still merchants who want it, such as the Shenzhou computer that Gou Dan just mentioned. How do you think it can achieve "the same price and configuration" "The best, the cheapest one with the same configuration?"
Yun Emperor's face showed a look of reminiscence, and he began to talk about Wu Junjun's "mistress theory".
"Wu Junjun once said such a theory - the "mistress" theory, that is, the third choice theory.
He used this theory to choose the third choice in the market Choice - not the best, not the worst, but the most cost-effective.
So what is the most cost-effective?
For example. Is the Celeron 300a sold to you by Shenzhou a qualified Celeron 300a?
It just cannot be overclocked.It just might break after 3 years.
But when you choose a computer, is its configuration list clearly Celeron 300a? It’s also not prone to problems during the one-year warranty.
You can't say that he passed it off as a good product. What he got was a qualified product, but the quality was 60 points. "
When everyone heard this, they immediately started yelling, "The stupid army army is so heartless. Isn't it deceiving people by lowering the price like this?
Huang Yingbin patted her chest fearfully and said to Qing Yun, "Fortunately, you acquired Shenzhou Computer, otherwise we consumers would be unlucky." "
At this time Li Yali intervened, "But... this kind of behavior should not be hidden, right? Won't other manufacturers attack him? "
"Why can't you attack... Hey! "Huang Yingbin was stuck.
He suddenly realized that Shenzhou Computer was indeed criticized by major manufacturers for engaging in price wars and engaging in low prices and low quality, but it was always about the materials used, such as Shenzhou's board capacitors.
No one has ever said like Qing Yun that the CPU they use is itself...
A group of boys also understood and grinned. .
What the hell, it really can’t be criticized. Others use components purchased through formal channels.
And...
They are all used. Not being a fool, they all turned their attention to Qing Yun, who was over there.
Zuo Wangdao swallowed hard, "Old Qing, don't tell me, in fact, all manufacturers are doing this. Have fun! "
Qing Yun replied with eight teeth, "Other brands don't dare to lift the table and pierce this layer of paper because everyone's buttocks are unclean.
If you don’t get 60 points on the CPU, you will get 60 points on the motherboard, on the monitor, on the memory, on the hard disk...
And just like our college entrance examination scores, Those with 60-70 points in each subject, that is, the total score between 450 and 525, are the largest number of reference people.
For CPU manufacturers, if these CPUs are not allowed to enter the market and are scrapped, then the production cost will skyrocket, and it will be unstoppable.
So CPU manufacturers will give different quotations for each category according to the different characteristics of the CPU, or give them priority to purchase.
For example, Intel's sales partner system is hierarchical. Different levels have different business conditions. In addition to different sales rebates, they also have the right to choose CPUs. ”
