Forehead...... Ironmen, I'm always picking up garbage. Today, let's briefly talk about the 2024 version of the notebook procurement proposal of the garbage guy. In fact, it is some of the questions that the group friends asked us before, and we see that it may be helpful to you, so I will sort it out and send it.
This article has actually been written once before.,But we're forced to rewrite it again.,The reason is very simple.,Zhihu swallow the draft is okay.,We just planned to refresh it and prepare to copy it, and the content is directly gone.,But this content can't be just wanted.,We don't know how to recover it.,So we can only rewrite it.。
Fortunately, we basically remember the content, but this blood pressure is a little up. You should consider if there is a better editor in the future.
To put it simply, this time the group members gave a proposition composition, and the time and product model have been set directly, and the only thing that needs to be asked is the location.
The configuration requirements are 4060/4070, i5, 144hz refresh 2k or more resolution, 1T solid-state. In fact, it's mainly the Great War Mi Dimension Family Bucket (including the future Jeopardy Zero).
At this stage, we don't recommend that you buy large-capacity solid-state when you install it, because last year, if you have seen the counterattack of domestic flash memory, you should actually know that solid-state was the cheapest last year, because foreign brands led by Samsung were 96% The loss of production and price reduction also has to fight a price war with domestic flash memory, as a result, domestic flash memory not only has no trend but wins the volume, resulting in them now fire, earthquake, water and power outages, and manufacturers such as the Yangtze River have also successfully resisted sanctions and used domestic production equipment to expand production and successfully fight against encirclement, so the price reduction of flash memory in the future is predictable, and it is usually believed that the price can be reduced at the end of the year, but it is not known whether it will return to the price war period.
Secondly, we took a brief look at the configuration requirements of Jeopardy 0 and found that it is quite high:
10th generation I7If you don't consider the notebook, it's actually already at the level of 8C16T, but there are also garbage picking options with similar performance, but it's still not suitable.
1151 is a customized version of CC150 8C16T U and the main frequency is not low, but there is no nuclear display. The current version does not have a core display, in fact, 1151 is still a loss,Because the motherboard itself is designed with a core display,Plus1151It is basically the P106 version of the answer,The CPU level just won't limit the play of the GPU too much(1225V3 or something like that,It's just usable),So this set of configurations without a core display is compared to the figure of the standard X99 will still lose the budget。 Even if the level of this U is enough for a card such as 5600XT, but P106There are actually more high-end cards such as P40 and 40HX, so there will be more or less losses if you don't have a nuclear display.
The 1151 platform itself does not match the coreless display, like the 9100F and 9400F that were bought cheaply in the later mining disaster, P106 is basically unusable. This is a person who has no long-term worries, and there must be near-term worries.,Cutting the nucleus and showing U looks a little cheaper.,I bought a picture cheap.,It turned out that the loss of bitter tea was in the back.。 In short, if you install it according to this configuration demand, let's put it on hold, we have the confidence that after the Jeopardy 0 is released, the budget of the whole machine will be pressed below 1000.
Back to the question of this issue,Let's take a brief look at the configuration requirements,Found that the 10th generation I7 is actually like that in retrospect, the current game book AMD doesn't know what level,IU's INTEL CPU is basically changed after the 12th generation, the architecture process has been changed,SO EVEN I5 SHOULD BE ABLE TO WIN THE PAST I7,THE PROBLEM IS NOT VERY BIG。
And most games can be low U high display, high U low display is not the same card as the card.
Then we took a brief look and found that 4060M is the full version of the AD107 core, and 4070M is the complete AD106 core. So in the end, the suggestion is that the group friends can concave 4070 or preferentially concave 4070, CPU I5 is fine.
Here is a brief introduction to the situation of the game book,It is recommended to still have a high and low U and not a high U low display,Unless the barebones U and the graphics card can be replaced,Otherwise, it is better to play games with low U and high display。 This is said on the premise that the graphics cards are all native cores that have not been hacked.
Here are some practical reasons for choosing this strategy.
Group friends: Five or six years ago, I bought HP like this, and the 10 series graphics cards hadn't come out yet, and I bought a 960m for 7000 yuan.
At that time, when the garbage guy heard the 960M, the first thing he remembered was the abstract naming method of NVIDIA on the notebook and the big knife method of the 900M series graphics card.
I REMEMBER THAT AT THAT TIME, NVIDIA PROCESSED A LOT OF MAXWELL LEFTOVERS ON THE LAPTOP, RESULTING IN THE GTX900M GRAPHICS CARD BASICALLY USELESS, IN SHORT, IT WAS BASICALLY ALL CUT CORE, WHICH WAS VERY DIFFICULT TO USE.
For example, we are now coding this machine,GPU is GK104 cut big residue,Normal should be 8 groups of SMX units,As a result, only 3 groups can be used on this K3000M,Even this card is also locked driver,Can't get on the latest version of GK104 core game cards like GTX680。
It's just that the CPU GPU of this machine can be replaced,The graphics card is MXM's can be changed casually to 1066 or something to solve the problem,This machineDC2 screen supports eDP can be on a very new graphics card,And most of the graphics cards of the game book can't be replaced,What you buy is what。
In fact, if the chip product with the same process architecture is the same as the core of the chip product, the closer to the available core scale is the higher the energy efficiency, the best is that the number of native cores is equal to the actual number of available cores. On the importance of this theory, we will change it later.
For GPUs, with the same number of stream processors as the process architecture, the uncut cores are less hot, and the theoretical performance is higher.
Most chip products are cut because of their own defects, but there are a few exceptions, such as AMD's open core of some CPUs and GPUs, because the cut core is essentially not defective, and it is purely artificially reduced the price of the product and cut it to distinguish grades. If you can use this part of the cut core, it is best to use it directly. The severed core will still heat up when energized. If you don't have to leave it here, it will only increase power consumption and heat, and it can also provide performance.
In any case, it is recommended to use the full version of the core product for the notebook, and the core that has been used by the knife method will more or less cause the situation of useless transistors heating and power consumption, which will also cause the loss of performance and battery life and a higher heat dissipation burden for the notebook.
But the group friends before 960M is really not GM204 big remnant,This core is750Ti with the same modelGM107,The frequency is about the same level,In fact, it is equivalent to750Ti plus 4G video memory on the notebook,Although today it seems that the designation is very backward, but at the time it was OK,And the core is native,There is no problem with knife skills,It's actually pretty good。
There is actually only one of the abstract graphics cards in the GTX 900M that is really easy to use, that is, the 965M2 of the original GM206 (the new version of the 965M), which is the GM206 core of the same model as the core GTX960, and it is also the full version. The performance is similar to that of the GTX960, and its professional version is the M2200M, which is also the full version of the GM206 core. GM206's video codec is stronger than GM204, and it is actually better to use than the core cut by GM204.
As for other abstract 3D accelerator cards like 940MX, it is basically impossible to see, and here the group friends have encountered follow-up products with the same positioning:
What level of GPU is MX250? It does not support video output and encoding and decoding, it is completely a P106-like computing card or 3D acceleration card, relying on the core graphics work, unable to undertake the work of the graphics card independently.
And its performance is really not as good as 750TI, that is, 960M before the group friend, 7850 2G for 100 yuan, and the performance is almost 1.5 times that of it......
Garbage guy: This thing isn't as good as your previous 960M
Group friend: Yue, vomited
So compared to the garbage picking group desktop,There are actually more pits in the notebook,Like MX Family, which has not been updated, the bright machine card leftovers have been changed3D accelerator card product line has been stopped, and more teenagers can actually be used with the 10th generationU, we didn't expect it (and the 10th generationI7Low voltage U is also only 4C8T, which is also abstract enough,I7I'm afraid I can't beat I3 10100)。 In retrospect, this thing is only a limited level of strength than the nuclear display. It can only be said that the MX series is quite good, and in theory, it is actually a separate display (broadly speaking, the P106 computing card can also be a separate display).
The most abstract is that my friend who shelved Genshin Impact spent 8000 to buy a Dell notebook, and the result was 1080P in the image quality card, and the result was a look at the Xe core display...... (Finally retired)
It can only be said that notebooks are only more abstract, not the most abstract.
So we actually want to persuade the group not to buy a notebook, but we don't emphasize that people have to buy it, after all, there must be a reason to buy a notebook.
Therefore, we can only use our previous experience of buying a notebook to talk about what we need to pay attention to when choosing a notebook at this time.
This looks like a game laptop, but it's actually a netherworld machine, and it's the kind that I haven't gotten over for years at the level of PTSD.
It was put on the car by an acquaintance before the mine tide, but after getting in the car, it was found that it was a hearse, which was bought for 4000 at the end of 2020, and it was found that the fish could not be used at all 3000, and it was really directly exploded by the old Bi Deng, and the result was expensive, even if it was uncomfortable to use, it was not as cheap as picking up the old workstation.
1. Direct connection of independent display
First of all, you can see that this GPUz shows that there are two graphics cards, and this is where the first pitfall of this machine comes in. Its display is not directly connected to the independent display,The independent display is actually still used for nuclear display acceleration, and it can't be directly used for video output,The performance of the independent display will be discounted by about 20%,1050The video signal is already weakUHD630This is even more unsightly。
And this kind of notebook without independent display direct connection wants to solve the problem of independent display direct connection and has to divide the machine,Some machines can switch independent display direct connection,Some can't switch at all,Like the garbage guy's underworld machine, if you want to output video signals from independent display, you can only insert a monitor,Some can't even plug in the display with independent display output,There is no place to output video signals to independent graphics cards at all, but they can only be displayed by the core,This worst means that the performance loss of the independent graphics card is unavoidable,In any case, it must be charged by the nuclear display。
(Group friends: My younger brother has a mechanical revolution 4060 series laptop, and he told me that his machine needs to be manually controlled to turn on the direct connection of the independent display, I don't understand.) Why don't manufacturers directly connect all good graphics cards directly to the independent display garbage guy: The independent graphics card can be turned off directly on the notebook that is not directly connected to the independent display, mainly to save power when considering the use of the battery)
If you like a group of friends who use the notebook as a mobile desktop, in fact, it is better to buy a gaming laptop without a direct connection to the independent graphics card, it is better to buy a notebook that shields the core display and pure independent display output, such as the garbage guy's 8770W mobile workstation is to shield the CPU core display and only leave the independent graphics output, so if you use a graphics card without video output, the screen will be black (such as P106 MXM).
2. Heat dissipation design
The second pit is this book's I7+1050 configuration result, the heat dissipation is very rubbish,Resulting in no pressure at all, you can only reduce the frequency of I7 as I5, and even turn off the hyper-threaded card in order to reduce power consumption15W power consumption wall as a low-voltage U use。
Most of the laptops that the garbage guy has seen have side blowing or rear exhaust air for heat dissipation,But DELL, this underworld machine, blows air directly from the crack of the screen shaft to the screen,This design has only been seen on MacBook in the past,So we don't want to say how about this machine with only two heat pipes,The design of this air outlet alone can suppress the I7 8750H+10 series graphics card.
The result is that this 8750H CPU is not as good as the 3820QM used by the garbage guy later after reducing the frequency and voltage power consumption, so the most important thing in the notebook in addition to the configuration is to look at its heat dissipation, and if the heat dissipation is not good, it is really not good, no matter how good the configuration is, it can only be reduced and the anus can be reduced, and it can't be used well at all.
3. Process technology
The third is that the process of this graphics card also has pits,Samsung14nm1050M was originally the residual blood core of GP107,As a result, the process itself is still more pulled than TSMC16nm,Resulting in higher performance heating。
Let's look at the parameters here,1050M's TDP is75W,30W higher than I7 8750H's45W,The result performance level is only 650Ti boost or HD7850 level,The result1060M's TDP is80W,However, the power consumption is 5W higherThe result is that the performance has reached the level of RX570,The performance is directly doubled。 This excludes the factor that GPU core frequency reduction can also improve energy efficiency, in fact, the rest is completely due to process and knife method.
Samsung's 14nm process has a lot of pits, I'm afraid you can ask everyone who has used 10 series graphics cards, you can know, you don't need to mention Apple's A9 lottery door, you can see it from this. With the same architecture and different processes, there can be a considerable gap in energy efficiency.
By the way,Is there a TDP of 1050M in the end75W?The garbage guy thinks there is absolutely yes,After all1050/1050TiThe TDP is 75W,In fact, looking at the core scale, the SP of 1050 is exactly half of 1066,As a result, the power consumption is already higher than half of 1066。 It shows that the knife method + Samsung's pulling process is to blame.
DELL 3579 If the machine does not press the CPU frequency, let the GPU go and run it can reach 100°C, even if the CPU frequency and power consumption wall are pressed when running AI, it is still 95°C daily, even if the TDP of the CPU is pressed to 15W, when the low voltage U is used at the same 90 degrees, it is 90 degrees, so it is no problem to think that the majority of power consumption is in the graphics card.
The 1050M is a remnant version of the GP107 core, which has 1/6 of the core chopped. That is to say, under the premise of losing 1/6 of the performance out of thin air, it has the same power consumption as the 1050Ti M
However, the 1050Ti M may not necessarily be the full version of the GP107, and there may still be a cut version of the GP106. However, in a sense, if the lesser of two evils is chosen, then Samsung's defense process is far more terrible than taking a knife. Perhaps the knife version of the GP106 is more energy efficient, with higher performance and better use with limited power consumption.
A glance at the GP106 TSMC version of the 1050M, the energy efficiency of the finch is higher, the frequency is higher under the same power consumption, and the performance of the core of the cut core is one-fifth higher than that of the full version of the core. Explain that the energy efficiency of TSMC's 16nm FF+ process is at least 20% higher than Samsung's 14nm.
Who says 14nm is necessarily better than 16nm? Samsung's 14nm graphics card is not necessarily as energy efficient as TSMC's 28nm.
For comparison, the TDP of the M2200M using the 28nm GM206 core is 55W, but the performance is only 14% worse than the 960/1050Ti M, only 22% worse than the 1050Ti, and the power consumption is 36% lower, and the TSMC 28nm is really not worse than the Samsung 14nm in terms of energy efficiency.
So why did the garbage guy have to specifically confirm the process and knife method of the 40 series graphics card at the beginning, mainly because he was afraid of the pit in the past.
By the way, the MX250 of the thin and light book of the group of friends also stepped on the same Samsung 14nm defense process, this thing is even compared with MX150 is only a little more than the official frequency, only tens of Mhz. It is equivalent to GT1030 without video output and codec capabilities, and its main advantage is low power consumption, but the energy efficiency is not very high, and it has limited strengths compared to 1030.
If you really want to calculate energy efficiency, in fact, MX250 is definitely stronger than 1050M, after all, it is only 25W, and 1050M is already 75W, and the performance is not 3 times higher. The 1050 has less than twice as many stream processors as the 1030, so is it reasonable to have so much more power consumption?
Therefore, energy efficiency is really more important than performance, which directly determines how much electricity you use, how much heat you use, and how much performance.
The garbage guy dodged the 900M series abstract old yellow knife graphics card, dodged the MX series 3D accelerator card silicon slag scraps, but did not dodge the 10 series Samsung 14nm defense process, so the figure really has to study the specific level of the chip to pick up garbage, the main thing is to look at energy efficiency. Some of the group members will only look at the parameters and think that 960 is so garbage and not as good as 260 specifications, but in fact, it is not such simple things as specifications and absolute performance that determine whether the chip is good or not, but energy efficiency.
Therefore, the MX250 here is not as good as the 1050, which can only refer to absolute performance and no direct connection to the GPU, not energy efficiency.
However, the absolute performance is too low and it is a problem.,It's really difficult to use this thing to open Genshin Star Iron 2K.,It is recommended to directly reduce the score 1080P,Open FSR2 to play 0.8 or even 0.6 rendering to solve the GPU performance problem。
MX250 really can't beat the mobile phone now, but 888 is also a consignment, Samsung's 5nm process and Samsung's 14nm are the same as Wolong and phoenix. These two pits were trampled on by the same person, and the garbage guy could only see the old man's mobile phone in the subway.
888 is also sent in the mobile phone.,The level of this thing can only be said to look at the running ladder chart NB.,But if you really want to use it, it's better to get a Kirin 990.。
Again, absolute performance can only be obtained in an ideal state, and the actual performance release is an indicator of how much performance you can use when you usually use it, and the most critical indicator to determine the performance release under fixed conditions is the energy efficiency of the chip, whether it is a mobile phone or a notebook, it is impossible to infinitely pile power supply for heat dissipation, so if the energy efficiency is not good, nothing will work.
Snapdragon 888 energy efficiency is more specific, it can only be said that Huawei uses the DUV process under the premise of being sanctioned, and the energy efficiency of the Kirin 9000S with the worst physique is higher than that of Snapdragon 888, so there is no need to say what level this thing is. Standby will heat up, which is no longer a problem of process or not, it is completely a problem with the chip design. Don't be fooled by what the ZTE KPI on the Internet says "999 buy 888, I praise it when it is fried", in fact, 999 you buy a "brand new" inventory for several years is better than on the fish to see the foreign garbage or second-hand, now the mobile phone is in the price of 500 yuan Kirin 994 + Barong 5000 crawling all over the ground, the actual use of the designation is stronger than the fire dragon, so we can't see that the 888 pit now has the need to jump in. It is estimated that this group friend also bought it before (after looking at the model, the finch food is the previous machine).
By the way, this water friend is actually quite good, and he already knows the problem of the temperature wall. The temperature wall and power consumption wall are the two mountains that restrict the performance release of modern chip products. Unfortunately, this thing is not artificially set to card performance, but caused by objective conditions limiting the upper limit of the temperature and power consumption of the chip, so unlocking the temperature and power consumption cannot improve the performance infinitely, and finally it is necessary to improve the actual performance under the condition of fixed power supply and heat dissipation by improving energy efficiency.
And from the perspective of the actual response of the group friends in the face of hardware problems, it can't be regarded as a novice.,Including the operation of the thin and light book to play games and change the game book directly, it's no problem.,And it also mentioned the past to look at the ladder map.,So let's think Lao Tie still has basic hardware knowledge.。
In the face of practical problems, the only thing that may be lacking is the tools and software and the practical skills of picking up garbage, which is not much worse than the figure of the old brother, so we only need a little guidance to solve the problem quickly.
By the way, the tutorial on the use of MSI small aircraft seems to have been written before, but we don't know if it hasn't been written, so I don't know.
And the group friends later explained the reason why they had to have a notebook, that is, because they had to go abroad at the end of the year. So even if Jeopardy 0 doesn't go online this year, it's estimated that you won't be able to consider installing a desktop computer for a long time in the future. That's when a notebook is necessary.
We tried to carry a desktop computer out of the house, but it was not easy to eat, and in the end I still had to be honest with a notebook.
So it's still a bit useful to play games and run international servers.,Compared with the abstract and expensive international service of the national service, it's really the dragon and phoenix in the per capita person.,Even if you can't let the rich brother VIVO50 at least when you're online, you can also exercise the foreign language.。 At least I won't come to add your friends and have nothing to do to instill you with classic Internet rumors on the short video platform, as long as I see you online, I will come to reread the classic rumors with you online, I will really thank you.
So finally back to the beginning. Is it okay to buy a notebook on the PDD?,Personally, I think it's okay if the price difference is big enough.,Anyway, this thing is all global warranty.,It's the same wherever you buy it.。 Of course, as a garbage guy or that sentence,When you buy it directly, it's optimistic, and then it's not bad, that's the best,But buy a brand new thing, it's hard to be sure that it must be no problem,Although Lenovo Rescuer doesn't seem to have problems such as low-temperature tin motherboard, over-fried battery, bulging, black screen, heat dissipation, and cross-underworld design,But expect it to be not bad, it's not good to rely on brand effect alone,It's still necessary to implement specific products。
It is said that Dell's notebook is not a big problem.,But the garbage guy didn't know the problem of the Samsung defense process of the 10 series graphics card, so he finally stepped into the pit accurately.,Finally, I got a high-U low display without a separate display directly connected to the heat dissipation span of the five, directly to myself PTSD, I'd rather change the mobile workstation for the elderly than touch the game book again.,In fact, the main responsibility is not to check carefully before buying it.,Too much trust in acquaintances always think that acquaintances won't have pits.,As a result, the gold coins were blown up by Lao Deng in vain。
So it's still that sentence, it's really that if you can't eat and wear poor, you won't be poor, if you can't calculate it, you will be poor, if you have experience in avoiding pitfalls, welcome to post it in the comment area, let us become stronger together!
That's all, thank you, friends!
