iPadCPU performance introduction :
iPad models cover a lot of content, and are presented directly in the form of pictures, making it more clear and intuitive.
Apple processor A series chip rankings are as follows, and the ranking data is comprehensively sorted by Geekbench single-core and multi-core running scores. Currently, the strongest comprehensive performance is the M1 chip , while the A15 Bionic ranks second, and the A12Z Bionic ranks third.
Based on the following CPU performance rankings and iPad configuration information, we can easily understand which rank we are in.
1. How to choose the iPad that suits you?
iPad series
Positioning: public, cost-effective, introductory, education
Scenario: watch online courses, take notes, entertainment, postgraduate entrance examinations, etc.
people: student party, partners who pursue cost-effectiveness
Recommended reasons
1. Student party is used to take postgraduate entrance examinations, study, take notes, and watch online courses. This one has the highest cost-effective
2. It has basically all the functions that the tablet should have, it is smooth and does not stutter, and the accessories are cheap
3. Initial design, keep the home key, and convenient use
iPad mini series
Positioning: Mainly portable, compact, small screen lovers
Scene: playing games, reading books, daily entertainment, etc.
Crowd: game party, reading party, and friends who watch TV series on a daily basis
Recommended reasons
1. No need to take notes, it is quite friendly for friends who like to play games, watch TV series, and read. In terms of handheld experience, it is also good compared to the other models. It is thin and easy to carry
iPad Air series
Positioning: Mainly mid-range, exquisite, thin and light
Scene: office, postgraduate entrance examination, study, entertainment, painting and other daily needs
Crowd: office party, student party, study party, entertainment party
Recommended reasons
1. The configuration is better than the iPad, the screen is larger than the mini, the price is cheaper than the Pro, and the performance is relatively balanced.
2. Take notes, draw, edit pictures, code words, watch online classes, etc. The overall experience of using Air will be much better than that of iPad.
ipad Pro
Positioning: high-end, flagship, performance
Scenario: handling high-performance professional functions: drawing, painting, video editing, etc.
people: professional users, pursuing high-performance experience, office party
html l0Recommended reason
1. The original color restore degree of the screen is very high, the picture quality is more delicate, the 11-inch has a maximum brightness of 600nit, the 12.9-inch uses mini-LED, and the peak brightness reaches 1600nit
3. .Absolute performance monster, dealing with professional work painting, editing, shooting, multi-tasks, etc., so easy (just the learning cost is high)
3. Equipped with a front-facing ultra-wide-angle camera, the selfie is great, but the people who shoot ultra-wide-angle are a bit exaggerated (you can tell if you try it~)
4. You need the best to buy anything, and you don’t lack budget partners, just buy
3. How should you choose various sizes? Although there are slight differences in screen sizes of new and old products in
iPad series, there is no big difference; you can check the comparison picture below for the size.
10~11 inches, suitable for ordinary users . If you like small sizes, choose pro12.9 inches for large sizes,
However, the iPad Pro12.9 screen is really not small, please choose carefully.
2, , , buy a new iPad or a second-hand iPad?
New or second-hand phones are your own wallet; if you don’t have enough money, you can skip this section and directly buy new high-end models; if you have a limited budget, you can consider a second-hand iPad and buy a more cost-effective iPad.
Because the new iPad is expensive, many users with underbudgets turn to second-hand iPads to meet their needs at the lowest price.
second-hand iPad covers a wide range, not only new models that have just been released, but also old models; an iPad has a service life of seven or eight years, and it is not recommended to buy models released 16 years ago.
4, , , how much memory can you buy in ?
memory determines how much you can store. If you are a heavy user (painting, photography, video production, etc.), it is recommended to choose 256G or above in the memory. If you just look at iQiyi and brush online classes, choose the 64G memory entry-level model.
5. Which second-hand iPad is chosen for different budgets?
Whether you are buying a new phone or a second-hand iPad, everything is a hooligan if you are not budgeted.
1000—2000 Yuan file : Optional iPad5, iPad6 and iPadmini4
CPU performance ranking: iPad6ipad5mini4
the above three models I recommend the iPad 6 generation, which not only has better performance, but also supports the first generation of Applepencil; if it is a daily online class, watching dramas, and reading e-books, this model is also enough for daily use.
2000-3000 yuan file: optional iPad8, iPad9; iPadAir3, iPadmini5
The above three models support first-generation pens, mainly in terms of performance distinction. iPad8, iPadAir3 and mini5 are all A12 processors ; iPad 9 is A13 processor.
Daily watching TV series, taking online classes, and taking notes, it is recommended to choose iPad Air3, iPad8 and iPad9; if you like a small screen, you can choose iPad mini5.
3000-4000 yuan file: optional iPadAir4, iPadPro 11-inch (18 models ) , ipadmini 6
CPU performance ranking: ipadmini 6iPadPro11-inch (18 models) ipadmini Air4
all support second-generation pens; for daily light work, painting, and design, choose iPadPro or iPadAir; if you only consider playing games, reading, and small-screen iPadmini.
4000 yuan or more: Optional iPad Pro 11 inch 20 models; iPad Pro 11 inch 21 models; iPad Air5
CPU performance ranking: iPad Air 5 iPad Pro 21 models ipadPro 20 models
0 There is nothing to introduce in this price range, buy it casually. If the budget of
is sufficient, you can consider Air5. Its appearance, configuration, screen and other aspects are better than iPad2021; if the budget is insufficient, iPad2021 and iPad2020 are also sufficient for daily use.
6. How to avoid pitfalls from ?
will share with you the routine of using second-hand iPads, avoid paying IQ tax during the purchase process, I wish you all to buy a good machine.
1. Determine the budget and understand the second-hand market price
First of all, we need to understand the reasonable prices in the second-hand market. Many merchants use the psychology of consumers to greed for cheapness to sell various problem machines at low prices, and they should be more careful when buying on a certain fish. You can check the approximate second-hand iPad prices at Aipaofan Mall. You must pay attention to machines that are far lower than the market conditions. For example, buying iPad 8 generation for 1,000 yuan is obviously not in line with the market.
2. Filter ID machine
Get what you get when you get what you pay for is the eternal truth. As long as you don’t greedy for small gains, you will most likely not be fooled. Because this kind of machine cannot log in to Apple ID, this commonly known as "ID" machine not only cannot download the APP normally, but also has the risk of being remotely locked.
3. display machine
. Machines like this are relatively cheaper and generally belong to engineering machines. Their performance is far less stable than retail machines. Due to the long-term charging for display, the actual situation is far less healthy than that of the appearance.
4. Capacity Expansion Machine
You must avoid the expansion machine routine, even if the merchant says it is so perfect. Therefore, in order to meet consumers' memory needs, some merchants will expand 32G to 128G or higher.
capacity expansion is similar to "cardiac surgery" on iPad. After a master with good skills is replaced, it may ensure that there will be no problems in a short period of time, but many masters are not in place in the technology, resulting in unstable performance and various problems in the heat storage.
5. Maintenance machine and renovation machine
The second-hand market is complicated by various problem machines, and this kind of machine novice cannot distinguish. If a machine that cannot be used with fingerprints and facial recognition cannot work properly, this kind of machine is likely to have been repaired and the selling price will be lower than the market price, and it will also be accompanied by many risks.
assists in discrimination through Aisi Assistant to see if Aisi tester is all green; if it is all green, it does not mean there is no problem, but once there is red, it means there must be a problem.
6. Change serial number model
change code machine as the name suggests has modified the serial number information, and the query model does not match the actual model or the model cannot be found. The main reason for the code changer of
is that there are many stolen machines in the market. The machine has an ID account that cannot be used. Therefore, JS will be activated through special means. The term in the line is called "circling activation lock". Bypassing the original activation lock by flashing the machine and re-entering the system. If the factory settings are restored, the activation lock will appear again, which means it cannot be used.
7. Common iPad test methods for ( second-hand , new machine general )
Here, we are organized to share some basic knowledge of machine testing for everyone to avoid losing money by buying second-hand garbage. iPad is better than iPhone . For novices, the difficulty of machine testing is mainly to distinguish between refurbishing and dismantling machines.
1. Basic information
1. Model
Find the "model" at "Settings-General-About Native Machine". The first two letters of "/" are the channel codes of the machine; CH is the national bank, ZP is the Hong Kong version; LL is the US version, etc.; can be used to refer to the introduction below for details.
model column first letter is M for normal retail machine ; N for official replacement machine ; official replacement means that during the warranty period, there is a problem with the original machine, and a new machine was replaced through the after-sales warranty on the official website. It is different from the original machine serial number, but the warranty inherits the original model.
model column first letter is F for official machine ; that is, the machine renovated through Apple's official website channel. The two most common markets in
are the Chinese version (China), Hong Kong version, American version, Japanese version, Malaysian and Australian version.
2. Capacity
Regarding the memory in this machine whose total capacity is iPad; check whether it is consistent with the memory information after checking the code.
FAQ: Capacitor expansion machine.
, for example, 32GB expands to 128GB; the expansion machine not only moves through the motherboard, but also has unstable performance and is extremely likely to lose data.
If you have a little experience, you can check whether the memory is in line with the code check tool.
3. Serial number check warranty
Enter the serial number information through the official channel to query the iPad warranty status.
FAQ: Modify the serial number.
An iPadmini2, the query serial number result is iPad4. This kind of machine has modified the serial number by surrounding the activation lock. If the serial number is inconsistent, it is very likely that there is a hidden ID. It is not recommended to start.
2. Function detection
1. Fingerprint/face function
Enter the system settings to find the fingerprint function. If you can successfully enter the fingerprint, it will be normal. After iPad Pro 2020, the model is face ID.
FAQ: Face or fingerprint is not available.
Since the fingerprint module and face ID correspond to the CPU on the motherboard, it cannot be used, which means it is a refurbished machine.
2. Charging function
plug in the charger and it shows that charging is normal.
FAQ: There is a foreign object in the charging interface, damping is relatively strong; replacement of the tail plug, etc.
3. WiFi
The machine can turn on the WiFi function normally, and the number of searched signals is not less than 70% of the normal value. If you can connect to WIFI normally, it means that the function is normal.
FAQ: Cannot search for WiFi or the WiFi signal is weak.
4. Camera
Open the camera, wipe the camera clean, take pictures against the solid color interface to see if it is normal; switch the video recording function, record the video to check whether the screen is normal; take 200 photos in a row to see if there is a middle section caused by the CPU problem.
Note: Both front and rear cameras must be detected.
FAQ: Taking photos with spots or watermarks (caused by dust or water stains entering the camera), generally does not affect use.
5. Key function
HOME key
Open any function or APP, press the Home key to return to the main interface normally, and the function is normal.
volume key
Press the volume +- key to check whether the volume gradient icon appears on the screen, and the icon changes with the button +-.
Power key
When the screen is on, press the button to lock the screen normally. When the screen is off, press the button to light up the screen, which means that the function is normal.
6. Touch function
Drag an icon and slide along the edge of the screen and around it. If it does not fall throughout the whole process, the touch is normal.
FAQ: Touch screen fails and there is a touch blind spot.
touch screen partially fails, resulting in unclickable; you need to experience it in depth for two days when you get the iPad, especially when playing touch screen games (thinking: Happy Elimination Le ). You can download Happy Elimination Le , and other games are also OK. Here is just a chestnut.
7. Voice memo or video
Open this software, then record an audio, and the playback sound is clear and normal, indicating that the microphone and speaker functions are normal.
3. Screen display
Newcomers do not understand iPads and cannot see that the aging color difference is displayed. This is normal, but there are obvious defects such as broken wires and leakage. I feel that it is necessary for everyone to introduce it, because this has a great impact on the screen.
Observe the screen under a pure white interface to see if there are bright backlights, broken wires, leakage, compression damage and picture-transparent conditions on the screen.
4. Maintenance issues

Aisi full green may not be without problems, Aisi piaohong must have problems, so finding a reliable purchasing channel is more important.
ISIS Assistant is difficult to read out the screen data, so it requires manual judgment. We pay more attention to the following details when checking the machine:
1. Is the camera position offset;
2. It is difficult for small merchants to create a dust-free environment by pressing the screen, check whether there is dust at the bottom of the screen;
3. Observe whether the black border is uniform on the white interface;
4. Is there obvious signs of prying the border.
The above articles cover a lot of information, all of which are practical information. After reading it, you will definitely have a deeper understanding of the iPad and have a deeper understanding of the skills of purchasing and testing second-hand iPads. If you don’t like it and collect it after reading it?
