For less than 1,600 yuan, I bought an “all-in-one desktop computer”

Before we begin, Xiaolei would like to ask everyone, are you familiar with specific educational hardware such as student computers?

About two years ago, during the years when the epidemic was more severe, due to the requirements of epidemic prevention and control, the demand for online teaching skyrocketed. In order to ensure that their children will not fall behind in schoolwork, many parents not only buy various online courses for their children, but even equip them with various electronic devices, including tablets, mobile phones, and computers. Various manufacturers are also entering the game at this time. .

Lenovo, a major hardware manufacturer, has also focused on this demand hotspot and launched a Lenovo Tianjiao 16 student all-in-one computer with a 16-inch 2K 60Hz anti-blue light touch screen, equipped with i5-1155G7 512GB SSD 16GB LPDDR4-4266 For memory, the initial price is actually set at 5,999 yuan. Even under the market environment at the time, the price of this product was quite outrageous.

I don’t know why now. This product is on clearance in a large number on Dongdong Duobao Island. It is almost in perfect condition out of the box. The price ranges from 1,600 to 1,800 yuan. This price is much cheaper than many Android student tablets today. Driven by cost-effectiveness and curiosity, Xiaolei bought it back just to see what the learning experience of this product is like. Of course, I also want to explore what new ways the Tianjiao 16, which is equipped with a Thunderbolt 4 interface, can play.

Appearance design: light green all-in-one machine, full of vitality and suitable for the occasion

After unpacking, the contents of Lenovo Tianjiao 16 include a tablet all-in-one machine, a docking station base with added interfaces, and There is a study lamp on the base, a large 65W Type-C power adapter and instructions.

Let’s take a look at the body first.

Tianjiao 16 all-in-one computer is actually assembled from three parts. The main body is the huge 16-inch Windows tablet in front of you. The front is a 16-inch screen with unequal width on all four sides. It has a 2K 60Hz screen and supports 10-point touch. Although the matte-processed screen is not transparent enough, it does effectively reduce reflections and theoretically is more eye-friendly.

The outside of the tablet is wrapped A ring of soft glue is used for protection, and the user can peel it off with bare hands.

There are only speakers and air outlets on the left side of the tablet, and no interfaces are seen.

The one on the right side of the tablet The buttons from top to bottom are: there is a power switch at the top; downwards are two Type-C interfaces, the upper one supports external video signal input, and the button next to it is for switching external input and internal output; the lower one is rare Thunderbolt 4 interface; at the bottom is the extremely advanced 3.5mm audio jack.

The actual measured weight of the flat panel part About 2.2kg, it is not a weight that ordinary people can pick up for daily use.

The base part is also made of plastic material. After inserting the host into the base, 4 USB Type-A interfaces (2 USB 3.0, 2 USB 2.0) and a Type-C power port can be expanded. The quality and quality of the interfaces that come out are relatively average.

The desk lamp is plugged into the base and supports up to 4 levels. Brightness adjustment, there are brightness addition and subtraction switches on the base. After opening, the default brightness is 2 levels, and the last brightness cannot be remembered.

The color temperature of the desk lamp itself The color gamut is pretty good, and it looks quite comfortable, but it only has one height and does not support angle adjustment. This lamp was probably designed for vertical screen scenarios, so it will leave a lot of space with the screen in landscape mode. It has a large space, and you can directly see the luminous part by raising your head slightly, which is still a bit dazzling.

Learning experience: Barely usable, but has many shortcomings

Since it is a student computer, let’s first talk about the learning experience of this machine.

Lenovo Tianjiao 16 has a built-in Tianjiao Academy system - in fact, it is a separate educational application. When the user starts the computer for the first time, he can choose whether to automatically enter the Tianjiao Academy or the Windows system every time he boots up. It is a design to prevent children from secretly playing on the computer.

After entering the Tianjiao system, open the famous teacher classroom, and the user can choose preschool, primary school , junior high school, high school and other age groups, covering the entire school age group from kindergarten to senior high school, making it convenient for students to obtain online courses for corresponding grades.

Considering that eight years after graduating from college, I had almost completely abandoned my conventional knowledge, I chose the freshman year of high school without hesitation.

After choosing your age , the machine will provide a study plan and teaching procedures covering a total of 8 subjects including Chinese, mathematics, English, physics, chemistry, history, geography, and biology. Xiaolei himself is a typical liberal arts student, so of course he first chose history to experience the entire teaching process.

After entering the details page, you can see that Tianjiao Classroom is based on each subject. It is not only equipped with synchronous video learning, but also provides users with after-class knowledge point videos, college entrance examination must-test points, and knowledge points. Consolidate training and other functions.

While learning each Before the content of a chapter, you can preview in advance through synchronized videos. After studying the content of each chapter, you can quickly lay a solid foundation through knowledge point consolidation and practice. You will also get detailed analysis of the answers in the wrong question book, as well as real questions from various places. The test paper can basically complete most of the chapter tests and knowledge consolidation.

Full set of learning process experience It may not have any special features, but the amount of educational resources is still sufficient.

The special feature of this machine is the second camera built into the desk lamp.

Judging from the videos of other users, after turning on the fingertip word search function, we only need to put the articles to be translated on the desktop, and then we can translate the content by drawing with our fingertips, and the content will be recognized The speed is quite fast.

However, this function cannot be activated on our Tianjiao 16 currently. According to user feedback from the App Store, Tianjiao Academy will have an issue where the fingertip word drawing function cannot be turned on after updating to version 1.0.3.27. We hope Lenovo can fix it as soon as possible.

Interestingly, Except for Lenovo's own fingertip translation function that works sometimes and sometimes doesn't work, there seems to be no second application on this machine that can call this camera. Even apps like Yuanfudao, which take photos and search questions, can't call this camera normally. The camera is really a bit outrageous.

In fact, if you observe carefully, you will find that the built-in functions of Tianjiao Academy are basically implemented by calling third-party APPs. For example, synchronous video is called by Geling, and knowledge point consolidation is called by It’s Afan’s question. Basically, users only need any set of ordinary computers to realize these teaching functions.

By the way, for For some parents who are concerned about their children's self-control, Tianjiao Academy also has a supporting parent application.

Without binding the parent client, Tianjiao Academy will impose strict restrictions on entertainment applications and web browsing. Unauthorized applications will be included in the control list. Even exiting the application and entering the Windows system desktop It requires parental consent.

As shown in the picture, Xiao Lei operates on the Windows desktop I installed Master Lu on Xiaodu tablet. After entering Tianjiao Academy, the application was immediately included in the prohibited list. Children can only use it with the permission of their parents.

Binding Lenovo After Tianjiao 16, users can check usage time, application usage records, and course usage footprints through Xiaodu on the mobile phone. They can even set the single usage duration, full-day usage duration, and disabled time period of Xiaodu smart learning tablets. Every move is under control.

It is worth mentioning that Tianjiao 16 does not have the AI ​​function that most current learning machines basically emphasize.

In Tianjiao Classroom, there are no functions such as AI correction of essays or AI explanation of questions similar to those promoted by similar products. It is basically the earliest set of designs among educational products. It depends on whether the children are willing to learn it. How can parents force me?

However, after starting the Windows system, we can actually apply it in Lenovo A series of AI applications such as AI writing assistant and AI painting can be downloaded from the store, which can be regarded as making up for some shortcomings in this area with the help of the capabilities of third-party applications.

Just doing this seems to be a bit contrary to the concept of a ready-to-use learning machine.

High playability: In addition to learning, is it unexpectedly fun?

After talking about Tianjiao 16 as a learning machine, let us explore the playability of this product.

Lenovo Tianjiao 16 is equipped with an 11th generation Core i5-1155G7 processor. This processor is basically a reskinned version of the i5-1135G7. It has a 10nm process technology, four cores and eight threads, and is equipped with the first Generation Intel iris Xe 80EU core display.

Actual measurement in CPU-Z, this i5-1155G7 single-core can reach 442.1 points, multi-core is 2483.9 points; under the CINEBENCH test standard, R20 multi-core 1299cb, single core 499cb, R23 multi-core 3392pts, Single core 1343pts. Although the single-core performance is acceptable, there may be more than 4 times the performance gap compared to the currently popular Core Ultra processor.

As for this Iris The Xe core display achieved a graphics score of 1117 points in the 3DMark Timespy test, which is about twice the performance of the current mainstream core display.

Although it was the standard configuration of thin and light notebooks three years ago, Lenovo Tianjiao 16 is still very suitable for office work today, and it still performs well in some medium-to-high-load office scenarios, such as using Photoshop to post-process the product photos that need to be used in the article (non-RAW images), or opening them at the same time It’s a good experience to draw materials from multiple web pages, write, etc.

Although the graphics performance of Iris Xe core display is average, it inherits the excellent video encoding and decoding capabilities of Intel core display. Lenovo Tianjiao 16 can not only smoothly play 8K@60fps and 4K@120fps local and online videos, but also It is also very efficient when editing and producing videos. If you have live streaming needs, this machine is just right as a streaming machine.

Not only that, the The machine also supports C port video input.

As long as you press the mode switch button above the C port, you can connect a device that supports C port output to the Tianjiao 16 and use it as an extended screen that supports touch functions. You can even connect a mobile phone or computer that supports USB 3.0 to achieve perfect picture output.

Finally, as a Taiwan’s educational hardware, Lenovo Tianjiao 16 is equipped with Thunderbolt 4 interface for the first time.

Even today, most manufacturers are still reluctant to spend this money. It can be said that 80% of the mainstream thin and light notebooks and gaming notebooks on the market are grateful to have a Thunderbolt 3 interface, and some even use USB 3.2. Gen1, or even USB 2.0 machines.

The existence of Thunderbolt 4 means that this product is qualified to be connected to an external graphics card dock.

Just in time, Xiaolei has a GPD G1 graphics card dock, connect it to Lenovo Tianjiao 16 with Thunderbolt 4 cable, and then install the AMD graphics card driver, we can start a pleasant journey.

GPD G1 Graphics Card Dock It has a built-in AMD RX7600 mobile graphics card, which can achieve performance close to RTX 4060 when using the Oculink interface. When connected to Tianjiao 16, 3DMark TS can reach 8991 points at best, with a performance loss of 10 %, close to the performance of the 130w RTX3060.

Actually ran a bit "Shadow of the Tomb Raider", without turning on DLSS and defaulting to 2560×1600 high image quality, the average number of frames in the game benchmark test when Tianjiao 16 is connected to an external GPD G1 is 50 fps, because the output screen needs to be rendered again by the core display. The reason is that the bottleneck when actually running the game is still quite large, basically only at the level of the mobile RTX 3050Ti.

#But as an experimental secondary aircraft on a whim, this experience can be considered exciting. Surprised.

Summary: Student computers are unreliable and may be suitable as secondary computers

As usual, the following is based on Lei Technology’s standard evaluation template for Lenovo Tianjiao 16 students Summary of the all-in-one machine:

Advantages:

1. Good screen quality;

2. Support C port screen input;

3. Equipped with Thunderbolt 4 interface;

Shortcomings:

1. Lack of content, education resources basically rely on third parties;

2. AI is very weak , lacks AI education function;

If I were to use one word to describe Lenovo Tianjiao 16, it should be "unique".

There are very few educational hardware using Windows system on the market today. This is a relatively rare product among them. The higher hardware performance and highly open system make this machine have far more advantages than ordinary education. Due to the scalability of the hardware, in theory, this device can have application scenarios suitable for students from preschool to college and out into society.

As far as learning experience is concerned, the performance of Lenovo Tianjiao 16 can only be said to be "mediocre". Although there are many teaching videos and test questions built into Tianjiao Academy, they are basically implemented by integrating third-party applications. Nowadays, similar products like to promote handwriting, question recognition and AI functions, and even the translation function is missing due to bugs. If it doesn't come out, it really doesn't have anything eye-catching, and it can't compete with learning machines, learning tablets, and learning mobile phones - no wonder it's on sale.

To Speaking of extended gameplay, Lenovo Tianjiao 16 is really a lot of fun. It supports a screen that rotates and lifts, four speakers with excellent quality, a total of 4A3C interface configuration, high expandability brought by Thunderbolt 4, and even supports video input function.

Considering that the current price of this product is only about 1,700 yuan, interested digital enthusiasts can buy it back, whether it is a live streaming machine or a Nintendo Switch C Whether it is an extended secondary screen or a creative tabletop on a computer desk, I personally think they both have a certain value.

But if you really want to buy it as an educational product for yourself or your children, then I suggest you think twice before doing so.
