Qitian A970 experience review, one machine with multiple functions, beautiful and smart

Everything nowadays requires efficiency, especially at work. So if a worker wants to do his job well, he must first sharpen his tools. Efficiently deploying a set of useful office equipment has become the prerequisite for everything.

In the past few days, I got a Lenovo Qitian A970 all-in-one computer specially designed for commercial scenarios. Today I would like to share my experience with you. If you happen to have relevant needs, I hope it can be helpful to you.

1. Appearance

Let’s take a look at the appearance first. Qitian A970 uses a 23.8-inch FHD screen with narrow borders on three sides. The visual effect after turning on the screen with narrow borders is still very good, and the sense of immersion is full. There is a 5-megapixel camera and dual digital array microphones on the top. This screen achieves a high refresh rate of 100Hz, a high contrast ratio of 1300:1 and an sRGB color gamut of 99%, and is equipped with hardware-level low blue light. Use i1Display Plus to compare Qitian A970 The screen color gamut was actually measured, and it can be seen that the color gamut coverage reached 96.3% sRGB. I also used UFO test to test the refresh rate of this screen. It has a proper 100Hz refresh rate, which is perfect for everyone. These display configurations can meet the needs for daily office use. A higher refresh rate will make the system animation look smoother and smoother, improving the daily use experience. Qitian A970 has also passed the dual certification of low blue light and flicker-free by TÜV Rheinland. For workers who have to work in front of a screen every day, this screen is definitely good news for your eyes. Looking to the side, you can see that the thickness of the screen is also well controlled, only 13.8mm. Although all-in-one computers are not like notebooks and require portability, as a fixed product, all-in-one computers are still more important in terms of aesthetics. With a thin and simple body, they can be placed in your own office. On the table, or placed at the service window to face outsiders, it can greatly enhance the look and feel. ‎After looking at the screen, let’s take a look at the base part. The overall design of the stand area is business-like and simple. The flat base can be used to place things on a daily basis without sacrificing desktop space. In addition, the stand area is also equipped with a pair of Harman Kardon speakers that support Dolby sound effects. The flat base part can also be optionally equipped with a wireless charging function to charge mobile phones and reduce one more wire on the desktop.

2. Expandability

For offices, the importance of expansibility is self-evident. Good expansibility can sometimes save time and improve efficiency significantly. The back of Qitian A970 is equipped with 1 USB3.2 Gen2 interface, 2 USB2.0 interfaces, an RJ45 network port, an HDMI OUT 2.1 TMDS (4K*60Hz) interface and an HDMI IN 1.4 interface. That’s not all. There is also a 3.5mm audio interface and a USB Type-C 3.2 Gen2 interface that supports fast charging on the side of the fuselage. Considering that the daily use frequency of these two interfaces is relatively high, High, so it is more reasonable to place it on the side. The other side of the fuselage is the physical camera switch key and power key. We will discuss this part in detail later. It is worth mentioning that the two HDMI interfaces on Qitian A970 are one for input and one for output. In other words, if necessary, this all-in-one machine can be used as a monitor to connect to other notebooks. Connect other external monitors to form a dual screen to improve productivity. Flexible usage scenarios can save enterprises a lot of procurement costs. When the host is updated, it can continue to be used as an external monitor. It can be said that one machine has multiple uses, greatly extending the service life.

3. Noise performance

During the past few days of use, my colleagues and I have noticed that Qitian A970 is very quiet when running, even under heavy loads. In the scene, there is no noise from the fan as expected. In order to quantify the silent performance of Qitian A970, we decided to conduct actual measurements of its noise under different operating conditions. One feature that needs to be mentioned before the actual measurement is the ICE6.0 intelligent temperature control engine of Qitian A970. You can quickly adjust the operating mode through the Fn Q key. With this function, positions with different performance requirements in the enterprise can be flexibly adjusted according to actual needs. For users with high performance requirements, adjust to performance mode for better performance release; users who work lightly can adjust to silent mode for quieter operation; users with changing office environments can set it to the best experience mode, and the system Automatically balance noise and performance. We tested the noise in the best experience mode and performance mode respectively. It can be seen that during actual operation, in the performance mode, the operating noise of the whole machine does not exceed 26dB. In the best experience mode, the operating noise of the whole machine does not exceed 26dB. , no more than 22dB, and the quietest silent mode is not unexpected by us, but the ambient background sound of Zhijia’s shooting room in the quietest situation is about 18dB, so it is certain that Qitian A970 in silent mode The operating noise must be less than this value. In fact, in actual use, even in performance mode, it is difficult to notice the sound of the fan unless you deliberately put your ear close to the air duct and listen carefully. This excellent silent performance may not be obvious to individual users. After all, there are usually only one or two desktop computers at home, and they may not run around the clock. It does not matter if the sound is louder or softer. But for enterprise users who often deploy dozens, dozens or even hundreds of devices in batches and need to run around the clock, the noise impact cannot be ignored. Imagine dozens of performance monsters equipped with 800W power supplies, with fans spinning wildly in the office area. It is also a kind of torture for people working there. Qitian A970's flexible and switchable ICE6.0 intelligent temperature control engine can achieve a balance between noise and performance, creating a comfortable office environment with as little noise as possible for workers.

4. Performance Measurement

Qitian A970 can choose Intel® Core™ Processor U300 and i5-13420H, i7-13620H standard voltage processor, standard dual-channel 16G DDR5-5200MHz memory, up to 1TB M.2 SSD, 90W power supply, if the base wireless charging function is optional, a 135W power supply is provided. The one I got is equipped with i7-13620H, 1TB SSD, and 90W power supply. I conducted some actual measurements in performance mode. In the CPU-Z test, the single-core score was 784.1 points and the multi-core score was 5782.5 points. This performance is sufficient for office use. In the 3DMark CPU Profile test, the single-threaded score was 1022 points, the dual-threaded score was 1991 points, and the maximum thread score was 5620 points. In the PCMark benchmark test designed for daily office scenarios, Qitian A970 scored 5838 points, which is sufficient for daily office use. In the CrossMark test, which is geared towards office scenarios, Qitian A970 scored 1680 points, which is no problem for daily office use. Some friends’ daily work may also involve light processing of images and videos. They also used 3DMark to conduct the Time Spy test, and the CPU score was 9051 points. In the CINEBENCH R23 test, the single-core score was 1796 points and the multi-core score was 12162 points; in the CINEBENCH R24 test, the single-core score was 105 and the multi-core score was 630 points. For some light daily tasks Image processing and video editing, Qitian A970 is also capable. In terms of rendering capabilities, Vray was used to conduct a CPU rendering test and scored 12875 points. In terms of system stability, we conducted a 20-minute CPU single bake on Qitian A970. The final CPU core temperature was 77°C, the power consumption was 41.5W, and the main frequency was stable at 3.99GHz. The performance The release strategy is conservative, but considering its office attributes that suppress noise, such a power consumption strategy is understandable.

5. Lightning startup

In addition to being quiet, another deep impression on me is that Qitian A970 is fast. It not only runs fast, but also boots up faster. To be honest, after pressing the button in the morning The speed at which the power button entered the desktop made me think that I had clicked not to shut down but to sleep the day before. This machine supports Thunder boot, which eliminates the time that a conventional computer needs to wait to enter the settings and boot menu. After the BIOS is initialized, it can directly fast forward to the SSD reading system. This change makes booting up as fast as waking up from sleep in the past.

6. Meeting Scenarios

In daily work, video conferencing must be a scene that gives many people a headache. I believe that many friends who use desktop computers are conducting video conferencing. Every time, I have experienced one or another embarrassing scene: either the microphone has no sound, or the camera has no picture, or the speaker cannot be heard clearly... You never know where the next pitfall will be that will prevent you from successfully conducting a meeting. As for video conferencing on Qitian A970, thanks to its integration, it can even be said to have an experience comparable to that of a mobile phone. You only need to turn on the camera switch and answer the call, and this The position of the camera switch must also be praised. In the past, the physical camera baffle of many computers was on the top camera part. When opening and closing, you need to reach out a lot, and it is easy to touch and dirty the camera. Put it on the side of the stand, and the switch is much more convenient. And unlike mobile phones that require one hand to hold and notebooks that have a strange upward angle, the Qitian A970 is normally placed at just the right height, slightly higher than the forehead, and everything is so natural and comfortable. In terms of audio, Qitian A970 uses deep neural network technology (DNN) to filter near-end and far-end noise. Speaking human words is intelligent noise reduction through AI technology. Whether it is the noise around you when you are talking or the environmental noise when the other party is talking, it can automatically identify and filter it, making the voice clearer. When this noise reduction effect is actually used, it is indeed It can be clearly felt. In short, the integrated design allows each component to perform its duties and operate stably, and the blessing of AI also greatly improves the effect of the meeting.

Summary

As a post-95s generation, I have experienced the iteration of the phone product from landlines, feature phones, and now smartphones with performance comparable to computers. We all know that for technology products, integration and intelligence must be the direction of future development. Qitian A970 allows us to see a new integrated, intelligent and beautiful solution for commercial computers, making it more convenient for enterprises to deploy. The simple business appearance design can be used whether it is placed in the office area, corporate front desk or In the school electronic classroom, the image of the company or school can be improved a lot. If you happen to have such needs, you might as well consider this machine. I believe it will definitely become a good office assistant for you.
