As AI sets off a technological wave around the world and profoundly changes all walks of life, the combination of AI and hardware is now becoming the most important development trend in the technology industry. In this context, the concept of AI PC emerged.

The so-called AI PC means that AI technology is deployed on PC through cloud and terminal side collaboration, thereby fundamentally changing the PC usage experience and greatly releasing people's productivity and creativity.

Speaking of AI PC, this concept was first formally proposed by Intel CEO Pat Gelsinger in September last year, and Intel has actually started working hard to introduce AI on PCs very early.

On December 15 last year, Intel officially released the Core Ultra processor based on the new Meteor Lake architecture in China. One of the most important highlights of this processor is the introduction of Al into client PCs , and integrates an independent NPU unit into the Meteor Lake processor architecture, bringing independent low-power AI acceleration capabilities.

There are already many AI PC products equipped with Intel Core Ultra processors on the market. As it happens, this site recently got a brand new Dell Inspiron 14Plus 7440 AI PC thin and light notebook, let us pass the evaluation today to see what kind of actual experience it has with the blessing of AI.

1. Appearance design

Let’s look at the appearance first. Dell Inspiron 14Plus adopts the new Echo Design design language, and the whole machine looks relatively rounded and has smooth lines. The color scheme of glacier blue is very refreshing and has a refreshing feeling, which is quite healing.

Side A of the notebook is very simple, with only a classic Dell logo. This is also the design of Dell notebooks that has been popular for a long time.

The line of sight comes to side B. Here is a 14-inch 2.8K resolution screen. The borders on both sides of the screen are narrower and the top is slightly wider. There are cameras and sensors. microphone.

The overall design of the C-side of Dell Inspiron 14Plus is actually a micro-curved surface with subtle arcs, not a flat plane, so When using it, the wrist resting on the C surface will feel full and comfortable. The keyboard has a sunken island design, and the touchpad area is large enough. Putting aside the various labels and stickers here, the design of the C side is actually very simple.

The D side of the notebook has conventional screw holes, cooling air outlets and foot pads. The D side has a rounded slope design around it. , thus making the notebook visually thinner.

At the same time, the use of various soft curves in the fuselage also gives Dell Inspiron 14Plus a very comfortable feel when in use. It can be said to be both good-looking and easy to use.

2. AI function experience

We said before that the important upgrade of Intel Ultra processor is to provide a new AI experience through CPU GPU NPU The three integrated AI engines provide powerful AI acceleration capabilities for PCs equipped with the platform, enabling AI to generate images in seconds, and large language models with up to 20 billion parameters to run normally without the Internet.

Looking specifically at this Dell Inspiron 14Plus, it is equipped with the Intel Core Ultra 7 155H processor. This processor has an architecture of 6 performance cores, 8 energy efficiency cores, and 2 low-power energy efficiency cores, 22 threads, and has 24MB. Level 3 cache, turbo frequency up to 4.8GHz, TDP 28W. The GPU is integrated with Ruixuan Arc integrated graphics card, with a core frequency of 800MHz, a 2x performance improvement, and supports 8K 10-bit HDR and AV1 codec.

The integrated NPU unit contains 2 neural computing engines, which can better support content including generative AI, computer vision, image enhancement and collaborative AI. . When working, this NPU is not a single island architecture. Both the CPU and GPU can cooperate to perform AI operations. Different AI units will be used to cope with different scenarios and coordinate with each other. As a result, its overall energy consumption ratio is higher than that of the previous generation. It can be increased by up to 8 times.

In order to test the AI ​​performance of Dell Inspiron 14Plus, this site installed Intel's AIGC Assistant demo version, which includes large language model and Stable Diffusion-LCM. The installation process is not complicated. After the installation is completed, it is deployed on the computer in the form of software.

Open the AIGC assistant demo version. The first is the functional interface of the large language model. Three models are provided here for switching. The editor uses the Baichuan2 7 billion parameter model. carry out testing.

Under the optimization of the Intel Ultra 7 155H processor, this large language model can run smoothly locally, so the editor disconnected the Inspiron 14Plus from the network during the test.

The editor first asks a common human question: "My friend wants to borrow 10,000 yuan from me, but I have been short of money recently. How should I decline him?" Regarding this question, the AIGC assistant answered it in seconds. Basically, the answer came out as soon as the question was sent, which was very fast.

At the same time, when the answer is generated, you can see that the GPU usage of the Intel Ultra 7 155H processor has increased to more than 50%, and the CPU usage has reached a maximum of 42%, which shows that it is indeed is run locally.

Then the editor asked a slightly more complicated question and asked him to help write an opening statement for the company’s welcome party. The AIGC assistant also wrote one very quickly, and Basically it can be used directly.

Then, the editor asked him to write a recruitment copy for Android programmers, giving multiple qualifications. The AIGC assistant also wrote very well this time, not only writing all the conditions It’s in the copywriting, and it’s written very quickly. It only takes ten seconds from sending the request to writing the copy. If the editor writes it by himself, it will probably take half an hour. The productivity and creativity of AI PC are evident.

Finally, the editor asked him to draw up an activity outline for the company’s product exchange meeting. Running the AIGC assistant demo version on Inspiron 14Plus was as fast, accurate, and stable as ever, and the generated The outline can be used after modification according to the actual situation.

In addition to the large language model, the Intel AIGC Assistant demo version also has the function of a drawing assistant, which is the Stable Diffusion-LCM model, which can assist us in image generation.

During the test, the editor first asked him to draw a cat. As soon as the request was sent, it generated 4 cat pictures in almost 2 seconds. This speed really shocked the editor. .

And when generating these 4 pictures, the Intel Ultra 7 155H processor CPU and GPU performance usage can reach 20%, there is usage, but not high, it can be seen that Intel The AI ​​performance of the Ultra 7 155H processor is not fully utilized.

Then the editor asked it to generate a slightly more complicated one, "a dog with black ears". The drawing assistant also quickly generated 4 pictures, and the dog The ears are all black.

Then the editor adds a little more complexity and lets it draw "a rainbow appears after it rains in the city". The drawing assistant's generation speed is still very fast, still about 2 seconds, and the generated pictures are very accurate and stunning. Use It is very suitable for making illustrations, materials, etc., which greatly saves the time of art workers.

The above tests were all conducted with the notebook connected to the power supply. Then the editor disconnected the power supply of Inspiron 14Plus and used only battery power. We tested the language model and drawing assistant, and the experience is almost the same as connecting to the power supply. Whether it is answering questions or generating pictures, it is still fast and accurate. Therefore, if you are on a business trip or working outdoors and cannot connect to a power source, you can smoothly use the power of AI large models to speed up your work.

Through testing the Intel AIGC Assistant demo version, we can see that with the support of Intel Ultra 7 155H processor, Dell Inspiron 14Plus does have strong terminal-side AI capabilities, running locally A big shock to the editor is that the large AI model is "fast" and "smooth". Whether it is generating copy or pictures, it can be done in 1-2 seconds, and it will not be affected even if the laptop is not plugged in. For those who need to create copy , picture creation friends, this is simply a great liberation of productivity.

In addition to Intel's AIGC assistant, this site has also tested other AI application scenarios, such as "Cut Screen" that short video workers may often use, Core Ultra The series has optimized the AI ​​cutout function of clipping.

When we cut videos, we may often need to extract certain elements from the screen. "Cut Screen" also provides a cutout function, but using this function in the past took up a lot of CPU performance, and It also takes a long time to complete the cutout. For example, this site uses the CPU of the Ultra 7 155H processor to perform AI cutout on a video in "Cut Screening". It takes about 2 minutes and 30 seconds. During this process , the CPU performance resource usage reaches more than 75%. This is based on the relatively high CPU performance of the Ultra 7 155H processor.

However, when the editor switches the "AI Keying" function to the NPU of the Ultra 7 155H processor. The keying speed has been significantly increased. It only takes about 1 minute and 24 seconds to key out the same character in the same video, and the keying effect is also very good. During the cutout process, the editor opened the Windows Task Manager and saw that the NPU load reached about 95%, and the acceleration effect was obvious.

In addition to "Cut Screen", IT also tested the live broadcast software XSplit. This software can be used for live broadcast and video conference recording. It is also a relatively high-frequency scenario in daily office work. In Intel Ultra With the AI ​​capabilities of the 7 155H processor, functions such as virtual camera smart keying and background replacement can be accelerated in software functions to achieve better performance and power consumption.

In the actual test, this site selected NPU as the rendering processor to test the front camera video portrait cutout, background replacement, blur effects and other functions. As you can see, the implementation These functions can keep the resource load of the NPU at about 35%-40%, and the actual experience can be very smooth.

It can be seen that with the assistance of the AI ​​capabilities of Intel Ultra 7 155H processor, Dell Inspiron 14Plus has indeed become a smarter and more productive AI than ever before PC, whether for office or creation, I believe it can bring you great convenience.
