Upgrade Ryzen 7 8845H processor to create three major experience advantages
For XiaoxinPro14 AI superbook 2024, the new performance experience brought by the hardware upgrade, as well as the resulting AI feature blessing, can be said to be the biggest attraction. After all, what new features the AMD Ryzen platform brings to this classic 14-inch portable notebook series will determine what the actual user experience is when they use it.
First, thanks to the NPU and Ryzen AI ecosystem support, laptops have localized AI application capabilities.
Second, the Radeon 780M GPU allows thin and light laptops to have good graphics performance.
Third, the Ryzen 7 8845H platform's high energy efficiency ratio brings better battery life, heat dissipation, and performance output capabilities, which provides an excellent unplugged mobile office experience for the Xiaoxin Pro14 AI Ultrabook 2024.
So in the next test part, we will mainly focus on these three aspects to see how the performance of Xiaoxin Pro14 AI Ultrabook 2024 is?
Accelerate ideas with AI
First of all, let's take a look at the highlight of this update - localized AI application capabilities.
The Ryzen 7 8845H processor equipped with the Xiaoxin Pro14 AI Ultrabook 2024 is equipped with an NPU suitable for low-power AI computing, and the CPU and GPU also support corresponding AI acceleration capabilities, which can bring users a safe and efficient localized AI application experience. We first evaluated the Float16 floating-point computing power of the Radeon 780M GPU of the Ryzen 7 8845H processor through UL Procyon, and scored 241 points.
Let's take a look at how it performs in AI applications through actual experience. The AI large model container used here is Amuse V1.3 version, and the test model mainly uses the popular LCM Dreamshaper v7-Olive.
512 × 512 resolution, only one prompt word, and 10 iteration steps, how fast can the image be generated?
Through the actual test, it can be seen that it took 7.74 seconds to complete the basic Wensheng map task, and the effect is quite good.
Of course, in our daily applications, we definitely hope that AI can help us make more detailed pictures, instead of low-resolution and relatively simple pictures like 512 × 512. So let's turn up the parameters and provide detailed prompt words and counter-prompt words to see how efficient the Xiaoxin Pro14 AI Ultrabook 2024 and Ryzen platform are?
We tried to generate a picture with a resolution of 1024×768, 20 iteration steps, and detailed prompts and counterprompts, and the overall time was 70.88 seconds. It has to be said that the improvement in efficiency after integrating AI into creative applications is amazing.
In addition to the Wensheng diagram, we can also create with the help of the painting sketch. On the left side below is the line drawing of the author with the mouse, it can be seen that this level has not reached the level of kindergarten children's painting, but with the help of some prompt words and counter-prompt words, the final generated picture has reached the level of junior high school and high school students, right? At the same time, the overall time is only 53.84 seconds, which is very efficient.
· AI captures the game's superpower moments
In addition to AIGC-related applications, the NPU of the Ryzen processor platform also has some AI applications that can be directly deployed on it. NPU is a low-power AI computing module, and the most suitable tasks for it are continuous AI computing tasks in the background. For example, during an online meeting, the background blur of the camera and the continuous noise reduction of the microphone are very suitable for NPU, which can carry tasks in a low-power state, which is more energy-efficient than putting it on the CPU and GPU.
Like the application "Game Plus", which is used more by gamers, it has taken the lead in adding support for Ryzen AI NPU, and has integrated all the AI functions that support NPU into the "2 Ha ai" page, including "Super Moment", "AI Game Coach", "Peripheral Aura Light Control" and other functions, check the AMD Ryzen AI NPU mode under the corresponding page, and turn on the enable switch to use.
In many popular games such as Valorant, PUBG, and APEX, the function of AI is mainly to help players automatically capture wonderful shots during gameplay and quickly produce "super moments", which is also a type of AI application that is persistent in the background, which is very suitable for NPU to execute.
Once you're in the Super Hour, you'll see that the AI recognition mode has a dedicated AMD Ryzen AI NPU mode, and players can set it up as needed to better capture the best shots during gameplay.
The "Game Plus" has also added the function of "AI Game Coach", although it has not been turned on yet, but it also supports the exclusive AMD Ryzen AI NPU mode.
As you can see from the GIF below, during the game, Game Plus can also monitor the working status of the NPU of the Ryzen platform in real time. Using AI technology to capture the wonderful picture video of the player while playing in real time, it is really suitable for some friends who want to post their wonderful operations to the media platform.
Better DingTalk online meeting experience
In addition to gaming, online meetings are also an important area for Ryzen AI to exert its strengths. For example, DingTalk is commonly used by enterprise users. When we start an online meeting, the background clutter, the movement of people, etc., can lead to a bad experience. With the help of AI technology, the online meeting experience can be improved as much as possible.
I used XiaoxinPro14 AI superbook 2024 to experience an AI-blessed online meeting, which can use AI to achieve portrait centering, that is, to track the position of the person in real time, so that I am always in the middle of the picture, so I no longer have to deliberately stay motionless and sit in a sitting position during a meeting. In addition, it can also achieve video noise reduction and adaptive brightness adjustment of ambient light, so that the video picture is always in a "good-looking" state.
And if you're in a bad environment and don't look good during the meeting, you can also use virtual backgrounds and beautification features to improve it.
It is worth mentioning that DingTalk is now integrated with AIGC's background image generation function, which only needs to describe the desired scene with text, and the corresponding background image will be automatically generated, and the effect will be significantly improved after replacement.
Localized AI large language assistant
In addition, AMD has also developed a localized AI assistant, the Ryzen AI Assistant. It can complete the deployment of large language model AI applications on the AI PC side, which greatly reduces the application threshold. This AI assistant is developed based on the AMD Ryzen 8000 series AI PC platform, and currently integrates five large language models: Tongyi Qianwen, Baichuan, ChatGLM3, CodeGeeX2 and Bian Que, which can realize Q&A, dialogue, copywriting, programming, medical consultation, etc., greatly improving the practical value of AI PCs.
In some daily Q&A and copywriting applications, it can be completed through Tongyi Qianwen, Baichuan, and ChatGLM3, for example, I tried to ask a question like "Use AMD Ryzen 7 7800X3D as the main accessory to configure an 8000 yuan desktop", and the large model quickly gave the answer.
Tongyi Qianwen is relatively more rigorous in its answers, and some places that are prone to errors, such as the selection of motherboard interfaces, Tongyi Qianwen also gave accurate answers.
If you ask ChatGLM3-6B the same question, you can see that the style of the answer is unconventional, clear at a glance, and the generation speed is faster.
In addition, if you check the workload of the CPU and GPU through the task manager, you can see that the CPU is full, and the GPU workload exceeds 50%, and the overall performance utilization rate is very high.
In addition, for people like me who don't know how to program, some of the more explicit programming directions can also be easily achieved through large models. For example, I asked CodeGeeX2-6B to help me implement a simple greedy algorithm in java, which can also give answers very quickly.
In addition, for example, if you let it implement the Fibonacci sequence in Python, you will be able to complete the task locally very quickly.
More AI application blessings
In fact, the application of Ryzen AI is not limited to the scope of what is presented today. In some professional fields and vertical fields, Ryzen AI can also bring a good experience.
For example, for professional VFX users, Ryzen AI can now support Nero Motion Tracker AI video editing, which provides AI automatic facial recognition and tracking with the help of motion tracking plug-ins, eliminating the need for time-consuming and laborious manual frame-by-frame editing.
Another example is the veteran AI software Topaz, which is also supported by the Ryzen platform at the first time. Expanded image, video noise reduction, cutout, color restoration, detail restoration, and more can all get a better experience and higher efficiency from the Ryzen platform.
In addition, the Ryzen platform also supports the AI functions of Adobe Premiere Pro, Lightroom, and Photoshop, bringing users a smooth, stable, and efficient application experience in AI video editing and AI image editing.
It has to be said that AI is penetrating into all aspects of our lives and work, and the Ryzen platform and the NPU supported by Ryzen AI technology enable these AI applications to bring better efficiency and experience to users.
