In the past two years, the word "AI" has been the absolute trend of the Internet, from various large language models and commercial AI assistants of Internet companies to the picture rendering and image generation of our consumers' daily games.
[Testing AI performance] is a huge challenge for the pen bar, and various chip giants claim to have "strong AI performance", and some even add AI suffixes to product models to prove their AI strength.
What exactly is an "AI PC", and what should we think of this type of product?
Let's use the following computers to conduct a test to briefly analyze:

But if you want to have a newer mold design, then this generation may not be quite suitable for you.
In 2024, mainstream chip manufacturers will launch solutions with AI performance and NPU units on mobile terminals, but before March this year, it is difficult to quantify the performance between them through a standard process, and the strength and weakness can only be passed on by word of mouth or by listening to the propaganda of manufacturers.
With the launch of the UL Procyon AI Image Generation Benchmark by ULSolutions (better known for its 3DMark), we can finally compare AI performance on a relatively fair track.
So we found laptops equipped with RTX 4060, 4070, 4080, and 4090 laptop GPUs, as well as Core Ultra 9 185H processors and Ryzen 7 8845H processors.
Ultra 9 and Ryzen 7 are both core graphics data, it can be seen that even the mainstream price of the RTX 4060 laptop GPU, compared with Intel's latest flagship Ultra 9 platform, the AI performance can still reach more than 9 times, and the RTX 4090 laptop GPU compared with the Ultra series processors, the AI can be improved by more than 22 times.
In tests of the more versatile ONNX Runtime engine, the RTX 4080 laptop GPU was accelerated using the ONNX framework, which was about 30% slower than using TensorRT, but still nearly 30 times stronger than the AMD Radeon 780M accelerated using the ONNX framework.
Since the birth of NVIDIA TensorCores, it has been able to significantly improve AI performance and provide epoch-making new features for PCs. RTX is currently supported in more than 500 AI apps and games. RTX 40 Series GPUs are the most popular AI GPUs on the market, bringing DLSS 3 Frame Generation, Ray Reconstruction, RTX Remix, and NVIDIA Broadcast denoising to Studio users. It has also provided NVIDIA ACE technology demo (AI NPC), ChatRTX technology demo (supporting personalized local document retrieval including Chinese large language model ChatGLM3-6B), TensorRT acceleration library and other AI applications. From the current perspective, GeForce RTX 40 Series GPUs have very strong AI performance, and they are not limited to AI painting and design, but can also provide convenience for AI applications in various industries such as games and large language models. The power of AI makes GeForce RTX 40 Series laptops essentially the only option for generative AI today.
At present, many thin and light laptops with insufficient computing power need to deploy AI in the "cloud", such as using some applications with relatively small computing power requirements, such as the "AI assistant" promoted by major brands, which can assist users in daily office and meetings.
The existence of GeForce RTX 40 series GPUs can achieve the high computing power that can only be achieved by real AI PCs - AI is "deployed locally and used completely offline", even when accessing top-secret data, it can ensure security and privacy, and there is no risk of data leakage.
