The 7940H and 7940HS are two variants of AMD Ryzen processors, with the "H" version specifically intended for the China market and the "HS" version for the rest of the world. The key difference between the two lies in the inclusion of the Ryzen AI engine.
The Ryzen AI engine, also known as Windows Studio Effects, enables certain AI-based features and functionalities in supported applications, providing enhanced performance in tasks such as video editing, image processing, and content creation.
Based on your information, it appears that the 7940HS processor has the Ryzen AI engine enabled, allowing it to run Windows Studio Effects and leverage AI capabilities. On the other hand, the 7940H processor for the China market might not have the Ryzen AI engine enabled, which could be the reason why you can't see Windows Studio Effects on your laptop.
Even if the advertisement suggests that the 7940H has an AI engine inside, it might not be the same as the Ryzen AI engine found in the 7940HS, which is specifically designed to support AI-related features.
If you wish to utilize the AI capabilities of the Ryzen processor, you might consider verifying the specifications of your specific model or contacting the manufacturer for clarification. It's essential to ensure that the processor you have supports the specific AI engine or features you are looking for to enjoy the benefits of AI-powered tasks and applications.
