Und ich muß es auch hier wieder erwähnen. Der Test zur Rechenleistung des X13 von Notebookcheck war fehlerhaft (siehe Kommentare dort). Eine falsche Aussage wird nicht besser, auch wenn man sie dauernd wiederholt.

Under load it's noisy as a vacuum cleaner. The hinges are very vulnerable - design fault not corrected from previous years. DIlbert kind of story.

Very good question. No, they didn't. Great specs, faulty design.

It is easy to verify if you check the picture uploaded by the reviewer from CPU-Z. To help you  /Affordable-laptop-with-AMD-Ryzen-5-APU-and-2K-display-for-395-Chuwi-CoreBook-X-review.1117292.0.html . Unfortunately there is a rule about hyperlinks so I cannot provide the whole link (literally just add notebookcheck.net)

Check L3 Cache, Codename and compare the processors.

If you want to dive deeper you can also find the that family and model also corresponds to 5500u but to keep it simple I only provided info from notebookcheck only.

I just want a ~10" foldable that mimics the form factor of the original Lenovo Yoga Book. Why, 10 years later, can we not have that?

It was only 4mm thick when opened. Foldable phones have hit this thickness, but for some reason laptops keep missing the mark. That, and we keep getting piles of 13" models that negate the portability proposition that foldables make possible - a 10" foldable gives you tons of space when completely unfolded with a keyboard accessory, and a compact easy-to-carry form.factor on the go.

The game supports terrorist so i don't want it even free
