Silent keeps things as quiet as possible, while Performance ramps up the fans a bit more to allow higher boost clocks on your CPU and GPU. I was playing Elden Ring at 4K resolution with high settings, and it was running at about at 30–40FPS which is far from a bad result for this kind of hardware. On ROG laptops, you can once again do this right from Armoury Crate: when you open the app, look at the bottom left of the home window for all the fan profiles available to you. You can connect an external monitor along with a mouse and keyboard, and play games with much higher settings. This is an external GPU dock, meaning it lets you connect a much more powerful graphics card - up to an Nvidia GeForce RTX 4090 Laptop, in the latest model - and it also gives you a lot more ports. Of course, it's still a laptop processor with integrated graphics, but if you want a more serious desktop gaming experience, there's the Asus ROG XG Mobile.
There isn't a lot I can say about performance based on this short hands-on time, but this is pretty fast hardware. With a screen this small, you can play games at 720p and not notice a big difference, and with upscaling, I didn't see anything that looked subpar.
It was running at high settings and 720p resolution, with Radeon Super Resolution enabled to increase the sharpness. There weren't a ton of games for us to try at the show, but I did get to play Ghostrunner, a fairly intense and fast 2020 slasher, and it was all pretty smooth.
