News hardware Asus ROG Flow Z13: the Windows tablet that has nothing to envy to a gaming PC
Recently released on the market, the Asus ROG Flow Z13 is quite simply the most powerful Windows tablet on the market: basic, it allows you to play recent games in good conditions and to work ultra efficiently. But the magic really happens when you plug it into the ROG XG Mobile, a box that turns this two-in-one into a super-powerful gaming PC. A concept for the moment expensive, but which frankly seduced us.
Asus ROG inaugurated its “‘Flow” range last year, including the X13, a 13-inch ultraportable PC to take anywhere and equipped with powerful components. A few months later, we welcome the Flow Z13, which this time is a “two-in-one” PC, i.e. a Windows 11 tablet equipped with a detachable keyboard and a kickstand (an identical concept to the Surface from Microsoft). The 13.4-inch screen goes up to 1920×1200 pixels and displays a refresh rate of 120 Hz. The panel is of course touch-sensitive for versatile use.
ROG Flow Z13: the most powerful Windows tablet on the market
If you buy the ROG Flow Z13 “alone”, you will have access to a powerful product, capable of cashing in greedy games, with however some limitations. The processor is thus an Intel Core i7-12700H and the graphics card a GeForce RTX 3050 (4 GB). The kind of configuration that will allow you to play in 1080p with a “medium” or even “high” level of detail on certain titles. But difficult to launch a Cyberpunk 2077 with the ray-tracing at the maximum, for example, you hardly fall under 20 FPS. And that’s where the ROG XG Mobile case comes in.

ROG XG Mobile: the magic box that boosts your PC/tablet
The ROG XG Mobile comes as a box with a single cable, which connects to the Flow Z13 via a proprietary port. It also incorporates ultra-complete connectivity: several USB ports, an HDMI port, a DisplayPort, an Ethernet socket… The idea is to take advantage of an “all-in-one” format where you can connect your laptop to a a box, itself connected to a screen, a mouse and a keyboard. Your tablet then becomes a “fixed” PC with incomparable power.

Because what we did not specify is that the XG Mobile also includes a choice of a GeForce RTX 3070, 3080 or a Radeon RX 6850M XT. The power boost compared to the “base” RTX 3050 is impressive: while Cyberpunk 2077 will struggle to run with ray-tracing on the 3050, you will largely benefit from 50 FPS and more on the 3080 of the case. And all this, remember, by plugging in a single cable.
A high price, but a concept that hits the mark
The concept of the ROG Flow Z13 and the XG Mobile case is frankly attractive, with this idea that you can enjoy a laptop PC every day, at work or on the go, then a high-end gaming station once returned home. But all this has a cost: the Flow Z13 with its 3050 costs around €2000 and the XG Mobile box, with an RTX 3080, goes up to around €1500. We also regret the few products currently compatible with the XG Mobile.
Anyway, if you want to know more, do not hesitate to consult our complete test of the ROG Flow Z13, but also that of the ROG Flow X13 and the XG Mobile case.
