Direct Answers

Frequently Asked Questions

Why does 24GB of RAM matter on the ROG Ally X compared to 16GB on Legion Go?

Both handhelds share system RAM between the CPU and GPU (VRAM). On a 16GB device, allocating 6GB to the GPU leaves only 10GB for Windows 11 and game assets, causing hitching in modern games. With 24GB on the Ally X, you can allocate 8GB to VRAM and still retain a full 16GB of system RAM.

Does the lack of VRR on the Legion Go make a visible difference?

Yes. When games drop below 60fps on the Legion Go, you will notice stuttering or screen tearing unless you lock the refresh rate. On the ROG Ally X, FreeSync Premium VRR dynamically matches the display refresh rate to the game framerate, making 45–55fps feel remarkably smooth.

Which one is easier to upgrade with a bigger SSD?

The Asus ROG Ally X is easier because it natively accommodates standard desktop M.2 2280 NVMe SSDs. The Lenovo Legion Go uses the rarer M.2 2242 form factor, which has fewer options and generally higher prices per terabyte.
