All Specs The latest AAA games require more graphics horsepower for an immersive experience than the typical ultraportable laptop can provide. Dedicated gamers will often buy a beefy gaming laptop that can run such titles to their satisfaction, or reserve gameplay for their desktop PCs at home. A third option is to connect an external GPU like the Asus ROG XG Mobile to an ultraportable laptop. The XG Mobile is one of the better external GPU (eGPU) concepts we’ve seen, but it’s still an imperfect and expensive solution, with the XG Mobile and bundled ROG Flow X13 laptop starting at $2,999 and offering decent but hardly noteworthy performance. Most gamers will be better off with sticking with a beefier gaming laptop.
