Diddy 13in laptops are all well and good for taking on the road, but their compact shape and super svelte innards rarely leave much room for powerful gaming components. Indeed, the best graphics chip you'll often find on 'gaming' laptops like these is the humble Nvidia GeForce GTX 1650 GPU, as we saw on Razer's Blade Stealth 13 at the end of last year. It's the Max-Q version of this entry-level graphics chip that sits at the heart of the new Asus ROG Flow X13 as well, providing a decent 1080p gaming experience as long as you're prepared to make do with playing at Low to Medium quality settings. On the Blade Stealth 13, it was a decent trade-off considering the laptop's tiny form factor. The Asus ROG Flow X13, however, has a rather nifty secret weapon that turns this pint-sized gaming laptop into an RTX 3080 powerhouse. Enter the Asus ROG XG Mobile eGPU.
