Modder Creates Gaming Handheld with RTX 4090 Laptop GPU and Intel i9-14900HX Featuring a 12.5-Inch 4K Display and 175W Mobile GPU

Man, so Qingchen DIY over in China went and did something pretty wild. I stumbled upon this on Bilibili, and honestly, I can’t stop thinking about it. Picture this: a 12.5-inch gaming handheld with a 4K screen. Yeah, you heard right. Dude slapped in an Intel Core i9-14900HX CPU and topped it off with an Nvidia GeForce RTX 4090 Laptop GPU. Seriously, who even does that?

AMD’s been running the show with their teeny-weeny gaming gadgets like the Asus ROG Ally X and Steam Deck OLED, packing them with their jazzy desktop processors. I mean, Intel’s had a go with MSI’s Lunar Lake, but honestly, nothing screams adventure like this insane Intel/Nvidia mash-up. Maybe Qingchen just wanted to see if Red and Green could party together in this market. Or I’m just overthinking it.

Apparently, the modder molded this handheld from a Tongfang chassis. Sounds fancy, right? And, weirdly enough, you probably know Tongfang more than you realize; they’re secretly the brains behind some big-name Western brands like PC Specialist and XMG. Go figure.

Packed under the hood are two laptop beasts: that i9 CPU with its whole entourage of cores, getting a lift from the RTX 4090 with its bazillion CUDA cores. If your brain’s spinning trying to grasp this combo’s power, you’re not alone. Seen it in a couple of massive laptops like the MSI Titan 18 HX and Alienware m18 R4, so this one being just 12.5 inches feels… not as crazy? Maybe?

Anyway, Qingchen crammed all this firepower into the handheld and, surprisingly, it doesn’t melt. The GPU hangs out under 72°C while feasting on games like God of War in 4K. That’s cooler than I expected.

Also, it’s got a cool 64GB of RAM and two 2TB SSDs. You wanna upgrade? Go wild. But fair warning, that 50Wh battery? You might wanna keep it close to a power outlet. Sounds like this is just the start, and Nvidia might be cooking up something with the N1 and N1X for 2026. Meanwhile, AMD’s probably plotting their next move.

I stumbled here, but hey, Tom’s Hardware has way more of this bunny-trail tech stuff if you’re into it. Just go click around.
