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

Hey, so there’s this wild story I stumbled across about this gaming handheld. Imagine a 12.5-inch monster of a machine with a 4K screen. Crazy, right? Guy named Qingchen DIY—I think he’s kinda famous on Bilibili for this stuff—decided to experiment beyond belief. Picture this: he slapped in an Intel Core i9-14900HX. Like, who does that? Oh, and it’s paired with an Nvidia GeForce RTX 4090 Laptop GPU. Talk about over the top!

Now, usually AMD is running the show when it comes to these handheld gaming gadgets. I mean, the Asus ROG Ally X and the Steam Deck OLED are killer with their fancy APUs. Intel took a swing with something with MSI too, but usually you don’t see Intel and Nvidia cozied up like this in a handheld. Guess this dude, Qingchen, was just curious—what if the two powerhouses, Intel and Nvidia, joined forces?

In this Bilibili vid he posted, Qingchen shows off this handheld he made by tweaking a Tongfang chassis. Funny thing, you probably don’t even know it, but Tongfang’s kinda behind a lot of brands you’ve heard of like PC Specialist, XMG, and others.

Dude didn’t hold back—packed in the i9-14900HX with its 8 P-cores and 16 E-cores. And yeah, the RTX 4090 GPU is there, rocking 9,728 CUDA cores. Mind-blowing, really. Might seem like science fiction, but if you’ve seen laptops like the MSI Titan 18 HX or the Alienware m18 R4—it’s basically that kind of power squished into something way smaller.

You might think it’d overheat like mad, but nope. Qingchen says the GPU keeps cool even when playing intense games like God of War. We’re talking under 72°C and munching through 175W. Let me tell ya, that’s no small feat on a 4K display.

Some more specs for ya nerds: 64GB of DDR5-5600 RAM, dual 2TB SSDs. Swappable, if you’re feeling adventurous. It’s got a wee 50Wh battery that might not have endurance for marathon sessions, though. So, you might want to hover near a power plug.

Anyway, we’re not seeing a real Intel + Nvidia handheld hitting stores tomorrow. Maybe Nvidia’s cooking something alone—think N1 and N1X for 2026. AMD better watch out!

Anyway, just had to share this tech insanity. Catch ya on the flip side!
