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

Sure thing. Here’s a reworked version of the article:

So, there’s this person, right? A tech enthusiast in China — calls themselves Qingchen DIY on Bilibili — who’s kind of blown the lid off traditional gaming handhelds. They went all out and slapped a whopping 12.5-inch 4K screen onto this thing. It’s wild. And get this, it’s powered by an Intel Core i9-14900HX CPU. Yeah, the beefy one. But what really seals the deal? An Nvidia GeForce RTX 4090 Laptop GPU. Who does that?!

Okay, so here’s the scoop. Normally, AMD rules the whole handheld gaming scene with those swanky little CPU and GPU combos. Like in the Asus ROG Ally X and Steam Deck OLED — all those pocket-sized wonders. Then there was this fierce game-changer from Intel last year with its Lunar Lake or Lunar Lake-something handheld. Not going to lie, I didn’t catch all the details, but it sounds intense. But Qingchen DIY? They’re dreaming of a world where the Intel and Nvidia duo shines in this handheld circus. Really breaking some boundaries here.

Oh! They molded this whole contraption using a Tongfang chassis. Now, Tongfang might not ring a bell, but you’d be surprised. They’re this Hong Kong entity that whispers in the shadows for big names like PC Specialist or XMG or whatever. Kind of like the wizard behind the curtains sort of deal.

Now, let’s talk guts. Inside this bad boy, it’s like a processing paradise. There’s the i9-14900HX CPU with, oh, something like 8 big-boy cores and 16 littler ones, you know? And it’s paired with that monster-y RTX 4090 GPU, with its 16GB of VRAM and like, a gazillion CUDA cores. The numbers make my head spin.

If you’re trying to wrap your mind around how big a deal this is, let me lay it out: imagine the MSI Titan 18 HX or the Alienware m18 R4. Big as trucks. And they’re driven by the same Intel/Nvidia mashup, making this 12.5-inch gizmo feel like, okay, manageable? Sort of like carrying a brick, but techier.

Oops, sidetracked. Right, anyway, even with its smaller size, the modder swears it doesn’t fry itself. Temperatures stay below 72°C — seriously impressive — even in heavyweight games like God of War. Is it just me or does 175W sound like a lot for something this compact? Oh, and don’t get me started on that screen. A 4K IPS display — crisp city.

Then you’ve got a whopping 64GB of DDR5-5600 RAM and dual 2TB SSDs. That’s, uh, enough space to store a mammoth, I suppose. And pull up a chair for this one: a 50Wh battery. Just, maybe keep a charger handy? Just in case, you know.

While we’re here dreaming about Intel + Nvidia handhelds hitting the mainstream, which we all desperately want, rumor has it Nvidia’s cooking up something special for 2026. The Nvidia N1 or N1X might sneak in with some crazy 20-core, Arm-wielding magic. I don’t really know what that means, but it sounds cool. AMD, you ready?

And hey, make sure to keep tabs on Tom’s Hardware on Google News if you’re into the nitty-gritty of this tech madness. I think there’s a Follow button somewhere there. Maybe.
