Modder Crafts Gaming Handheld Featuring RTX 4090 Laptop GPU and Intel i9-14900HX — Features 12.5-inch 4K Display and 175W Mobile GPU

Sure thing, let’s dive into this tech tale:

—

Okay, so there’s this person in China, some modder dude, or maybe dudette, who just went nuts and built this colossal handheld gaming thing. Over on Bilibili, they’re called Qingchen DIY. Picture this: a 12.5-inch thing with a crazy 4K display. I mean, why not, right? Under the hood, it’s powered by an Intel Core i9-14900HX CPU, which, let’s face it, is like bringing a bazooka to a knife fight. And speaking of overkill, they slapped an Nvidia GeForce RTX 4090 Laptop GPU in there, too. I’m not joking.

AMD’s been owning the whole PC gaming handheld scene with their compact tech wonders like the Asus ROG Ally X and Steam Deck OLED. Intel threw their hat in the ring last year with MSI’s Lunar Lake. But the classic Intel CPU and Nvidia GPU combo—yeah, it hadn’t made the jump to these mini gaming rigs yet. Maybe this Qingchen DIY person was curious. Like, what if Intel and Nvidia decided to cozy up in this field, right?

Anyway, so the modder—you know, the one with apparently too much time on their hands—grabbed a Tongfang chassis. Tongfang, in case you’re wondering, is this Hong Kong-based company that many famous PC brands have under their hood. Bet you didn’t know that. Anyway, they Frankenstein-ed this thing into what it is now.

Inside this beast? Two of the most potent processors available. The i9-14900HX is like 8 big cores chilling with 16 smaller ones, and the RTX 4090 Laptop GPU has like, what, 9,728 CUDA cores and 16GB VRAM? Try wrapping your head around that in something hand-held. I mean, we thought the beefy MSI Titan 18 HX and Alienware m18 R4 were intense. But this smaller setup might just be packing more punch per inch.

Now, I know what you’re thinking—doesn’t this handheld explode or catch fire under pressure? Surprisingly, not. Qingchen kept the GPU temps under 72°C during heavy gaming sessions like God of War and Horizon Forbidden West. Somehow, this tiny monster sips just 175W even at 4K. Voodoo magic? Maybe.

Oh, and in case you’re keeping score—it comes with 64GB of DDR5-5600 RAM and two 2TB SSDs. And you can upgrade them. But hey, don’t expect it to last long between charges. That 50Wh battery probably only holds out for quick gaming bursts before you’re desperately hunting for an outlet.

Commercial versions? That world’s still a dreamland. I mean, maybe Nvidia will go rogue, who knows? They’re cooking up the Nvidia N1 and N1X for 2026 or something, sporting up to 20 Arm cores. Talk about future-proofing, eh? In the meantime, AMD’s got their own tricks up their sleeve for the portable gaming world.

So, yeah. That’s the wild world of tech for you. Expect the unexpected, as they say.
