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

So, there’s this tech wizard in China, right? Goes by Qingchen DIY on Bilibili. And they’ve made something… I dunno, kind of wild? Imagine a handheld gaming device that’s practically the size of a small TV. Like, we’re talking 12.5 inches of pure 4K display goodness. And just because they can, they slapped an Intel Core i9-14900HX in there. But wait, there’s more — it’s also got an Nvidia GeForce RTX 4090 Laptop GPU. Madness, right?

AMD’s been on a roll, owning the handheld scene with those tiny yet mighty APUs. You know, like how the Asus ROG Ally X and Steam Deck OLED pop up everywhere. Intel tried getting in the mix too, remember MSI’s Lunar Lake handheld? If not, no biggie. But the real shocker here is seeing Intel and Nvidia dance together in the handheld space. I guess Qingchen DIY just wanted to see if it could work. Spoiler: it totally does.

Now here’s where it gets craftier: Qingchen took a Tongfang chassis. What’s Tongfang? Honestly, until I dug into this, I had no idea either. It’s some company over in Hong Kong crafting stuff for PC brands you’ve probably heard of, like XMG and Maingear. Anyway, the chassis got cut down into a handheld. The skills involved? Next level.

Inside this contraption, it’s packed with the i9-14900HX — all those cores and such — and then there’s the RTX 4090 doing its thing with 16GB of VRAM. Picturing that much power in something this “small” blows my mind. Think about those monster laptops like the MSI Titan 18 HX. Yeah, those. This handheld’s not nearly as beastly in size, but performance-wise? Competitive.

Now, temperatures. You’d think cramming that much power into a handheld would make it melt, but nah, it stays cool enough. The words “God of War” and “Horizon Forbidden West” even get thrown around. Those are some heavy hitters. Yet, the GPU keeps it chill under 72°C. Somehow. I mean, playing at native resolution on that sweet 4K display takes some serious juice.

Quick detour into specs: this bad boy’s got 64GB of RAM (DDR5-5600, if you’re keeping notes) and a couple of 2TB SSDs — all nice and upgradable, they say. And the battery? 50Wh. Don’t expect it to last ages away from a socket.

Wrapping it up, a commercial Intel + Nvidia handheld isn’t around the corner. But who knows? Nvidia might just break out on their own soon. Maybe by 2026 with that cool-sounding Nvidia N1 chip, featuring a zillion cores or something. Well, okay, like 20 Arm cores and a Blackwell GPU. It’s all specs this and specs that. But hey, AMD’s got time to respond.
