A China-based computing enthusiast and modder has created a gaming handheld modder known as Qingchen DIY. This custom-built device, showcased on Bilibili, crams high-end laptop components into a handheld form factor, delivering desktop-level power with a 12.5-inch 4K touchscreen display. Powered by an NVIDIA GeForce RTX 4090 Laptop GPU and an Intel Core i9-14900HX processor, this beastly handheld runs demanding AAA titles like Cyberpunk 2077 and God of War at 4K resolution with impressive frame rates. Here’s a closer look at this groundbreaking creation that’s making waves in the tech and gaming communities.

This DIY handheld lies the NVIDIA GeForce RTX 4090 Laptop GPU, boasting 9,728 CUDA cores and 16GB of GDDR6 VRAM. Paired with an Intel Core i9-14900HX processor, featuring 24 cores (8 performance and 16 efficiency), this console is essentially a high-end gaming laptop reimagined as a portable device. The system is further equipped with 64GB of DDR5-5600 RAM and a 2TB PCIe 4.0 NVMe SSD, ensuring lightning-fast load times and ample storage for modern AAA titles.
The display is equally impressive: a 12.5-inch IPS touchscreen sourced from a Dell laptop, offering a crisp 4K resolution (3,840 x 2,160 pixels). This high-resolution panel ensures that games like Cyberpunk 2077 and God of War look stunning, with the hardware capable of pushing frame rates that rival traditional gaming rigs. The modder retained the laptop’s original mainboard and cooling system, a clever design choice that keeps the GPU below 72°C and the CPU around 65°C under load, even when running demanding titles at 4K.

Qingchen DIY’s creation is a performance juggernaut. In demonstrations, the handheld ran Cyberpunk 2077 at 4K with over 60 FPS and God of War (2018) at an astonishing 100–120 FPS, all while maintaining stable thermals. Horizon Forbidden West also performed flawlessly, showcasing the console’s ability to handle graphically intensive games with ease. While it’s unclear whether technologies like DLSS were used, the raw power of the RTX 4090 ensures smooth gameplay even at maxed-out settings.

The console’s design, built on a Tongfang chassis, incorporates familiar gaming controls, including dual analog sticks, a D-pad, action buttons, and additional function keys. It also retains the laptop’s ports HDMI, Ethernet, USB Type-C, Type-A, and an SD card reader making it versatile for external displays or peripherals. However, the device’s 50Wh battery is a limiting factor, with its 174W power draw suggesting short playtimes without an external power source. For extended sessions, users will likely need to keep it plugged in, somewhat undermining the “portable” aspect but not its performance.
