Modder Creates 15-Pound Laptop with Desktop RTX 4090 and Ryzen 9 7950X3D

A Chinese modder has built a custom laptop featuring a full desktop RTX 4090 GPU and Ryzen 9 7950X3D CPU, weighing nearly 7kg.

Using a barebones OEM laptop chassis, the modder installed a desktop RTX 4090 GPU and AMD Ryzen 9 7950X3D CPU.
The laptop includes 32GB of DDR5-6800 RAM and an Intel Optane P5800 SSD, enhancing its high-end performance.
The RTX 4090 maintains its full 450W TDP, achieving a 3DMark Time Spy score of 28,490 and stable temperatures in the 70s Celsius.
The device, which weighs around 15 pounds (7kg), fits in a backpack but lacks a battery, requiring a constant power outlet.
The project highlights the significant performance gap between Nvidia's desktop and mobile RTX 4090 GPUs.
