It’s no secret that mobile and desktop video cards differ significantly. For example, the same mobile GeForce RTX 4090 is based on a different graphics processor (AD103 instead of AD102), which has 41% fewer graphics cores compared to the desktop chip. In addition, the mobile card has 8 GB less memory and operates at a significantly lower TDP (typically 175 W), while the stated TDP of the desktop version can reach 600 W.
However, a Chinese modder and enthusiast with a pseudonym that translates from Chinese as “Beginner who loves overclocking” decided to build a laptop equipped with the desktop flagship card of the Ada Lovelace generation. The resulting result can hardly be called a laptop in the full sense of the word, since desktop PC components were used to create it. The system is based on a barebone platform based on the ROG STRIX B650I Mini-ITX motherboard and the Ryzen 9 7950X3D desktop gaming processor, which is cooled by a low-profile cooler. The machine also received 32 GB of DDR5-6800 RAM and an Intel Optane P5800 SSD.
The key component of the system is the video card. A desktop GeForce RTX 4090 is installed here, equipped with a cooling system with a tangential fan and having a declared TDP of 450 W. The enthusiast also added a custom sound system to the laptop, which uses two speakers with a power of 20 W each.
According to a short review of the assembled system, the computer is very stable, and the video card with a TDP of 450 W easily realizes its performance potential. The enthusiast notes that in games the temperature of the video card reaches 70 degrees Celsius. There are no crashes, which is confirmed by a multi-hour gaming session in Naraka Bladepoint.
The enthusiast admitted that he assembled the laptop to order. According to him, it is possible to create the same system, but based on a Core i9-14900K processor (with a TDP of up to 200 W). The laptop does not have its own battery. It requires constant connection to an external power source. At peak load, such a system could easily consume 600 watts, so equipping a laptop with a battery would simply not be practical.
The good news is that this laptop fits in a backpack. The bad news is that the system weighs almost 7 kg, and with an external power supply it weighs only 8 kg. Unfortunately, the enthusiast did not record a video of the laptop working. But something tells me that this system cannot be called quiet.
