Why do laptops use dual 1080s instead of single 1080ti?

Hello, host.

Theoretically speaking, the power consumption of GTX1080 is about 190W, and the power consumption of GTX1080TI is about 250W. The power consumption of two GTX1080s is higher than that of one GTX1080TI anyway. Why is there no notebook with a single GTX1080TI? Woolen cloth?

The most important factor restricting notebook performance is heat, and performance and power consumption are positively correlated. Once you understand this, you can easily understand why there is no single GTX1080TI in the notebook.

For example:

The above picture is the disassembly diagram of the Shenzhou Ares GX10. It uses the Blue Sky P870DM mold. The heat dissipation specifications of this mold are very luxurious, and the heat distribution is super large. The board plus three fans and eight heat pipes can be equipped with up to two GXT1080 graphics cards.

This type of heat dissipation mold can be said to be top-notch in notebooks, but it is still not enough to support the heating of a single GTX1080TI. The reason is very simple. The core area of ??a single GTX1080TI is small and the unit heat is too high. On the other hand, GTX1080sli has two cores separated for heat dissipation, so the core area is much larger. If this mold can suppress the maximum power consumption of a single core of 200W, then the 190W of the GTX1080 is just enough, while the 250W of the GTX1080TI is enough.

Since the development of gaming laptops, power consumption and performance have always been unavoidable topics. Under the same power consumption, achieving greater performance through advancements in architecture and technology is a worldwide problem. . Previously, Nvidia released a special MAX-Q graphics card for mobile devices to improve this problem, claiming that it can make gaming laptops the same as thin and light laptops. Facts have proved that ordinary consumers have not enjoyed the experience brought by high technology. The reason is simply that it is too expensive. I can’t help but lament that poverty limits my imagination.

In order to solve the problem of heat generation and bring a better gaming experience, top gaming laptops even use water cooling. As shown in the picture, the ASUS ROGGX800 uses both water cooling and air cooling, which is really cruel.
