Undoubtedly, the development of GPU has been driving the "progression" of heat dissipation technology. It seems that each generation of high-end products will change new tricks. According to recent demonstrations, AMD's next-generation high-end version of the Radeon HD 7900 series based on the new architecture will use the so-called "Liquid Chamber Cooling Technology."
AMD and NVIDIA have already introduced vacuum chamber heatsink technology on high-end graphics cards, but this is obviously not enough to meet the new high-end core, so the new liquid cavity cooling debut.
According to the introduction, the vacuum chamber is a two-phase design based on evaporation. The heat dissipation in the liquid chamber is changed to a two-phase design based on pool boiling, and the capillary structure is eliminated, making the whole simpler and easier to manufacture.
The closest to the GPU in the bottom of the liquid chamber is a layer of microporous paint that is immersed in a large pool of liquid (unique materials are unknown). Heat is transmitted from the GPU through the microporous paint, which heats the liquid to boil off and then condenses on both sides into drops of water that circulate back and forth.
AMD claims that the reliability of heat dissipation in the liquid chamber is higher than that of the vacuum chamber and there is no problem of freezing failure.
According to Matt Skynner, AMD's senior vice president and general manager of the graphics division, the mobile version of the Radeon HD 7000 series has already begun shipping and will be launched simultaneously on both the notebook and desktop platforms.
