AMD Radeon RX 7000 GPU will not use 12VHPWR interface

As AMD finalizes the release time of the RDNA 3 architecture GPU, recent related news has gradually increased. Recently, Scott Herkelman, senior vice president and general manager of AMD’s Radeon Graphics Group, said on his Twitter account that the graphics card equipped with the RDNA 3 architecture GPU would not use the new 16Pin PCIe 5.0 external power supply interface, which is the 12VHPWR interface.

It has been reported before that AMD’s public graphics cards equipped with Navi 31 will not use the 12VHPWR interface, and until now, its partners’ non-public products have not confirmed this new interface. Although there were early rumors that AMD would be equipped with two 8Pin power supply ports for graphics cards equipped with Navi 3x, the flagship model seems to be equipped with three 8Pin power supply ports to meet the power supply requirements.
Nvidia has equipped its GeForce RTX 40 series graphics cards based on the Ada Lovelace architecture with a 12VHPWR interface. However, recently there have been reports about the overheating and melting of the 12VHPWR interface on the GeForce RTX 4090 graphics card used by users. Some users are concerned about this interface that supports up to 600W power supply. Since Intel does not currently use the 12VHPWR interface, it is likely that Nvidia will still be the only manufacturer to use the 12VHPWR interface on graphics cards for some time.

AMD will host a special live event called “together we advance_gaming” on November 3, 2022, to introduce the next generation of Radeon graphics cards. AMD executives will then detail the high-performance, high-efficiency RDNA 3 architecture that provides gamers and content creators with new levels of performance, power efficiency, and functionality.
