Nvidia increased the TDP of the RTX 4080 to 420W

In the past period of time, when it comes to GeForce RTX 40 series graphics cards based on Ada Lovelace architecture GPU, power consumption has always been a topic of concern. Especially for high-end graphics cards such as GeForce RTX 4080/RTX 4090, with the introduction of the 16Pin PCIe 5.0 power supply interface, it seems that manufacturers can be more determined to challenge the performance limit by increasing power consumption.

Recently, Twitter user @kopite7kimi revealed that the graphics card with the PCB design of PG139-SKU360 may have a power consumption of 420W, which corresponds to the AD103 GPU, that is, the GeForce RTX 4080. This means that the TDP is directly increased by 100W compared to the current GeForce RTX 3080.

According to past news, GeForce RTX 4080 and GeForce RTX 4090 share part of the PCB design, AD103 and AD102 may be compatible in terms of pins. At the same time, Nvidia’s partners can use the same thermal design for both graphics cards. It has been previously reported that the TDP of the GeForce RTX 4060 with AD104 will reach 220W, which is higher than the current GeForce RTX 3070.
