Total Power Consumption Can Reach 600W with RTX 4090

NVIDIA’s next-generation flagship graphics card is expected to consume 450W of power for the GPU alone, and the card as a whole (TGP) is expected to reach as high as 600W. These estimates are based on a reliable source of information from within the industry in general. Igor WallossekIt came from

Wallossek says that NVIDIA is preparing for the RTX 4090, which is expected this year, with the GeForce RTX 3090 Ti, which it has recently launched. According to the source, the PCBs used in the GeForce RTX 3090 Tis are similar to the PCBs that will be used in the next-gen RTX 40 series, and even the manufacturing partners are said to have confirmed this. The board design may not be exactly the same, but overall the design will be similar when it comes to power dissipation/consumption.

Igor’s Lab editor points out a 600W TGP, with contacts in industry sources and hints observed with the RTX 40090 Ti. As we mentioned earlier, the upcoming RTX 40 series NVIDIA graphics cards will be built on the Ada Lovelace architecture. In fact, high figures such as 600W were mentioned in the past.

With Ada Lovelace GPUs like the RTX 4090, Micron’s newer GDDR6X memory is expected to consume ~20W less power than previous versions. With VRAMs the speed will increase, but due to the increased density the amount of memory chips used can be halved. For 450W maximum GPU consumption, factors such as MOSFETs, fans, PCB losses and a large amount of wasted energy to be converted into heat are mentioned.

Previous leaks suggest that the GPU used in the GTX 4090 (possibly AD102) will offer 18,432 CUDA cores (75% more than the RTX 3090). We don’t expect these cards to be on the market until at least September. As the time approaches, leaks about the new architecture and RTX 40 series cards will intensify. There may also be some official promotions from NVIDIA along with Computex. Finally, to reiterate, these power calculations are based on industry sources and component assumptions.
