NVIDIA GeForce RTX 4090 GPU Estimated Power Consumption Is 450 Watts Alone

NVIDIA GeForce RTX 4090 GPU is a gaming graphics card released in September 2018. It uses GDDR6 memory and has 8GB of video RAM, so it should be able to run games at 4K resolution with high textures.

The “NVIDIA GeForce RTX 4090 power consumption” is the estimated power consumption of a single NVIDIA GeForce RTX 4090 GPU. The card alone draws 450 watts.

Those of us who believe we can power the next generation of flagship graphics cards using passive PSUs look to be in for a rough time. Igor Wallosek has released his predictions for the GeForce RTX 4090’s power consumption, which suggest that the GPU’s Lovelace-based GPU alone might require 450 watts. This is the same graphics card power as NVIDIA’s newly released GeForce RTX 3090 Ti, which is already 100 watts more powerful than its ordinary version. Wallosek’s calculations also reveal that the GeForce RTX 40 Series will feature variants with TGPs of up to 600 watts, as rumors have predicted.

Where the NVIDIA GeForce “RTX 4090” gets its 600 watts from – a GPU and component calculation | EXCLUSIVE (Igor’s Lab)

The board power TGB of the huge Ada card (whether it will be dubbed RTX 4090 or not) is 600 watts this time, which should be deemed set. This time, we want to figure out how much money is still left over for the chip. And here is where it becomes fascinating, because based on previous generations, you can predict voltage transformer losses, extra-low voltages, and other losses very effectively. Because I’m not a psychic, I specifically inquired about the memory. Micron is within the ranges of what should be predicted owing to the higher clock with 3.4 watts per module (according to my research). The storage increase is really an afterthought. Instead of the GeForce RTX 3090’s 60 watts, the overall power consumption for 24 GB (12 modules) is about 40 to 41 watts.

In this basic design, the four memory voltage converters should have an efficiency of roughly 60 to 70%. I plan about 15 watts of losses for the whole circuit, including the MOSFETs, coils, and caps, with the components involved. This isn’t insignificant, but it’s also not exceptional. I set roughly 10 watts for the low voltages with the standard 1.2 volts, 1.8 volts, 5 volts and other things like the MCU, the shunts, the rail filtering, etc., and an average of 5 watts for the fans, despite rumors that they would not be directly included in the limit.

If you extrapolate the power consumption and look at the traces, you may practically double the board losses since more phases equals more conductor traces. If the GPU voltage converters (NVVDD) are identical to those found in the 3090 Ti, they should have an efficiency of about 90%, resulting in a power consumption of around 50 watts. This is also around twice the amount of heat generated by the RTX 3090, leaving approximately 450 watts for the GPU. In comparison, the AD102 would only use slightly less than twice as much electricity.
