Power consumption rumors surrounding Nvidia's next-gen Ada Lovelace GPU architecture - the one that's going to succeed the current Ampere-based RTX 3000 series - have struck, and the purported figures are quite insane. The stories suggest Nvidia may be going all out in terms of power draw as the RTX 4090 is allegedly going to feature 600W Total Graphics Power (TGP) according to renowned leakster and Twitter user kopite7kimi.

I think it's too early to talk about it.
For some comparison, the current-gen RTX 3090 features a TGP of 350W, and the upcoming RTX 3090 Ti that's launching soon, is going to pack a 450W TGP. Hence, the next-gen RTX 4090 is allegedly going to consume nearly double (+71%) the power of its direct predecessor and a third more than the Ti variant.
The rumor is not entirely new either as reputed leaker and YouTuber Moore's Law Is Dead (MLID) also says that sources close to it are giving similar figures, and the TGP numbers are hovering around 450W to 600W.
MILD claims that Nvidia is pushing Ada Lovelace very hard as the rumored AMD RDNA 3 performance is really good and Nvidia doesn't want to lose its performance crown.
To be fair to AMD, RDNA 2 is also quite potent in terms of raw rasterization and power efficiency however the ray-tracing performance does leave much to be desired.
