This still remains a rumor, but after reports that the RTX 5090 could already have a TDP of 600 watts ex works without OC, a new leak now indicates 575 watts for the new top-of-the-line GeForce RTX model. This would be 125 watts more than the RTX 4090. The RTX 5080 should have 360 watts, which is 40 watts more than the RTX 4080 (Super).
400 watts was last mentioned for the GeForce RTX 5080, which will most likely be the first model of the new series to hit the market on January 21.
575 Watt: The standard TDP of the RTX 5090 Founders Edition?
It remains to be seen whether the 575 watts actually corresponds to the standard TDP of the Founders Edition and therefore the base TDP of the class. It’s possible that the high power figures are still based on the maximum TDP of the card (which can be achieved after increasing the power target) or the TDP of overclocked custom designs.
On the other hand, the enormous increase in execution units without a decisive leap in manufacturing technology and the new GDDR7 memory with a capacity of 32 GB suggest that the TDP of the top model must increase to be able to show a significant jump in performance. compared to the RTX 4090.
