The little sister GeForce RTX 5080 is said to be "only" 360 watts.
With just a few days to go before the official presentation of NVIDIA's new GeForce RTX 50 series "Blackwell" graphics cards, information is becoming more and more precise, even if it should be borne in mind that these are still only rumours. The informants are respected, their sources seem reliable, but NVIDIA is still making no comment whatsoever: we'll have to wait for the keynote by Jensen Huang, the company's co-founder and CEO, on the night of January 6 to 7 to find out for sure.
However, the latest rumours focus on a particularly important and much-discussed point: the future power consumption of these graphics cards, which already promise to be insanely powerful. This is especially true of the GeForce RTX 5090 - the most powerful model yet to be announced - which is expected to feature a total of 2,760 CUDA cores, for computing power never before seen on a "mainstream" graphics card. Just think: the GeForce RTX 4090 had "only" 16384 CUDA cores.

Inevitably, such power implies higher power consumption. However, the latest rumors are almost positive in that they point to a drop in power consumption compared to what was previously expected. There was talk of a TDP of 600 watts, but on X.com, hongxing2020 and kopite7kimi have both mentioned a TDP of 575 watts. These 25 watts less are therefore a pleasant surprise, but still confirm a clear increase on the 450 watts of the GeForce RTX 4090.
The same applies, more or less, to the GeForce RTX 5080. Previous rumors claimed a TDP of 400 watts, but our two informants now temper this information: this model is said to be "only" 360 watts. The 40-watt benefit is interesting, but once again, it confirms a clear inflation compared to the 4000 generation: we're effectively 40 watts above the TDP of the GeForce RTX 4080. The GeForce RTX 50 series will undoubtedly be powerful, but energy savings are out of the question with these monsters.
