NVIDIA GeForce RTX 5090 Features 575 W TDP, RTX 5080 Carries 360 W TDP
According to two of the most accurate leakers, kopite7kimi and hongxing2020, NVIDIA's GeForce RTX 5090 and RTX 5080 will feature 575 W and 360 W TDP, respectively. Previously, rumors have pointed out that these GPU SKUs carry 600 W and 400 W TGPs, which translates into total graphics power, meaning that an entire GPU with its RAM and everything else draws a certain amount of power. However, TDP (thermal design power) is a more specific value attributed to the GPU die or the specific SKU in question. According to the latest leaks, 575 Watts are dedicated to the GB202-300-A1 GPU die in the GeForce RTX 5090, while 25 Watts are for GDDR7 memory and other components on the PCB.
For the RTX 5080, the GB203-400-A1 chip is supposedly drawing 360 Watts of power alone, while 40 Watts are set aside for GDDR7 memory and other components in the PC. The lower-end RTX 5080 uses more power than the RTX 5090 because its GDDR7 memory modules reportedly run at 30 Gbps, while the RTX 5090 uses GDDR7 memory modules with 28 Gbps speeds. Indeed, the RTX 5090 uses more modules or higher capacity modules, but the first-generation GDDR7 memory could require more power to reach the 30 Gbps threshold. Hence, more power is set aside for that. In future GDDR7 iterations, more speed could be easily achieved without much more power.

On a lower class card, the differences are even smaller.
IMO, XX90 is meant for gaming but buying this card aimed at gaming is beyond clueless.
Good system, in winter or summer
Winter times cost lot more than summer times, but i realy dont care anymore bc i sold lot of those Xlm/Xrp +500% profit.
So i can buy 100x 5090 atm if price is 2490e/eachif u know anything about OC
its 120% powerlimit slider.
it gives more room for OC
Also if the 5090 really has a 575W TDP then you can be sure that AIB OC models will get 2x 12V-2x6 connectors with a ~700W BIOS (or more for Overclocking).
Stock BIOS my TUF 4090 goes up to 600W already.
1200W for a GPU would be nonsense though. I hope we never get there! It's going to create so much heat...
there is basically no vram usage limit when using big models, ai image & video generation and those dudes run a lot of gpus in same rig
Nvidia makes 1,000w GPUs

But yeah, running 2 of those with PCIe 5.0 is gonna be really nice and still really useful for the cases you mentioned.
