Leaked power specifications of Nvidia's RTX 5090 and RTX 5080 GPUs allege up to 27% increase in power compared to the last generation, though still less than initially expected, courtesy of KopiteKimi and hongxing2020 at X. We aren't sure if these numbers correspond to the TGP or TDP. However the numbers still offer a glimpse of what to expect from Nvidia's next-gen Blackwell GPUs; which are alleged to be announced by Nvidia Founder and CEO Jensen Huang during his January 6 keynote.
A few months ago, preliminary details suggested that the RTX 5090 and RTX 5080 would consume upwards of 400W and 600W of power, respectively. It seems the power rating has been toned down, to some extent at least. Still, these numbers show a notable increase over the last generation (Ada) and the previous generation (Ampere).
