No fewer than two reliable insiders have spoken out about the power requirements of the next generation of Nvidia GPUs. The new RTX 40 Series could take “450 to 850 watts” TGPs.
Greymon55 claims that Lovelace should be officially released next September. It is expected that the AD102 GPU, probably the heaviest chipset from the Lovelace generation, will come with three different ‘total graphics power’ (TGP) regulations. The wattages would be:
- 450 watts
- 650 watts
- 850 watts
Although this would not necessarily concern the “final specifications”.
kopite7kimi responded with somewhat different information, with the emphasis that these are rumors. According to the second nice on duty, the power requirements would be 450, 600, and 800 watts, for the RTX 4080, RTX 4080 Ti, and RTX 4090 respectively.
The expected wattages (just like the precise names of the GPUs) are still far from definitive, let alone confirmed by official sources. Nevertheless, the two goodies are currently known as voices of integrity in the hardware leak circuit. Kopite7kimi later estimated the reliability of its sources at ” 50/50 “.
The expectation that some GPUs may require (well) above 600 watts of power is certainly remarkable. After all, the new generation of cards will most likely switch to the new PCIe 5.0 power cables, which are being labeled the new standard for heavy, next-gen video cards. However, the new power cable draws a maximum of 600 watts from a power supply, which still would not be sufficient for some of the TGPs mentioned.
Nvidia itself has not yet made an official word about specifications surrounding the new Lovelace GPUs. In any case, the RTX 3090 Ti must still be launched in the current Ampere generation, which seems to have been quietly postponed since January.
